Is your feature request related to a problem? Please describe.
I use GetMaterialApp.router in my project and use DevicePreview to test layout issues. However one thing is quite annoying that locale changes don't trigger the UI change.

Describe the solution you'd like
locale changes in device preview will trigger locale change in GetMaterialApp.router.

Apparently this worked for me:

// ...
  runApp(
    DevicePreview(
      availableLocales: const [
        Locale('en', 'US'),
        Locale('pt', 'BR'),
        // ...
      ],
      enabled: !kReleaseMode,
      builder: (context) => GetMaterialApp(
        builder: (BuildContext ctx, Widget? widget) {
          // ...
          DevicePreview.appBuilder(ctx, widget),
          // ...
        },
        translations: value_sets.AppLabels(),
        locale: () {
          if(!kReleaseMode) {
            Get.locale = DevicePreview.locale(context);
            return DevicePreview.locale(context);
          }
          return Get.deviceLocale;
        }(),
        fallbackLocale: const Locale('pt', 'BR'),
        // ...
      ),
    ),
  );
// ...
