main.dart is not found in project when archiving flutter app

Question

I'm trying to archive my flutter app in distributing it to testers first. I have made and added schemas in Xcode for different flavours of the app. I also use amplify_core plugin. First when I try to clean build it gave me an error saying

"Compiling for iOS 11.0, but module 'amplify_core' has a minimum deployment target of iOS 16.0:"

After a little bit of researching I've made the apmlify_core min deployment target to 11 under runner in Xcode pods. Then the build was successful. but when I try to do an archive it gives me this error

"package:/main.dart: Error: No 'main' method found. Try adding a method named 'main' to your program."

I will paste my main.dart and one flavour dart file for reference. anyone can help me with his. ?

main.dart file

class MyApp extends StatelessWidget {
  MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  final appRouter = AppRouter().router;

  @override
  Widget build(BuildContext context) {
    return MultiProvider(
      providers: [
        StreamProvider<EInternetStatus>(
          create: (context) =>
              ConnectionCheck().internetStatusController.stream,
          initialData: EInternetStatus.iLoading,
        ),
      ],
      child: MaterialApp.router(
        debugShowCheckedModeBanner: AppEnvironment.flavour == EFlavour.fDev ||
                AppEnvironment.flavour == EFlavour.fQa
            ? true
            : false,
        theme: FPTheme.lightTheme,
        routerConfig: appRouter,
      ),
    );
  }
}

main_dev.dart file

Future<void> main() async {
  AppEnvironment.setupEnv(EFlavour.fDev);
  WidgetsBinding widgetsBinding = WidgetsFlutterBinding.ensureInitialized();
  await AmplifyServices().configureAmplify();
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
  ]);
  SystemChrome.setEnabledSystemUIMode(SystemUiMode.leanBack);
  FlutterNativeSplash.preserve(widgetsBinding: widgetsBinding);
  setUp();
  runApp(MyApp());
}

im not sure what I do here wrong? if anyone can help me out with this it would be amazing

How are you running your app?
i think you haven't configured build using flavours correctly in your editor try using
flutter run -t lib/main_dev.dart

To configure your vs code to run with flavours try changing launch.json file.

 "configurations": [

{
  "name": "Flutter",
  "request": "launch",
  "type": "dart",
  "program": "${workspaceFolder}/lib/main_dev.dart"
}].
