import 'package:smart_sizer/smart_sizer.dart';

void main() {
  runApp(
      return const MyApp(),
  );
}

or

class MyHomePage extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return   SizeBuilder(
          baseSize: Size(360, 690),
          height: context.screenHeight,
          width: context.screenWidth,
          child: MaterialApp(
      
            debugShowCheckedModeBanner: false,
            home : MainScreen(),
          ));
  }

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Container(
          width: context.getWidth(60),
          height: context.getHeight(20),
          color: Colors.blue,
          child: Text(
            'Hello Ahmed',
            style: TextStyle(fontSize: context.getFontSize(16)),
