BLoC users, how do you scope your blocs ?
I have been using BLoC for more than 2 years on side projects, but I never used it in a real professional project, how do you scope your BLoC logic ? Do you scope that per use case, per page or per widget ? Something else ?I’m really curious and I’m always hesitant when starting a new project, I have a Android background with a strong experience of MVVM and MVP using the Clean Architecture principles as much as I can.Usually my ViewModels or my Presenters are scoped based on the page (screen) purpose, so it includes everything needed for that page and it exposes 1 or a few ViewStates (depending on the layout and fragments structure).If I create feature scoped blocs, I start to do over engineering while trying to make it as reusable as I can, if I do page scoped blocs, it becomes heavy and hard to manage.Any advice or experience is welcome :)View Poll

Coming back from a long break, what have I missed?
Hi! I've taken a break from flutter app development for about a year and a half, before null safety was introduced. Starting to develop apps again. What are some of the cool new features been added since I've been away?

New `SharedAppData` widget
Looking through Flutter's commit messages, I noticed that a new widget was added to Flutter master which allows to easily share data between widgets. In this respect, it is similar to the hundreds of other state management libraries.Here's a simple example using the widget. By default, the MaterialApp already provides a SharedAppData scope to the context. Descendants of that widget can then share data identified by some key. I chose the class object Counter in my example. The getValue call will automatically register the provided context as a dependency and therefore a rebuild is trigged if the value is changed.

class Counter extends StatelessWidget { const Counter({Key? key}) : super(key: key); @override Widget build(BuildContext context) { final count = SharedAppData.getValue(context, Counter, () => 0); return Scaffold( body: Center(child: Text('$count')), floatingActionButton: FloatingActionButton( onPressed: () => SharedAppData.setValue(context, Counter, count + 1), ), ); } } 

Of course, it is possible to wrap that method calls to abstract the key into something that looks like a "Provider". Here is my 3 minutes adhoc "framework":

class Provider<T> { Provider(this.create); final T Function() create; T watch(BuildContext context) => SharedAppData.getValue(context, this, create); void Function(BuildContext) set(T value) => (context) => SharedAppData.setValue(context, this, value); void Function(BuildContext) update(T Function(T) update) => (context) => set(update(watch(context))); } final counterProvider = Provider(() => 0); 

The build method now looks a bit nicer:

Widget build(BuildContext context) { return Scaffold( body: Center(child: Text('${counterProvider.watch(context)}')), floatingActionButton: FloatingActionButton( onPressed: () => counterProvider.update(increment)(context), ), ); } 

The new widget isn't a solution for everything but a nice addition and enough for small and medium sized application, I think. Notice that the above approach isn't as efficient as provider or riverpod would be, but it doesn't need external libraries and might be good enough.

How do you handle errors?
I recently started to work with flutter and in the last days I struggled a lot to find some information about handling errors and displaying messages to users.I am right now using riverpod with statenotifier and I was thinking a good way to do it is to create some intermediate state classes like StateInit, StateLoading, StateSuccess, StateError and in every screen to check the state instance and render a widget accordingly, but it is getting pretty repetitive since I want to display the same error type or loading, but with different messages.Anyway, how do you handle your app errors?

Pro Tip: enableDithering property
My gradients weren't looking smooth, so i googled it and came across this stackoverflow answer: https://stackoverflow.com/a/64807773/13972151It made my gradients way more smooth, color stops are way less visible now. I saw that this property isn't mentioned much; so i thought it could be useful to some.

HTTP GET and POST are very slow in IOS compared to Android
I recently knew about a problem in Flutter in IOS physical devices, which is mainly (HTTP GET and POST are very slow in IOS compared to android) I'm starting a project that depends heavily on the back-end, so I'd like to hear from people having the same case and went to production. Do you have this issue? Is it fixed in Flutter 2.5?

What are common practices in Flutter
Atm, I'm one month into Flutter and as stated in the title, I would like to know, what are the best or common practices in Flutter regarding things like the project structure, files naming, placing widgets as functions etc. Also how do you decide if u want to use stateless or statefull widget. How do you decide when to extract a widget to a separate file and inject/import it where & when needed.I haven't really watched any tutorials or taken any courses when learning Flutter, I mostly followed Flutter documentation as much as I could.

Flutter State Managers: Do big companies/projects rather use GetX, BLOC, or Provider?
Hi, I'm new to flutter and I want to know which state manager is more useful to learn. I've had some experience in all 3, but not sure what big companies or projects use. Or do they use a combination?Do they use the Provider package cause its the most popular one? Or do they use BLOC, which is complex for beginners. Or do they use GetX which I don't know why but I have seen more Youtube tutorials using it nowadays.Thanks!
