Angular Dart component events

Question

I am trying to pass custom events from a component to its parent component/controller

confirm.html

Answer 1

Based on the answer from Günter i built this working example:

@Component(
    selector: "confirm-component",
    templateUrl: 'component/confirm.html',
    useShadowDom: false,
    publishAs: "ctrl"
)

class ConfirmComponent implements ScopeAware {
    Scope scope;

    void yes(){
        scope.emit('confirm', 'yes');
    }

    void no(){
        scope.emit('confirm', 'no');
    }
}

@Component(
    selector: "my-component",
    templateUrl: 'component/my.html',
    useShadowDom: false,
    publishAs: "ctrl"
)
class MyComponent implements ScopeAware{

    void set scope(Scope scope) {
        Stream mystream = scope.on('confirm');
        mystream.listen((event){
            print('confirmed: ' + event.data);
        });
    }
}
