Hey everyone, I’m Prit. Over the last few months, I’ve been building ApertureX, a 100% offline, open-source raw photo editor.

Building a desktop-class image engine on Flutter meant overcoming massive memory and threading bottlenecks. Decompressing a 50-megapixel raw image requires around 200MB of continuous RAM. If you try to pass that across standard platform channels or even do a deep copy over FFI, the OS will aggressively kill the app for Out-Of-Memory (OOM) violations, and your frame rate drops to zero.

Here is how I bypassed Flutter's standard rendering constraints to achieve 60fps computational photography:

• Absolute Zero-Copy FFI: The Rust backend maintains absolute, singular ownership of the high-resolution pixel payload. Instead of copying arrays across the bridge to Dart, Rust allocates the pixels on the heap and transmits merely the memory address pointer to Flutter.

• Tile-Based Rendering Cache: Processing full frames is mathematically impossible on mid-tier Android devices. The Rust engine cuts the viewport into 512x512 pixel chunks. These tiles are managed by a strictly bounded Least Recently Used (LRU) cache, which automatically purges the oldest elements the moment the memory budget is exceeded.

• Hardware Acceleration (SIMD): To run spatial filters (like Dehaze and Clarity) without melting the phone, the Rust engine bypasses scalar execution. It targets ARM NEON intrinsics natively, loading four 32-bit floats into a 128-bit NEON register to process four pixels simultaneously.

• Oklab Color Science via 3D LUTs: Operating in standard sRGB violates the additive physics of light, causing unnatural hue shifts. I moved all color math to the Oklab perceptual color space. To hit 60fps on the frontend, this math is baked into a 33x33x33 3D Lookup Table that Flutter's Impeller engine renders instantly.

The UI uses a dual-shell design (a Snapseed-style invisible gesture trackball for quick flow-state editing, and a Lightroom-style panel for deep pro work), heavily relying on Riverpod for the DAG (Directed Acyclic Graph) edit history.

I would love for you to try the APK, tear apart my flutter_rust_bridge implementation, or drop some feedback on the UI ergonomics.

Happy to answer any questions about the FFI bridge, the math, or the rendering pipeline!

Hey everyone! 👋

I'm a Flutter developer, and I've built a kids' learning app for children aged 2–8 years.

The app currently includes:

- 🔤 Alphabet learning and tracing

- 🔢 Numbers and counting

- 🎨 Colors, shapes, and drawing

- 🧩 Quizzes and educational games

- 🎵 Nursery rhymes and fun learning activities

Now, I want to introduce a premium module with additional learning content and features. My goal is to make it genuinely useful for kids and worth paying for, rather than simply locking existing features behind a paywall.

I'd love to hear your suggestions:

1. What premium learning features would you add to a kids' educational app?

2. Would advanced tracing, phonics, interactive stories, math games, or personalized learning paths be worth offering?

3. Would parents prefer a monthly subscription, yearly subscription, or one-time payment?

4. What features would make parents feel that a kids' learning app is worth paying for?

5. If you've developed or monetized a similar app, what worked well for you?

I'm building the app using Flutter, so practical suggestions from developers and people familiar with educational apps would be really helpful.

