provider to riverpod with param about riverpod

I mean, there's likely a different way to do what you want.
But I don't know your architecture.

Local state is not supported by providers.

What is your use-case in creating the ChangeNotifier locally like that?

EditQuestionScreen build before firebase fetch and deserialize. Actually I just need to know, can I create global provider with widget params in riverpod?

Like this

class AHookWidget extends HookWidget {
  AHookWidget({this.question, this.answers});

  final QuestionModel question;
  final List<AnswerModel> answers;

  // i dont want local variable like this, i want global
  final aProvider = ChangeNotifierProvider(
      (ref) => QuestionProvider(question: this.question, answers: this.answers));

  @override
  Widget build(BuildContext context) {
    final provider = useProvider(aProvider);
    return Container();
  }
}

class ASubHookWidget extends HookWidget {

  @override
  Widget build(BuildContext context) {
    final provider = useProvider(aProvider);
    return Container();
  }
}

No you can't

I'm sorry to hear that, thank you for your help anyway 😊

may be stupid but like this

onPressed: () async {
  QuestionModel question = await api.getQuestion();
  List<AnswerModel> answers = await api.getAnswers();

  MaterialPageRoute(builder: (context) => 
    EditQuestionScreen(question: question, answers: answers));
}

class EditQuestionScreen extends StatelessWidget {
  EditQuestionScreen({this.question, this.answers});

  final QuestionModel question;
  final List<AnswerModel> answers;

  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider(
        create: (context) => QuestionProvider(
            question: this.question,
            answers: this.answers),
        child: Container());
  }
}

Put the questions and answers inside a provider
Then you will be able to put your ChangeNotifier in a provider too

Ok, i will do that, the problem will be solved that case. Thanks again, you saved me.

I think ScopedProvider is the solution.

final scopedProvider = ScopedProvider<String>((_) => throw UnimplementedError());

class AWidget extends HookWidget {
  AWidget({@required this.value});
  final String value;

  @override
  Widget build(BuildContext context) {
    return ProviderScope(
      overrides: [scopedProvider.overrideWithValue(this.value)],
      child: BWidget()
     );
  }
}
class BWidget extends HookWidget {
  @override
  Widget build(BuildContext context) {
    final providerValue = useProvider(scopedProvider);
    return Text(providerValue);
  }
}
