[iOS] Not able to override `.click` method

[838]

Documented behaviour

| Feature | Android | iOS | macOS | Web | | headset clicks | ✅ | ✅ | ✅ | ✅ |

Actual behaviour

The .click method does not get called on iOS.

On android when using headset buttons there will be 'I/flutter (24649): ----- LOG: click(MediaButton.media)` but on iOS no logs will be outputted.

Or if in iOS trying to override the .click method either in AudioPlayerHandler or MainSwitchHandler, it won't have any effect.

  @override
  Future<void> click([MediaButton button = MediaButton.media]) {
    debugPrint('Do something...');

    return super.click(button);
  }

Minimal reproduction project

Official example: example_multiple_handlers.dart

Reproduction steps

1. Run example_multiple_handlers.dart on an iOS device
2. Connect your headset
3. Start audio playback
4. Use play/pause button on headset

Do you have any idea what could be the cause of this issue or guild me how I could debug it?

@ryanheise I'm not sure this is the right way to do, but I could get click event by:

Creating a new clickNext method

- (MPRemoteCommandHandlerStatus) clickNext: (MPRemoteCommandEvent *) event {
    //NSLog(@"togglePlayPause");
    [handlerChannel invokeMethod:@"click" arguments:@{
        @"button":@(1)
    }];
    return MPRemoteCommandHandlerStatusSuccess;
}

and call it from

        case ASkipToNext:
            if (enable) {
                [commandCenter.nextTrackCommand addTarget:self action:@selector(clickNext:)];
            } else {
                [commandCenter.nextTrackCommand removeTarget:nil];
            }
            break;

Do you have any recommendation?