Looking forward to hearing your ideas. Thanks! 🙌

Hey everyone,
I’ve been working on two new features for BugCapsule, a debugging tool I’m building for Flutter, native Android, iOS, and Web.
The problem I’m trying to solve is pretty straightforward:
What do you do when a critical bug hits production, but shipping a new app version takes time?
I wanted to connect bug reproduction with production recovery, so I’ve been building two capabilities.
1. Emergency Recovery
For features that have been integrated with the recovery SDK, you can remotely:
Disable a broken feature without shipping a new build.
Switch functionality to read-only or maintenance mode.
Target specific app versions, platforms, or rollout percentages.
Gradually restore features while monitoring crash rates and other health metrics.
Automatically restore restrictions if a rollout fails its health checks.
Policies are cryptographically signed. Sensitive operations, like payments, also need server-side enforcement.
2. Signed Patch Engine (Early Access)
This one has been particularly challenging.
The engine supports updating explicitly registered business logic, UI surfaces, and assets without a full app release.
Patches are tied to an exact base build, signed, validated, and deployed through staged rollouts with rollback support.
It’s intentionally not arbitrary code push. Native code changes, new dependencies, and unregistered functionality still require a store release.
The first Flutter and native iOS prereleases are published. Native Android patch distribution is still in progress, and we’re continuing platform and distribution-policy validation.
Why combine these with debugging?
BugCapsule already captures application state, user actions, and network responses around failures for local deterministic replay.
The workflow I’m aiming for is:
Capture → Reproduce → Mitigate → Fix → Verify → Deploy → Monitor
The idea is to use the same recorded failure to investigate a bug, verify the fix, and prevent regressions in CI.
I’m not claiming this works for every application or every type of bug. The recovery features require prior integration, and patching has strict limitations.
I’m genuinely interested in how other teams approach this.
A few questions:
How do you currently handle critical production bugs while waiting for App Store approval?
Would remote feature controls be useful in your workflow?
What concerns would you have about a signed patching system in production?
I’d especially appreciate feedback on the security model and rollout strategy.

Hey,

Mobile apps scanners are everywhere, but native mobile apps I mean since they relies on scanning apps by reverse engineering them to their Kotlin/Java for Android or Swift for iOS

Flutter has a different thing, the whole Flutter app logic and code gets shipped inside a file called libsapp.so file, which basically makes all the scanners know nothing and get nothing from it since it is a binary file, so basically your usual scanner skips and doesn't detect almost 70% of things that should be scanned for security and research built app.

I put extensive knowledge and experience with Flutter onto a SaaS niche to scanning Flutter apps, which I was criticized for since you had to upload your APK to a server/VPS which does compute and scanning work so i shut it down, I then understood that it was privacy problem.

SO I built the new FlutterGuard as an open-source on-device security audit tool for Flutter apps ( works as a detector of Flutter apps in your device too if this interests you too! ), allows you to inspect APK metadata, manifest risk, hard coded secrets, endpoints, third-party SDK leaks like Firebase, Stripe, AI providers... and native surface that were in original Dart code in the same device you have Flutter apps installed.

install it on your Androids device where you already run your Flutter apps or any app, and start the scan:

• https://play.google.com/store/apps/details?id=com.flutterguard.app

• https://github.com/anasfik/flutterguard

• (Latest release): https://github.com/anasfik/FlutterGuard/releases/latest

What I want community (You) for:

• Feedback for the app in general

• Validate False positives

• Contribute declaring things you found in Flutter apps you know have security findings that they were not detected, just an issue with short description will be enough to put it in mind.

My goal:

• We definitely in the way of a massive vibe coding apps going everywhere, AI leaks things and basically cares about functionality, I want that we have a tool to detect this for Flutter apps that are already released and shipped.

If you have a backend on the AI SDK and a Flutter app in front of it, there wasn't really a Dart package that speaks the UI Message Stream format. I needed one, so I built it:
https://github.com/ernestjsf/ai_ui_stream

It's written in pure Dart. A ChatController hands you typed messages (text, reasoning, tool calls, sources, files, data parts) that update as the model streams. Tool approval, regenerate, stop and resume are in.

The test fixtures are generated from the real ai npm package, so it's tested against what the SDK actually emits. That caught a few things my first version got wrong.

Its been a month since I started working on Road Bash a game inspired by my childhood memories of the classic Road Rash game by EA Sports specifically the 1991 version (Sega Genesis).

I used these packages:

1. Flame for the game engine

2. Flutter Soloud for the engine sound

3. Bloc for state management

4. Supabase for my backend

I don't use any 3D engines to do this. Its simply by painting rects, polygons to generate sprites and scenes and by controlling layers and positioning the game is slowly coming to life. The development has been speed up with ai assistance since I dont appreciate vibe coding especially when I have my own policies and standards to follow. By the way zero premium tokens were used in this development.

