bloc_library example: dependency between BLoC classes

[contfedorov]

bloc_library example contains direct dependency between FilteredTodosBloc and TodosBloc. It is directly not recommended in BLoC library documentation. Please fix it.

flutter_architecture_samples/bloc_library/lib/blocs/filtered_todos/filtered_todos_bloc.dart

Lines 12 to 25 in d898d13

	FilteredTodosBloc({required this.todosBloc})
	: super(
	todosBloc.state is TodosLoaded
	? FilteredTodosLoaded(
	(todosBloc.state as TodosLoaded).todos,
	VisibilityFilter.all,
	)
	: FilteredTodosLoading(),
	) {
	todosSubscription = todosBloc.stream.listen((state) {
	if (state is TodosLoaded) {
	add(UpdateTodos(state.todos));
	}
	});

Thanks! Yah, I just recently upgraded the examples to work with the latest version of Flutter, but I did not update the way the samples worked themselves.

You're right, since the sample was originally authored by Felix, the Bloc community has changed this pattern. I'll update it!

Flutter Todos sample prefers stream-based repository over future-based. Could you please follow future-based approach? Just to have different examples of the same app.
