bloc

问题 I am trying to create a BLOC which depends on two other time based bloc and a non-time based bloc. What i mean with time based is, for example they are connecting a remote server so it takes time. It's working just like this: Login (It's of course taking some time) If login is successful Do another process (This is something takes time also. It returns a future.) After login and another process finishes, let the page know it. My BLOC depends on these three: final UserBloc _userBloc; final

问题 I am trying to implement bloc pattern in rxdart . I am trying to build todo app type of app . I implemented showing all items in list but what I want is not to show completed and uncompleted items in different part . However I am not able to filter the items based on completed on rxdart . import 'package:rxdart/rxdart.dart'; import '../models/ShoppingItem.dart'; class ShoppingItemBloc { final _shoppingItems = BehaviorSubject<List<ShoppingItem>> (seedValue: []); Observable<List<ShoppingItem>>

问题 I am a beginner in Dart language development. I try to create a sample flutter application BLOC pattern inspired by this GitHub repo, but I got some error message related to the class inheritance. I am already familiar with the inheritance and superclass and subclass programming in the dot net C# language. But in the case of the dart, I need some advice. Here is my code: class UserRegBloc extends Bloc<UserRegEvent, UserRegState> { UserRepository userRepository; UserRegBloc({@required