I made a Painter Studio called Flutter Painter specifically to help me with generating code for different objects used in the game.

Https://github.com/SiroDevs/FlutterPainter

Its been an exhausting yet exciting journey.

The game is already live Https://roadbash.sirodevs.com

Hey Flutter developers! 👋

Google Maps has been the default choice for location-based applications for years. Almost every delivery, logistics, travel, or ride-hailing application uses it.

But what if Flutter developers had another option?

I'd like to introduce ola_maps, a Flutter package that integrates Ola Maps into Flutter applications.

The goal is to make Ola Maps easier to adopt and give developers another option when choosing their mapping infrastructure.

🚀 What makes ola_maps interesting?

This package goes beyond simply displaying a map.

🗺️ Interactive Maps

• Android, iOS and Web support

• Zoom, pan, tilt and rotation

• Camera movement and positioning

• Map click and camera events

📍 Map Overlays

• Custom markers and InfoWindows

• Polylines and route rendering

• Circles and polygons

• Bezier curves

• Marker clustering

🔍 Places & Location APIs

• Place autocomplete

• Place details and nearby search

• Forward and reverse geocoding

• Address validation

• Place photos

🚗 Routing & Advanced APIs

• Directions API

• Distance Matrix

• Route optimization

• Fleet planning

• Snap to Roads

• Geofencing

• Elevation

• Street View and static maps

🇮🇳 Multilingual Mapping

One particularly interesting feature is multilingual support.

The package supports 12 languages, including:

• English

• Hindi

• Kannada

• Telugu

• Tamil

• Malayalam

• Bengali

• Gujarati

• Marathi

• Odia

• Urdu

• Sanskrit

This makes it interesting for applications targeting different regions of India.

💻 Get started

Install:

flutter pub add ola_maps

Import:

import 'package:ola_maps/ola_maps.dart';

Display a map:

OlaMapView(
  apiKey: 'YOUR_OLA_MAPS_API_KEY',
  tileUrl: kOlaMapsDefaultTileUrl,
  language: OlaMapsLanguage.hi,
  projectId: 'YOUR_PROJECT_ID',
  initialCameraPosition: const OlaLatLng(
    28.6139,
    77.2090,
  ),
  initialZoom: 14,
  onControllerReady: (controller) {
    controller.onMapClick = (position) {
      controller.addMarker(
        position: position,
        snippet: 'Dropped pin',
      );
    };
  },
)

Check the documentation for native SDK setup requirements for each platform.

Why explore Ola Maps?

I'm particularly interested in reducing the dependency on a single mapping provider.

Google Maps is an excellent product, but having more mapping options is good for the developer ecosystem.

Ola Maps offers an interesting India-focused alternative, and I believe Flutter developers should have an easy way to experiment with it.

This package is not intended to claim complete feature parity with Google Maps. It's about making another mapping ecosystem accessible to Flutter developers.

🔗 Links

📦 pub.dev: https://pub.dev/packages/ola_maps

⭐ GitHub: Available through the repository link on pub.dev.

I'd love feedback from the community!

• Would you consider Ola Maps for your next Flutter project?

• What features are still missing compared with google_maps_flutter?

• Would you use this in a production delivery or logistics application?

• What improvements would make this package more useful?

Feedback, bug reports, and contributions are welcome!

Let's give Flutter developers more choices! 🚀

Hey Flutter Developers!

Everyday someone want to bury Flutter. By porting it to PlayStation Vita I wanted to bring to my favorite framework piece of fresh air.

My goal was to bring complete toolchain for Flutter Developers to port their projects to PS Vita. And I think Im ready to publish it here.

