The best way is using a state manager. My main.dart Works with get, like this :

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

  @override
  Widget build(BuildContext context){
    
    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);


    try {
      return GetX<AppController>(
        builder: (ac) => (
          _buildWithTheme(context, ac)
        )
      );
    } catch(_){}

  }

Widget _buildWithTheme(BuildContext context, AppController state) {

    return  MaterialApp(
      title: 'APP',
      theme:  makeAppTheme(),      
      darkTheme: makeAppTheme(),     
      debugShowCheckedModeBanner: false,
      initialRoute: '/',
      locale: setLocale(state),
    );
  }

setState can be used when changing the value:

int i = 0;

setState(() {
  i = 1;
});

print(i);

Result:
