AppTrackingTransparency permission dialog doesn't show up

I'm asking for tracking-transparency permission using the permission_handler in my app:

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  Map<Permission, PermissionStatus> statuses = await [
    Permission.photosAddOnly,
    Permission.camera,
    Permission.microphone,
    Permission.appTrackingTransparency,
  ].request();
  runApp(const MyApp());
}

All permission dialogs appear except for the appTrackingTransparency one.

Why it doesn't show up?

flutter doctor

You must list permission you want to use in your application

Inside your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
      '$(inherited)',
      'PERMISSION_APP_TRACKING_TRANSPARENCY=1',
      ]
    end 
  end
end

I decided to use the app_tracking_transparency. But the dialog still doesn't show up.

After reading about swift solutions, according to this post, adding a minor delay between dialogs seems to solve it.

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await [
    Permission.photosAddOnly,
    Permission.camera,
    Permission.microphone,
  ].request();

  /// Getting permission for appTrackingTransparency required a delay between prompts.
  if (await AppTrackingTransparency.trackingAuthorizationStatus ==
      TrackingStatus.notDetermined) {
    await Future.delayed(const Duration(seconds: 2));
    await AppTrackingTransparency.requestTrackingAuthorization();
  }

  runApp(const MyApp());
}

Note: I don't know why, but it worked only with the app_tracking_transparency package, but not with the permission_handler package.

Still Looking for a better solution, using the permission_handler package, that does not delay the app load time.
