Usage #
1 - Create a provider class that is going to gathering all BlocProvider annotation:
IMPORTANT: Do not forget to add: part 'provider.g.dart';.
import 'package:dash/dash.dart';

part 'provider.g.dart';

@BlocProvider.register(MySampleBloc)
@BlocProvider.register(MyOtherBloc)
abstract class Provider {}

2 - Extends all your bloc class from Bloc. It will allow you to override dispose method.
IMPORTANT: All bloc class must has an instance() function that returns the instance of the bloc class as bellow.
class MySampleBloc extends Bloc {

@override
dispose() {
//close all streams
}

static Bloc instance() => MySampleBloc();

}

class MyOtherBloc extends Bloc {

@override
dispose() {
//close all streams
}

static Bloc instance() => MyOtherBloc();
}

3 - Run build_runner, it will generate the provider.g.dart class that you added as part on your provider class.
On project directory run on terminal:
pub run build_runner build
For flutter is:
flutter packages pub run build_runner build
Note: If you encounter a conflict error, please add the --delete-conflicting-outputs argument to your command:
flutter packages pub run build_runner build --delete-conflicting-outputs
4 - Finally you can get your bloc class instance from wherever you want, example:
@override
Widget build(BuildContext context) {
final _bloc = $Provider.of<MyOtherBloc>();

return Container();
}

@override
void dispose() {
$Provider.dispose<MyOtherBloc>();
super.dispose();
}