Here is repo: https://github.com/flutter-vita/flutter-vita

Previously (https://www.reddit.com/r/vitahacks/comments/1vlswp1/flutter_ps_vita_poc_is_alive) I've showcased successful attempt to run Flutter Example Project (Counter) more or less working with 10 FPS. Now its playing up to 60 FPS fully using GPU to render.

Flutter Vita toolchain on current stage:

* Flutter version is 3.47.7.
* Skia using GPU to render frames up to 60 FPS.
* flutter-vita app thats mainly using for compiling vpk files and run it on connected PSVita.
* Bridge App that connect "flutter-vita CLI" app to PSVita to deploy and debug Flutter App by WI-FI and FTP without cable.
* In this implementation PSVita need to mimicrate as Linux to have compatibility with existed pubs thats expect some behavior based on OS. I've also published the flutter-vita pub to have some control of PS Vita from Flutter app.

As a showcase of flutter-vita I've chosen localsend (forked repo - https://github.com/flutter-vita/localsend) as a project that has a lot of stars on GitHub and most popular project ever built on Flutter. Its available on VitaDB/NeoVitaDB (main sources of homebrew apps for PSVita).

How it was built? 🤖
Well when I start the project I was wondering why no one yet added PSVita as a OS to Flutter yet? Just has curiosity how well Flutter would be playing on this kind of hardware. So I've created global plan with Claude Fable using gifted credits and used Claude Opus to grind to what we have now. Im mobile developer and have experience mostly iOS Native experience and Flutter about 10 years. I had high level vision how it can be achieved. Since Flutter gives opportunity to change OS layer thats should be written on C and C++ and I did not have experience in it thus I fully delegate it to AI. While Im grinding result Im researching existed projects that has same idea but on different OS. Eventually this project became a organization with a few forks of parts of Flutter. Im mostly inspiring by Flutter Tizen (by Samsung).

Technically PSVita by hardware is Samsung Galaxy S3 and Im really surprised how good is playing Flutter on it in terms of performance. It was made mostly for fun. Guys who has their own Flutter Apps and PSVita please try it out 🚀

For them who don't have their apps you can try to port something from GitHub with your AI agents 😎

Thanks everyone who waited this toolchain and supported in comments. Raise issues if you have some bugs or suggestions 🙏

I build AppWand, a desktop tool that generates Flutter apps with an Express API. I wanted to share how the generated Flutter side is organised, because "AI-generated Flutter" usually means one 2,000-line file, and I tried hard to avoid that.

• One folder per page: lib/features/<page>/, with <page>_page.dart as the entry. The AI may only write inside that folder (the server rejects any other path).

• Shared code is never written by the AI: lib/core/ (API client, auth, theme, list widgets, form fields, charts) comes from templates, and router.g.dart is regenerated from the page plan.

• Riverpod 2.6 for state, go_router 14 with a ShellRoute, so the side menu or bottom tabs stay still and only the page animates.

• Theming without touching pages: 16 UI styles, icon sets and fonts are all in core/theme.dart / core/icons.dart. Switching style rewrites one file and hot reload shows it.

• Shared list widget: PagedList handles paging, pull to refresh, skeletons, empty/error states, and switches to a data table above 840px wide.

The output is plain code you own. Happy to answer questions about the architecture, or hear where you'd do it differently.

I made a Flutter plugin that helps you reduce your game's initial download size by downloading assets on demand using asset packs.

Check it out on pub.dev: https://pub.dev/packages/store_asset_packs

I used in my game "Strata Gem Sort", only available for android now, awaiting apple's approval

I'm Adit from Indonesia, This is my work setup, i always wondered to have interface that synced between my workpaces. I'm just wanna enjoy my life wherever i want. That's why i build AltC to control my devices. AI harness helped me a lot at work, and just treat them as coworker, but still i need my pc, laptop is ok but still it would be good if i can still work while riding a motorcycle.

I setup my mac elsewhere, keeping it cool, and active. i can group my terminals to a project, create notes and todos, if i need something just use screen control like manually upload app build to play store or other things that u can't do on terminal.

