LifecycleEventObserver
public fun interface LifecycleEventObserver extends LifecycleObserver
Interface for receiving any Lifecycle.Event state changes.
If a class implements both this interface and DefaultLifecycleObserver, the methods of DefaultLifecycleObserver are called first, followed by onStateChanged.
Note: If a class implements this interface and also uses the deprecated androidx.lifecycle.OnLifecycleEvent annotations, those annotations are ignored.
