void emit(
  1. State 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.

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.


void emit(State state) => super.emit(state);
