Better way to convert angular animation callback into observable?

I have an angular animation, that has a callback when it completes:



<section [@routerTransition]="getAnimation()" (@routerTransition.done)="transitionEnd($event)">
</section>


I'm currently handling that event, and emitting from an EventEmitter:



private transitionCompleted$: EventEmitter<null> = new EventEmitter();

transitionEnd() {
this.transitionCompleted$.emit();
}


transitionCompleted$ is an observable (EventEmitter is a subclass of observable) that emits when the transition completes.



Is there a better/more straightforward way to convert that callback into an observable?



What I don't like is having to handle that event, only to create a new event.



Something like this.transitionCompleted$ = @ViewChild('@routerTransition').done ...

          No, unfortunately there is no better way to do that at this point in time. They are currently working on a solution.
