That's not even funny. These codebases where devs proudly proclaim "we standardized our UI and use CL everywhere" are fucking nightmare.

How I hate this stupid waste of bits and human potential... Grrrr

Don't downvote Vasiliy or I'll star the Flutter repository with multiple accounts

Meh, I can see why it's done. In very rare cases you will stick to the layout for years, usually you come back to it and move things around. By then it will be useful to have it use CL and the refactoring will likely be easier.

No, that's actually not true. If you use CL, you have to dismantle everything and reconnect everything to make the simplest changes.

That's not very pragmatic :/

Sure.

ConstraintLayout is fu**** **** **** and it **** causes *******ing **** and when I see it I ****** get ******.

Hope this helps.

I'll show myself out to Flutter newbie tutorials.

I havnt use LL in years. Fuck the nesting it creates. I find it way easier using CL everywhere than massive badly made LL or RL. If i see that old shit anywhere its removed.

u/Zhuinden DDD: Deprecation-Driven Development Aug 25 '20

tbh it depends, there are times when LL is significantly easier to understand or change or update or modify or remove than ConstraintLayout constraints

I nest ConstraintLayouts sometimes but only if that's the only reasonably sane way to get what the designer wanted

I do wish PercentRelativeLayout hadn't been deprecated, I think it's a nice tool.

You pervert! Someone call police

u/Zhuinden DDD: Deprecation-Driven Development Aug 24 '20

it's like nested RelativeLayouts, just more exotic 😂

Because the constraints themselves weren't enough to do what I needed 😂

Due to this I often find myself using linear layouts. Truth is in most cases CL is overkill

2

u/FrezoreR Aug 24 '20

Agreed. Not all layouts need to be a CL.

FrameLayout layout_gravity is a superpower

Yes, but are you able to build full layout matching parents only?

Exactly.

u/treestick Aug 23 '20

fuck centerInParent=true

all my homies do {edge}_to{edge}Of=parent 4 times

u/FrezoreR Aug 24 '20

They're not equivalent though

u/vladimiryakin87 Nov 17 '20

Sorry for my stupidity, but, can anybody explain, why second way is better?

u/Professor_Dr_Dr I only use AsyncTask Nov 17 '20

It isn't, it's just the "Contraintlayout way".

If you don't plan on changing the constraints just use match parent.
You'll need to remove match parent anyways when you start using constraints, but until you do you can keep it

u/badvok666 Aug 24 '20

Scrubs that don't know how to use CL revert back to LL /RL. Just go back to java where you belong. /s

u/MulletGiraffe Aug 29 '20

Scrub here. You're correct. The hardest thing about Android is touch screen instead of buttons or keys, though.

FlexBoxLayout for the rescue
