Bluetooth controls don't trigger onPlayerStateChanged event on IOS

[ozz-rjq]

Basically, I have in-app play/pause controls, which I'd like to animate using animated button in a stateful widget once player's state is changed.

Widget code:

audioPlayer.onPlayerStateChanged?.listen((state) {
      if (state == AudioPlayerState.PLAYING) {
        _controller.forward();
      } else if ((state == AudioPlayerState.PAUSED)) {
        _controller.reverse();
}

Everything works great except the bluetooth controls on ios. For example, when I pause the remote audio by headphone controls, seems like it doesn't trigger onPlayerStateChanged and the in-app controls stay the same (but the actual audio is paused). Is it possible to intecept that events?
