  _onTimebasedPlayerStateChanged ??= timebasedStateChannel.receiveBroadcastStream().map((dynamic event) {
    final state = ReadiumTimebasedState.fromJson(json.decode(event) as Map<String, dynamic>);

    state.currentLocator?.locations?.let((locations) {
      if (locations.position == null) {
        debugPrint('Received timebased player state with currentLocator missing position: $state');
      } else if (locations.position! <= 0) {
        debugPrint('Received timebased player state with currentLocator invalid position: $state');
      }
    });

    return state;
  }).asBroadcastStream();
