Examples of BLoC Usage

A compilation of commented Flutter starter incrementer app examples, that uses BLoC.

Implementations

• Local Instance: This example uses a plain local instance, which can be good enough for some situations.

  final incrementBloc = IncrementBloc();

• Ancestor Provider as Stateful Widget: A generic bloc provider (code by Didier Boelens) can instantiate any BLoC that implements the provider. It can then be accesed like:

  IncrementBloc incrementBloc = BlocProvider.of<IncrementBloc>(context);
