每当我在vs代码和热重新加载中更改代码时，我的Flutter web应用程序都会注销

Question

我在Flutter Web应用程序上使用Firebase身份验证，但在热重启或chrome刷新后，会话不会持久化。

在安卓系统中，它可以正常工作，但在热重新加载或chrome刷新用户注销后，在网络应用程序中可以正常工作。

在谷歌上搜索了大约12个多小时后，我仍然没有找到解决方案。

也遵循这个答案@frankvanpuffelen的解决方案，但仍然面临同样的问题。

这张罚单仍未解决。

如果可能，请运行以下代码。

我期待着你的回答。

这是我在main.dart 中的代码

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const AuthGate());
}
class AuthGate extends StatelessWidget {
  const AuthGate({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: StreamBuilder<User?>(
        stream: FirebaseAuth.instance.authStateChanges(),
        builder: (BuildContext context, AsyncSnapshot<User?> snapshot) {
          if (!snapshot.hasData) {
            return const FlutterFireUiLogin();
          } else {
            return const Text("You are Logged In");
          }
        },
      ),
    );
  }
}

这是我的flutterfire_ui_login.dart

import 'package:flutter/material.dart';
import 'package:flutterfire_ui/auth.dart';
class FlutterFireUiLogin extends StatelessWidget {
  const FlutterFireUiLogin({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Container(
        padding: const EdgeInsets.all(20),
        child: SignInScreen(
          providerConfigs: const [
            EmailProviderConfiguration(),
            PhoneProviderConfiguration(),
          ],
        ),
      ),
    );
  }
}

这是我的pubspec.yaml
