Provider: Using MultiProvider

[MaxTenco]

Hi, why do I have the following error when I use the MultiProvider?

I/flutter (12486): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
I/flutter (12486): The following assertion was thrown building MyHomePage(dirty, dependencies:

I/flutter (12486): Tried to use Provider with a subtype of Listenable/Stream (A).
I/flutter (12486):
I/flutter (12486): This is likely a mistake, as Provider will not automatically update dependents
I/flutter (12486): when A is updated. Instead, consider changing Provider for more specific
I/flutter (12486): implementation that handles the update mechanism, such as:
I/flutter (12486):

I/flutter (12486): - ValueListenableProvider
I/flutter (12486): - StreamProvider

I/flutter (12486): Alternatively, if you are making your own provider, consider using InheritedProvider.

`void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MultiProvider(
providers: [
Provider(create: (_) => A()),
],
child: MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(),
),
);
}
}

class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
final provider = Provider.of(context);

return Scaffold(
  appBar: AppBar(
    title: Text('Test'),
  ),
  body: Text(
    'test',
  ),
);

}
}

class A with ChangeNotifier {}`

+1
But I also see you missed the type.
Type t = Provider.of<T>(context);

The exception clearly states what is happening.

You used Provider when you likely wanted to use ChangeNotifierProvider

Sorry, but I don't understund.
If I insert single Provider like this:
return ChangeNotifierProvider( create: (_) => A(), child: ...

It works, but with MultiProvider, I have that message.
Why I have to use ChangeNotifierProvider? The documentation tell me tu use Provider:
MultiProvider( providers: [ Provider<Something>(create: (_) => Something()), Provider<SomethingElse>(create: (_) => SomethingElse()), Provider<AnotherThing>(create: (_) => AnotherThing()), ], child: someWidget, )

[rrousselGit]

The type of provider that you want to use depends on what the object you want to provide is.

ChangeNotifiers uses ChangeNotifierProvider
Streams uses StreamProvider
And so on
