AnimationLocalListenersMixin mixin Null safety
A mixin that implements the addListener/removeListener protocol and notifies all the registered listeners when notifyListeners is called.
This mixin requires that the mixing class provide methods didRegisterListener and didUnregisterListener. Implementations of these methods can be obtained by mixing in another mixin from this library, such as AnimationLazyListenerMixin.
