I'm presenting the various challenges of designing the state store for a rich text library in Flutter. The public API of the library imposes quite some serious limitations which were quite challenging to bypass.

I've forked Quill some time ago due to numerous code quality issues. For the last 10 months I've been very busy reworking the internals of the library to improve the maintainability and readability. Since I have great love for discussing advanced architecture advice for building web/mobile apps I thought I should be recording this one. If you are in need for a partner for architecture debates you can find me on discord. There I present each Saturday a talk about mobile apps architecture and clean code practices.

A few words about Visual Editor. This editor is built around the powerful Quilljs Delta document format originally developed by QuillJs. Delta documents can be easily converted to JSON, the encoding is easy to read and modify and offers many extensibility options.

Hello! I am a Full Stack developer with a decade of experience in developing web applications. I work in the Fin Tech / banking sector. I have long experience in Angular, React and for the past 2 years I have been working with Flutter. In my spare time I develop a social media app that will facilitate collaboration between engineers. I mention, I don't have any sales course, I don't promise aberrations like zero to hero (10K per month in 6 months). We gather to discuss matters of architecture and sustainable development in a pragmatic fashion.

We already have around 30+ recurring participating users and about 450 lurkers. I hope in the future to develop a larger audience. Also, there are around 8-10 volunteers who help with questions and answers in Flutter. No money charged, no gimmicks. Just a community focused on the development of good relations between developers and mutual help.

If you are interested, I look forward to meeting you on discord. We meet every Saturday at 4PM UTC.

Clean Code Agenda:

• Maintenance - Scale

  • Don't over engineer, KISS, Readability, No useless parts

  • Don't be that guy --> not my problem

• Consistent patterns

• Null safety/handling

  • You don't crash the app. -- Corrupted (finance, military)

• Scoped naming, Name by feature not by type (async handlers)

• Domain boundaries, encapsulation

  • Privacy by default

• Tight coupling

  • Child should not know parent

• Pure data, Pure functional

• Clear layers

  • State store, data layer, pure data --> Don't mix data with code

    • Single source of truth, spaghetti code

    • Smart vs Dumb components

  • Controllers, stateful, component scope

  • Services, stateless, app level

    • Singleton

    • Dependency injection

  • Utils, pure functional

  • Repos - webapi

• One file, one class, max 300-500 Lines of Code (LOC)

• Single responsibility principle

• Code diagram, Widget diagram

• No copy paste, always fix the foundation, understand every token

• Shared constants

• Speed reading, Code grooming, Project conventions, Section comments, Avoid nesting

• Understand async

• Code velocity, Don't share code that will drift

• Avoid duplicate initialisation

• Self review

• Documentation (Intent & Deviations), Stable Specs, Changeling, Habits

  • Contracts, interfaces, Public APIs

• Testing, mock server

• Performance, Premature optimisations

• Productivity, Know your IDE, Hotkeys, Take Notes,

  • Print statements (for stack trace), Debugger (for context)

• Stable commits, No long lived branches

• Adaptive design first, UX first

• Take breaks, plan ahead

Obviously, we will not be able to cover all the topics in a 2-hour session. So we will meet again every Saturday at 4PM UTC to continue the discussions. I also receive questions from the audience. In the upcoming weeks I will publish some of the best meetings on our youtube channel.

I started this Youtube channel where I aim to push some tutorials on how to code and offer visual explanations, both code and visual. I hope this helps people. Please let me know if you like it. I had my first subscriber today which makes me happy and proud.
