hmm, I've copied\pasted your code, everything looks normal. Can you please provide me with flutter doctor -v results and the full code of your screen?

The appearance of my project is right to left I checked for right-to-left apps.

If you add the following code to the main.dart file, and use flutter_localizations package, you can check better

  localizationsDelegates: [

// AppLocalizations.delegate, GlobalMaterialLocalizations.delegate, GlobalWidgetsLocalizations.delegate, GlobalCupertinoLocalizations.delegate, ], supportedLocales: [ // const Locale('en', ''), const Locale('fa', ''), ],
