Multiple blocs for better organization

[israelazo]

Hi Riberto.

I'm pretty new to flutter and this generic bloc provider works really well so far. I'm trying to organize my code into classes and different blocs, but i can't find a way to pass multiple blocs to my main class or widgets.

Something like:

final userBloc = BlocProvider.of<UserBloc>(context);
final productBloc = BlocProvider.of<ProductBloc>(context);

Do you think is possible?

Hi @israelazo, I'm not really sure to understand your problem but if you want to get access to several blocs in one widget your approach should work.

It's also usual to compose blocs. For instance, you may have a top level bloc called appBloc which contains an instance of several specific blocs.

Another thing I like to do is to provide a helper class with static methods to avoid being verbose when accessing differents blocs:

import 'package:generic_bloc_provider/generic_bloc_provider.dart' as provider

class BlocProvider {
  static AppBloc of(BuildContext context) => appBloc(context); //alias

  static AppBloc appBloc(BuildContext context) =>
      provider.BlocProvider.of<AppBloc>(context);

  static ContentBloc userBloc(BuildContext context) =>
      appBloc(context).userBloc;

  static ProfileBloc productBloc(BuildContext context) =>
      appBloc(context).productBloc;
}

Not sure if I answered your question but feel free to ask if not 😁

this wasn't really an issue, but I couldn't find another way to ask.
