Can't register media keys on macOS with system scope

[aluedtke7]

When I register a media key like PhysicalKeyboardKey.mediaPlayPause with system scope, I get the error:

Could not cast value of type 'NSNull' (0x14e87f280) to 'NSNumber' (0x1f459cdd8).

and the app terminates. I can register such keys with the scope inapp without a crash, but then I don't get any events in the keyDownHandler or keyUpHandler. On the other side, I'm able to register i.e. a hotkey for F9 with system scope that does work as expected.

When I use LogicalKeyboardKey.mediaPlayPause instead, the behavior and error message is the same (only the value of NSNull is slightly different).

Please let me know if further details are needed.

HotKey playPauseHK = HotKey(key: PhysicalKeyboardKey.mediaPlayPause, modifiers: [], scope: HotKeyScope.system);

await hotKeyManager.register(
  playPauseHK,
  keyDownHandler: (key) {
    debugPrint('PlayPause down: ${key.toJson()}');
  },
  keyUpHandler: (key) {
    debugPrint('PlayPause up: ${key.toJson()}');
  },
);

I think it's not a good idea to register media keys XD
If you wanna use media keys to control media play, I think using audio_service is a better way

Thank you for pointing me to that package. I'll have a look.

@aluedtke7 By the way, It does NOT support Windows. If you wanna use it on Windows, use smtc_windows instead
