import 'package:go_router/go_router.dart';
import 'package:lestari/Pages/scanpage.dart';

import 'Pages/homepage.dart';
import 'Pages/loginpage.dart';

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

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

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    GoRouter router = GoRouter(
      routes: [
        GoRoute(
          path: "/",
          name: "home",
          builder: (context, state) => const HomePage(),
          routes: [
            GoRoute(
              path: "scan",
              name: "scan",
              builder: (context, state) => const ScanPage(),
            ) …
