emit method

@visibleForTesting @override void emit(TutorialComponentState state)

emit is only for internal use and should never be called directly outside of tests. The Emitter instance provided to each EventHandler should be used instead.

class MyBloc extends Bloc<MyEvent, MyState> {
  MyBloc() : super(MyInitialState()) {
    on<MyEvent>((event, emit) {
      // use `emit` to update the state.
      emit(MyOtherState());
    });
  }
}

Updates the state of the bloc to the provided state. A bloc's state should only be updated by emitting a new state from an EventHandler in response to an incoming event.

Implementation

@visibleForTesting
@override
void emit(State state) => super.emit(state);
