IOS: TimebasedState.ended not triggered when player reached end of publication

[emmiemmy]

It appears the following stream is not triggered when the player has reached the end of the publication. It works on Android just fine.

in flutter_readium.dart

  Stream<ReadiumTimebasedState> get onTimebasedPlayerStateChanged {
    return _platform.onTimebasedPlayerStateChanged;
  }

Expected result:
The stream should be triggered with TimebasedState.ended when player had resched the end of the publication.
