    Here is a working code:

    import 'package:flutter/material.dart';
import 'package:hms/screens/login_screen.dart';

void main(List<String> args) {
  runApp(MyApp());
}
class MyApp extends StatelessWidget {
  MyApp({super.key}); //you forgot the ';' here and you should pass the key to super class
  // ignore: empty_constructor_bodies
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: LoginScreen(),
      );
  }
}

    You can fix it through this way:

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: LoginScreen(),
    );
  }
}
