mapEventToState method
Must be implemented when a class extends BidirectionalBloc.
mapEventToState
is called whenever an event is added and will convert
that event into a new BloC state. It can yield zero, one or several states
for an event.
Implementation
@override
Stream<FastMediaLayoutBlocState> mapEventToState(
FastMediaLayoutBlocEvent event,
) async* {
if (event.type == FastMediaLayoutBlocEventType.changed) {
var mediaType = event.payload as FastMediaType;
yield currentState.copyWith(mediaType: mediaType);
}
}
