didChangeAppLifecycleState method

@override void didChangeAppLifecycleState(AppLifecycleState state)

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);
  if (state == AppLifecycleState.paused) {
    // Pause all video players when the app is paused
    for (var i = 0; i < videoPlayerControllerList.length; i++) {
      videoPlayerControllerList[i].pause();
    }
  }
}
