Fear Of StatefulWidget is becoming the norm in Flutter?
I swear to God a question about getting rid of StatefulWidget appears at least 10 times a month in this subreddit.Idk why some of you folks scare of it that much, it's just a Widget. What I'm trying to blame is either crappy tutorials or your narrow understand that makes StatefulWidget becoming a Villain in Flutterverse. Which it's all about setState and we have to get rid of it rebuilding the whole widget?Come on, StatefulWidget exists does not exist to do just that, what are you gonna do if you wanna messing around widget lifecycle when you only have StatelessWidgets?If you want local scope state management, Listenable/Builder out there for you, refactor a StatefulWidget to StatelessWidget doesn't help a bit of performance-wise at all.The problem is, some ppl are relying too much on Tutorials which are not official sources of truth to learn programming. When you want to learn about sth, for example, a Widget, your best pal is Flutter Offical Doc flutter.dev.Open your IDE, reading the docs and dive into the Widget itself and you will learn A TON OF INFOs in there. Because almost all of the Tutorials out there just give you spaghetti noodles that do not help you in the long run. Screw them! They are a kind of disease in this programming community! Getaway from them for God's sake!That why I'm freaking mad about it, the time you ask for a question and then waiting for responses is far more wasting than a proper search.

BLOC API Call Question
Hello! I am working on a ShuttleTracker app for my school. I receive the data from a JSON API that updates the geolocations of the shuttles. I am currently using the BLOC pattern in my app and I can retrieve the updated data every time I press the 'restart button'. What is the best way, using the BLOC pattern, to automatically receive the API change. Maybe periodically running the event every 1 min? I'm not quite sure. Thanks.

Here's A Flutter Boilerplate(Starter Kit) with BLoC pattern, splash screen, sample pages, Google Admob ready
Building a Flutter app is simply amazing! Even more amazing is the fact that you can reuse your code in multiple projects! But there are times you simply need to kick-off a fresh project without having to copy from another project.So I wrote a simple boilerplate which I could easily git clone and simply kick-off! Having built 3 professional apps with it, I've open-sourced it so anyone stuck can simply kick-off and build their app.Happy coding everyone. (PRs are very welcome btw)Github Link - Flutter Boilerplate

Why did Flutter choose Dart?
Why did Flutter go with Dart instead of TypeScript or JavaScript for example?I enjoy flutter but do you see flutter being supported long term and not being abandoned by Google like some other projects they had back in the days?

New post on /r/flutterdev subreddit:

Is anyone REALLY using Provider in a non-trivial app with async dependencies?
(There are older threads with similar titles, like this one with no conclusive or interesting answers.)I am trying to use scoped DI in a fairly complex app, so I chose Provider.The app requires a variety of "global" services in order to run, so the registration pattern goes along these lines:```dart runApp(MultiProvider( providers: [ //... ], child: MyApp(), ));class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { if (context.watch<DataLoading>().value) { return const CircularProgressIndicator(); } return MaterialApp( //... ```Pretty much like u/bizz84 does here.Most of my services require async initialization (some of them open Hive boxes), for which FutureProvider is needed. But they also depend on other asynchronous services, which require the use of ProxyProvider and the update callback.FutureProxyProvider does not exist and Remi wasn't able to come up with an API for this usecase.So something as simple as:dart int a = await Future.value(42); num b = await Future.value(a + 0.2); String c = b.toString();turns out to be hair-pulling in the Provider world.dart MultiProvider( providers: [ FutureProvider<int>(create: (_) => Future.value(42)), FutureProvider<num>(create: (context) => Future.value(context.watch<int>() + 0.2)), ProxyProvider<num, String>(update: (_, b, __) => b.toString()), ](The updated value of num never reaches the String provider.)Sure, I could use await like the following:```dart runApp(CircularProgressIndicator());// do ALL async work here await getApplicationDocumentsDirectory(); await service1(); await service2(); await service3();runApp(MultiProvider(syncSetup(...), child: MyApp())); ```but this would not be the Flutter way, as Remi put it: "Providers will require you to always be ready to draw.". This means that your data loading widget, or CircularProgressIndicator() should be in the build method of your app widget.u/remirousselet is a blessing with all his fantastic open source work, but practical and real-world examples of Provider is something I've yet to see. "Anyone using Provider in production?" doesn't add much at all.Is anyone using it in this fashion and can share their async setup? Any good alternative or perhaps some resource I have missed?
