In AngularDart 3.0.0 EventEmitter is deprecated. So, how to send event from child component to parent?
Before update it is looks like:
@Component(
selector: 'my-test',
templateUrl: 'test.component.html'
)
class TestComponent {
@Input()
String name = '';
@Output()
EventEmitter<String> onNameChange = new EventEmitter<String>();
}
...
onNameChange.emit('New Name');
...
Now I need use Stream and StreamController. Can someone give an example?
Just use a normal StreamController
final _onNameChangeController = new StreamController<String>.broadcast();
@Output()
Stream<String> get onNameChange => _onNameChangeController.stream;
.broadcast is optional. It is required to allow multiple subscribers.
