Flutter：每当我按下主页按钮时，我都会重定向到登录屏幕

Question

我做了一个简单的应用程序，我正在使用 firebase 身份验证我在这个应用程序中使用了侧抽屉 该应用程序在所有其他选项卡上都可以正常工作，但是当我从侧抽屉按下主页按钮而不是转到主屏幕时（初始页面路径）登录页面来了出，如果在同一时间我热重新加载应用程序，那么我会自动重定向到主屏幕

2 天前，该应用程序目前运行良好，但今天正在发生这种情况。

这是我的 Main.dart 文件：

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();

  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  static const myApproute = 'myapproue';
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final screen = [
    const HomePage(),
    AnnoucementScreen(),
    const AdminScreen(),
    const SettingsScreen(),
  ];

  int currentIndex = 0;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(
        pageTransitionsTheme: PageTransitionsTheme(
          builders: {
            TargetPlatform.android: CustomPageTransitionBuilder(),
          },
        ),
      ),
      home: StreamBuilder(
          stream: Login().firebaseAuth.authStateChanges(),
          builder: (context, snapshot) {
            if (snapshot.hasData) {
              return Scaffold(
                body: screen[currentIndex],
                bottomNavigationBar: BottomNavigationBar(
                  type: BottomNavigationBarType.fixed,

                  // onTap: (value) => setState(() => currentIndex = value),
                  onTap: (value) {
                    setState(() {
                      currentIndex = value;
                    });