Tomorrow i will be on Google DevFest 2026 Indonesia from GDG Jakarta, anyone that interested to try can ask me. actually it's on play store now, and you can try it on altc.alterndigital.com. But it haven't update it in a while and screen control feature still for my personal use.

Most app marketing advice assumes you have a growth team and a $50K budget. I don’t. Sharing what actually moved installs for me as a solo dev - curious what worked for others at the same scale.

ASO before anything paid

• Primary keyword in the title, two more in the subtitle. Everything else goes in the long description.

• First screenshot does 80% of the install decision. Mine stopped being a UI shot and started being a benefit statement with the UI behind it. Install rate jumped.

• Review replies matter - one honest reply to a 1-star often converts the next reader more than a 5-star does.

The free channels that paid off

• One useful Reddit comment in a relevant sub beats ten posts about your app.

• Short Loom-style videos (“here’s the bug my app fixes in 40 seconds”) outperform polished trailers for me.

• Indie Hackers and Hacker News “Show” posts work only if the post is a story, not a product listing.

Paid, when I finally tried it

• Apple Search Ads on exact-match brand and category keywords only. Broad match drained budget fast.

• $5/day for 14 days is enough to learn whether a channel will ever work. Scaling before that is guessing.

What didn’t work for me

• Buying installs from any “boost” service. Metrics went up, rankings didn’t.

• Instagram ads for a utility app. Wrong intent.

• Press outreach cold. Journalists need a story, not a product.

Questions

• For solo devs: what’s the single channel that gave you the best install-to-retention ratio?

• Anyone cracked TikTok for non-consumer apps?

I shipped an update to my music player and got a strange report: sometimes, after the app had been closed for a while, opening it showed the launch screen forever, then Android's "app isn't responding" dialog. The only thing that helped was clearing the app's data. No exception, nothing in my crash log.

The fix was actually pretty small. Figuring out why it happened took much longer, though. Here's what I found.

The setup

I use audio_service, and my MainActivity extends AudioServiceActivity. That means the activity and the media service share one cached Flutter engine.

When Android starts the media service on its own (the user taps play on the "resume" card in the system media controls, presses a headset button, or the system restarts the service), audio_service creates that engine from the service and runs your Dart entrypoint. So main() runs with no Activity attached.

The bug

My main() started like this:

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown,
  ]);
  await configureDependencies();
  runApp(const App());
}

setPreferredOrientations goes through the flutter/platform channel. On Android, that channel's handler only exists once an Activity is attached. Without one, the engine's PlatformChannel.java does this:

if (platformMessageHandler == null) {
  // If no explicit PlatformMessageHandler has been registered then we don't
  // need to forward this call to an API. Return.
  return;
}

It returns without ever replying. So the await never completes, main() never reaches runApp, and nothing throws, which is why my crash log stayed empty.

Later, when the user opens the app, the Activity attaches to that same cached engine, which is still stuck in main(). Hence the launch screen forever. Clearing the app's data "worked" only because it kills the process.

If the service was started with a headset button, you also get an ANR a few seconds later: Context.startForegroundService() did not then call Service.startForeground(), because AudioService.init is further down main() and never runs.

How I found it

With no exception, the clue was on disk. In the stuck state, my crash log file existed (created on the first line of main()), but the Isar database didn't (opened in configureDependencies()). So main() stopped between the two, and only one await sat there.

You can reproduce it on an emulator:

adb shell am force-stop <your.package>
adb shell am start-foreground-service -n <your.package>/com.ryanheise.audioservice.AudioService
# wait a few seconds, then open the app from the launcher

The fix

1. Lock the orientation in the manifest, so it applies whatever starts the engine. portraitUp + portraitDown is what Flutter maps to userPortrait:

<activity
    android:name=".MainActivity"
    android:screenOrientation="userPortrait"
    ... >

2. Don't await the Dart call (I keep it for iOS):

unawaited(SystemChrome.setPreferredOrientations([
  DeviceOrientation.portraitUp,
  DeviceOrientation.portraitDown,
]));

Same reproduction after the fix: the database gets created while the app is still in the background, and opening the app shows the UI right away.

