Answer 1

use ScreenUtilInit like this

@override
  Widget build(BuildContext context) {
    // In first method you only need to wrap [MaterialApp] with [ScreenUtilInit] and that's it
    return ScreenUtilInit(
      builder: (_, child) {
        return MaterialApp(
          debugShowCheckedModeBanner: false,
          title: 'Test',
          theme: ThemeData(
            primarySwatch: Colors.blue,
            textTheme: TextTheme(bodyText2: TextStyle(fontSize: 30.sp)),
          ),
          home: child,
        );
      },
      child: HomePage(),
    );
  }
}
