Event Transformers #
bloc_concurrency provides an opinionated set of event transformers:
concurrent - process events concurrently
sequential - process events sequentially
droppable - ignore any events added while an event is processing
restartable - process only the latest event and cancel previous event handlers
Usage #
import 'package:bloc/bloc.dart';
import 'package:bloc_concurrency/bloc_concurrency.dart';
sealed class CounterEvent {}
final class CounterIncrementPressed extends CounterEvent {}
class CounterBloc extends Bloc<CounterEvent, int> {
CounterBloc() : super(0) {
on<CounterIncrementPressed>(
(event, emit) async {
await Future.delayed(Duration(seconds: 1));
emit(state + 1);
},
/// Specify a custom event transformer from `package:bloc_concurrency`
/// in this case events will be processed sequentially.
transformer: sequential(),
);
}
}