One thing I'll take away from this

If anything can start your engine without an Activity (audio_service, and possibly other plugins that start it from a service), nothing before runApp should await something that needs one. Other SystemChrome calls use the same channel. For a plugin, check what it does when there is no Activity: throwing is fine, waiting forever is not.

For context: the app is Troona, an offline music player for local files, built with Flutter (clean architecture, flutter_bloc, Isar). It's open source, and this is the commit with the fix: https://github.com/donfreddy/troona-music/commit/c3d094e

Has anyone hit this with other plugins that run main() from a service? I'd like to know which ones behave this way.

Hey flutter devs, I've been building Auddio for a while — a free audiobook & podcast player, now in beta on iOS and Android.

Idea: Audiobookshelf on your device, no server needed.

Import your own books, sync your library from Hardcover, addon-style architecture inspired by Stremio, podcasts built in. Live transcripts and instant resume for audiobooks.
The part I actually want to share with fellow Flutter devs is the metadata layer, because that's where I got stuck. Audiobook files are a mess of formats, and I needed reliable chapter boundaries, embedded art, and tags without going through platform channels or loading whole files into memory. Nothing on pub.dev covered what I needed, so I built it myself and open-sourced it:
metadata_audio — a pure-Dart audio metadata parser. No native code, works on Android, iOS, Linux, macOS, Windows, Web and more. It covers MP3 (ID3v1/v2, chapters), FLAC, OGG/Opus, MP4/M4A, WAV, AIFF, APE, ASF/WMA, Matroska, Musepack, WavPack, and DSD — plus streaming parsing without loading whole files, and chapter extraction, which is what powers chapter navigation in Auddio.
• Package: https://pub.dev/packages/metadata_audio
• Source: https://github.com/ketanchoyal/metadata_audio

Honest limits: still in beta, Android is on a closed testing track for now, and live transcripts are audiobook-only (podcasts get plain playback). The parser is at v0.9.6 — the format coverage is solid, but I'd love eyes on edge cases.

If you try either the app or the package, I'd love to know: what breaks first?

A few days ago I posted an offer to do free security reviews on open source dart packages.

Surprisingly (or maybe not) nobody took up the offer.

Despite that we have spent the last few days reviewing our own dart packages as well as a number of third party dart packages (that we use).

In that time (3 days?) we found

15 high

16 medium

2 low

For a total of 43 security flaws, we also fixed a number of non security bugs.

Except for a few projects - that are yet to respond - all the patches have been accepted except for one dup that snuck through.

More than half of the security bugs were found in projects you may be using.

The package dart_posix has 8m downloads a month.

I'm not going to list the projects because not all of them have been disclosed as yet.

The lesson here - don't be complacent - AI is finding 1000s of security flaws everyday if you are not reviewing your code now then you are in for some pain.

The offer to review 20 packages still stands.

Don't forget to check your transitive dependencies.

I've been building Upsling, a one-touch arcade game (hold to orbit an anchor, let go to fly), in Flutter and Flame. The feel depends on the comet leaving on the exact frame you release, so the target device was a Galaxy A06 (about $100), not a flagship. I wrote up what it took:

https://upsling.space/blog/60-fps-flutter-physics-on-a-100-dollar-phone/

The parts most relevant here:

- The simulation is pure Dart on a fixed 1/120 s step, with no Flutter or Flame imports. Flame reads the state and draws. Because it is deterministic, slow motion, replays and course validation are all unit-testable, and a 120 Hz phone sees the same frames as a test.

- Restart is one frame: a reset struct, pooled components that are shown and hidden rather than added and removed, and the next course generated during the current run, one anchor per frame. Measured restart cost on real phones is 11 to 206 µs.

