bloc_abstraction #

Simple abstraction for Flutter's BloC pattern implementation

Create BloC #

Create a BloC extending BlocBase

class CounterBloc extends BlocBase {
  void dispose() {
    // TODO: implement dispose

Use dispose() method to close your streams and cancel your StreamSubscription

Using BlocProvider #

Create a BlocProvider like this by passing bloc and widget

class HomeView extends StatelessWidget {
  final bloc = CounterBloc();

  Widget build(BuildContext context) {
    return BlocProvider(
      bloc: bloc,
      child: Scaffold(
        appBar: AppBar(
          title: Text("Title"),
        body: Info(),

That will grant you to get bloc inside the widget tree anywhere

class Info extends StatelessWidget {
  Widget build(BuildContext context) {
    final bloc = BlocProvider.bloc<CounterBloc>(context);
