LifecycleEventObserver

public fun interface LifecycleEventObserver extends LifecycleObserver

Class that can receive any lifecycle change and dispatch it to the receiver.

If a class implements both this interface and androidx.lifecycle.DefaultLifecycleObserver, then methods of DefaultLifecycleObserver will be called first, and then followed by the call of LifecycleEventObserver.onStateChanged

If a class implements this interface and in the same time uses OnLifecycleEvent, then annotations will be ignored.