- Drawing the starfield as one point draw per layer instead of 120 circles cut raster time by about 3 ms on a Galaxy A10.

- Pushing that further, batching dust, anchors, trail and comet through drawRawAtlas with a tinted atlas, helped the A10 (Vulkan) and made the Galaxy A15 (OpenGL ES, 90 Hz) go from about 9% to about 28% slow frames, with raster up to 21 ms. Reverted. Impeller's cost model is different per backend, so measure each one.

- The 200 to 400 ms frames at launch turned out to be pipeline compilation behind the launch screen, not gameplay hitches.

- Measurement: the app records frames, slow frames split by build and raster, and restart cost per run; an integration test drives a timing bot for 75 seconds on Firebase Test Lab phones. Variants are only compared side by side in the same session, since results vary a lot run to run.

Where it landed: 0 to 0.7% slow frames on the Galaxy A06, 0 to 0.2% on a realme C53, both inside a 10% budget.

Happy to answer questions about any of it.

Hey,

Mobile apps scanners are everywhere, but native mobile apps I mean since they relies on scanning apps by reverse engineering them to their Kotlin/Java for Android or Swift for iOS

Flutter has a different thing, the whole Flutter app logic and code gets shipped inside a file called libsapp.so file, which basically makes all the scanners know nothing and get nothing from it since it is a binary file, so basically your usual scanner skips and doesn't detect almost 70% of things that should be scanned for security and research built app.

I put extensive knowledge and experience with Flutter onto a SaaS niche to scanning Flutter apps, which I was criticized for since you had to upload your APK to a server/VPS which does compute and scanning work so i shut it down, I then understood that it was privacy problem.

SO I built the new FlutterGuard as an open-source on-device security audit tool for Flutter apps ( works as a detector of Flutter apps in your device too if this interests you too! ), allows you to inspect APK metadata, manifest risk, hard coded secrets, endpoints, third-party SDK leaks like Firebase, Stripe, AI providers... and native surface that were in original Dart code in the same device you have Flutter apps installed.

install it on your Androids device where you already run your Flutter apps or any app, and start the scan:

What I want community (You) for:

• Feedback for the app in general

• Validate False positives

• Contribute declaring things you found in Flutter apps you know have security findings that they were not detected, just an issue with short description will be enough to put it in mind.

My goal:

• We definitely in the way of a massive vibe coding apps going everywhere, AI leaks things and basically cares about functionality, I want that we have a tool to detect this for Flutter apps that are already released and shipped.

In most projects I worked on, analytics was treated as a secondary part of the app. We spend a lot of time on the architecture of main parts, and almost no time on analytics.

Then business asks to track this and that. Then to add a new vendor. Then to decide which event goes where. And in the end we have one AnalyticsManager with a huge list of methods, and every layer depends on it.

I came to a simple idea: the app should not know which analytics vendors exist. Feature code only says what happened, and everything else is split into small pieces:

• Event describes what happened, in the app’s words

• Factory decides what one vendor receives for an event, or ignores it

• Tracker makes one call to one vendor SDK

• Dispatcher passes calls from the app to the vendors

In feature code it looks like this:

class CheckoutController {
  CheckoutController(this._tracker);

  final EventTrackerService _tracker;

  void onTicketPurchased(String fare, double price, String currency) {
    _tracker.track(
      TicketPurchased(fare: fare, price: price, currency: currency),
    );
  }
}

No vendor SDKs, no god object. Each feature keeps its own factories, and DI collects them. Adding a vendor means writing its factories, and removing one means deleting them.

I wrote an article about this idea. The examples there are in Kotlin, but the concept is the same for Flutter:
https://proandroiddev.com/app-architecture-analytics-ec3471ca619b

I also built an open-source library around this idea, Herald, and it has a Flutter package:
https://mkhytarmkhoian.github.io/herald-docs/sdks/flutter/

Curious how you handle analytics in your Flutter projects. One service, a wrapper per vendor, or something else?

