Bloc: Unable to retrieve Bloc from context in child widget

[franagu]

Describe the bug
I may be missing something here, but my understanding is that declaring a Bloc in a parent widget's context should make it available to the subt tree. It does not seem to be working for me. I get the error

BlocProvider.of() called with a context that does not contain a Bloc of type CreateFormBloc

Parent Class:
`class ScreenWrapper extends StatelessWidget {
ScreenWrapper({Key key}) : super(key: key);

@override
Widget build(BuildContext context) {
return BlocBuilder(
builder: (context, state) {
if (state is LoadingState || state is InitialState || state is SavingState) {
return Center(child: CircularProgressIndicator());
}
if (state is LoadedState) {
return AScreen();
}
if (state is CreateRequestedState) {
return BlocProvider(
create:(BuildContext context) =>
CreateFormBloc(repository: RepositoryProvider.of(context)),
child: CreateScreen(),
);
}
if (state is SearchState) {
return SearchScreen();
}
}
}
`
In the CreateScreen, using BlocProvider.of fails with the error. BlocProvider.of() called with a context that does not contain a Bloc of type CreateFormBloc

I'm not sure what I'm missing here.

Hi @franagu 👋
Thanks for opening an issue!

It looks like you're not accessing the repository correctly. You need to specify the type of repository when you perform the lookup RepositoryProvider.of<MyRepository>(context),

Also make sure you're providing the bloc type BlocProvider.of<CreateFormBloc>(context).

Let me know if that helps!

Thank you! Was missing the proper declaration of the Repo Provider, also nested the CreateScreen in another widget.
