MultiBlocProvider
Hello,I'm trying to use the new MultiBlocProvider (instead of old nesting BlocProvider) from package bloc​I had success with the old method but I can't adapt to the newWhen I click on the button I want to open a form CategoryFormDialog() , this form must have access to the bloc so I put him in the child of the MultiBlocProviderBut all I have is the famous error "BlocProvider.of() called with a context that does not contain a Bloc of Type CategoryBloc.No ancestor could be found starting from the context​If you have an idea it would be cool !class _MyHomePageState extends State<MyHomePage> {Widget build(BuildContext context) {return Scaffold(appBar: AppBar(),body: MultiBlocProvider(providers: [BlocProvider<CategoryBloc>(create: (BuildContext context) => CategoryBloc()),],child: ListView(children: <Widget>[FloatingActionButton(onPressed: () {showDialog(context: context,builder: (BuildContext context) => CategoryFormDialog(),);},child: Icon(Icons.add),)],),));}}

Flutter build process (preventing conflicts within dependencies, etc)
Does anyone know of an overview of the flutter build process? How it works, what runs first, in what order dependencies are compiled, how conflicts are resolved? Understandably, there are a ton of moving parts given what flutter offers. Especially if you start using plugins. Some of those plugins might call other native specific plugins, and so on. Each of these modules can have different build "requirements".List of moving parts as far as I can tell:build tools/processes used:pub (dart)gradle (android)cocoapods (apple)​uses Android X (yes/no)flutter SDK version range​gradle versioncompileSdkVersionminSdkVersiontargetSdkVersion​swift_versionios.deployment_targetplatform(honestly not sure what these 3 are but i've seen them in different places)So, as far as I can tell, (1) your flutter app, and (2) each it's dart/pub packages, and (3) all of their gradle/cocoapods dependencies could have their own and potentially conflicting settings.How much do we have to worry about this?There's no way that you can easily catalog each and look for conflicts.Which one takes priority? What happens when there are conflicts? For instance, what if my app's minSdkVersion is 19, but a dart/flutter plugin calls an android dependency that requires version 21? Would my app still compile (what about install and run)? What happens when it runs on a device running 19 that tries to use functionality provided by that plugin (not available until 21)?All is great now that I have my app running on my samsung s9 and iphone X for testing, but how in the world can I be sure there aren't some problems that would happen on other devices in the wild (with different OS versions, etc). I know I could theoretically create emulators for each OS for android/ios, but still i dont if that's enough to truly test for this.I think I could rest better understanding the role that each of these technologies play and how to be safe to ensure there are no conflicts.Thanks!

VSCode shortcut/extension for autocompleting parameters?
Sometimes when I watch flutter tutorials the youtuber presses a shortcut and an small popup with all the parameter options comes up, they are able to scroll to the option they want and click on it.This is similar to the "parameter hints" shortcut but not the same.As a follow-up, sometimes a parameter takes an implementation of an abstract class. Whats a quick way to search up all implementations of that abstract class in the flutter sdk.For example, im using the charts_flutter package, and want to specify a TickProviderSpec, but instead of the base tickproviderspec im supposed to specify a class which implements it. I want to know all the implementations of that class, since sometimes the implementation doesn't have the base class as part of its name autocomplete doesnt help.

What is considered as self promotion?
The rules state that "Self promotion must be only 50% of your posts".
As I find it useful to share StackOverflow answers I wrote, I am wondering if that is considered as self promotion. The idea is that sharing knowledge like this might answer questions that potentially many others are asking themselves.
However, I do not want to infringe any community guidelines either - so what should I do?

iOS apps have the ability to have iMessage apps within the default iMessage app that Apple provides with all iPhones. An example of this would be a simple sticker app that you send stickers to your friends. Is there a way to do this with flutter?