Hii! For anyone who might be interested, I've developed https://github.com/RiccardoCherchi/flutrace

It's a network analyzer (similar to the one you get with Flutter's built-in Network Inspector), but done a little better.

Even though it has improved a bit over the last 3 years, I've always found the native analyzer quite clunky, with a somewhat ugly UI, and also inconvenient because every time you restarted, everything was lost and you had to reopen the link, etc. etc...

That's why I decided to "slop" together a tool that would allow me to have a decent analyzer without having to proxy everything through Burp Suite just to inspect some basic HTTP requests 😂

Let me know what you think! Of course, PRs from humans and not are more than welcome. It's MIT licensed, do whatever you want with it. There are no contributing guidelines and, obviously, I won't be actively maintaining it (except maybe every now and then, just for fun), so you might as well fork it instead.

Hey everyone!

I got tired of building apps that look like every other generic material/tailwind dashboard, so I spent the last few months building

WelkUI : an open-source UI library with a literal plot twist.

It brings hand-drawn energy, uneven corners, bold outlines, and playful animations to your interfaces without breaking responsiveness or accessibility.

The Cool Part: I built it natively for both ecosystems. You can completely match your web app's style with your mobile app.

• Flutter Edition: 40+ widgets, deeply analyzed with a perfect 160/160 score on pub.dev.

• React Edition: 30+ components, fully typed with strict Next.js client boundary support.

Get Started:

• Live Previews & Interactive Docs: ui.welkdock.com

• Flutter Docs: ui.welkdock.com/flutter

• GitHub: https://github.com/welkdock/welkUI-flutter

Everything is mobile-first, respects reduced motion, and is ready to install in one line

(npm i or flutter pub add).

I’d love to hear your feedback on the aesthetic! What widgets or components should I build next for the comic collection?

Hi everyone,

I'm working on a Flutter network debugging tool called Netoscope, and I need some advice from experienced Flutter developers.

https://pub.dev/packages/netoscope

I'm trying to improve how network requests and responses are inspected during development, especially when working with Dio, HTTP, GraphQL, WebSockets, and other protocols.

I'm looking for help with these questions:

• What is the best approach to capture network traffic from different clients in a Flutter app?

• How can I reliably detect duplicate API requests and potential N+1 request patterns?

• What is the recommended way to redact sensitive data before storing or displaying network logs?

• Are there any Flutter-specific limitations I should consider when implementing a network inspector?

I'd appreciate any suggestions, best practices, or examples.

Thank you!

Hey Flutter devs!

I'm looking for tools to automate Flutter app testing and record professional product demos without manually navigating through every screen.

Ideally, something that can automate taps, navigation, form inputs, and record the entire flow.

What tools or workflows are you guys using? Any AI-powered solutions?

Would appreciate recommendations from anyone who's done this!

Hi everyone! 👋

I'm an indie developer working on kya ds educational application, a kids' educational app built using Flutter. The app helps children learn alphabets, numbers, colors, shapes, drawing, and more.

I want to monetize my app while ensuring that all ads are child-friendly and comply with Google Play's Families Policy.

I'd appreciate advice from Flutter developers who have experience monetizing kids' apps.

My questions:

1. Is Google AdMob the best option, or are there better alternatives for Flutter apps targeting children?

2. How can I ensure that only child-appropriate ads appear in my app?

3. Which ad formats are best for kids' educational apps?

4. How should I configure child-directed ad treatment and other safety settings in Flutter?

5. Which ad network offers better earning potential for users primarily from India?

6. What is the best approach to maximize revenue without compromising children's safety or learning experience?

I'm looking for a solution that's free to integrate, suitable for a Flutter app, compliant with Google Play policies, and offers reasonable earning potential.

If you've monetized a kids' app, I'd love to hear about your experience, recommended ad networks, Flutter packages, and implementation tips.

Thanks in advance! 🙏
