didChangeAppLifecycleState method
Called when the system puts the app in the background or returns the app to the foreground.
An example of implementing this method is provided in the class-level documentation for the WidgetsBindingObserver class.
This method exposes notifications from SystemChannels.lifecycle.

Implementation
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
super.didChangeAppLifecycleState(state);
// TODO didChangeAppLifecycleState often called multiple times, fix!
if (state == AppLifecycleState.paused) {
appLifecycleCurrentState = state;
_packUpPlayback();
}
if (state == AppLifecycleState.resumed) {
// Restore with playback state saved on native side
if (appLifecycleCurrentState == AppLifecycleState.paused) _restore();
}
}
