Firebase Auth 甚至没有坚持应用重新加载，我已经浏览了许多 stackoverflow 的答案，但仍然无法弄清楚代码中有什么问题。以下是我的颤振代码，
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return SplashScreen();
}
}
class SplashScreen extends StatefulWidget {
static final route = '/';
@override
_SplashScreenState createState() => _SplashScreenState();
}
class _SplashScreenState extends State<SplashScreen> {
@override
Widget build(BuildContext context) {
return StreamBuilder<User>(
stream: FirebaseAuth.instance.authStateChanges(),
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.active) {
User user = snapshot.data;
return MaterialApp(home: (user == null) ? LoginPage() : HomePage());
} else {
return Container(
color: Colors.blueAccent,
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset(
'images/dove.png',
height: 150,
width: 150,
),
Padding(
padding: const EdgeInsets.fromLTRB(8.0, 32.0, 8.0, 60.0),
child: Text(
'Loading Pls Wait...',
style: TextStyle(
fontSize: 20,
color: Colors.black,
fontWeight: FontWeight.bold),
),
)
],
),
),
);
}
},
);
}
@override
void initState() {
super.initState();
}
}
每次我重新加载应用程序或运行应用程序时，它只会导航到登录屏幕，但是在登录屏幕中，当我使用电话号码登录时，它会导航到 MainPage 而不会在登录页面上编写任何代码，即authstate 更改在主屏幕中正确收听。以下是登录页面，
class LoginPage extends StatefulWidget {
static final route = '/Login_Page';
@override
_LoginPageState createState() => _LoginPageState();
}
class _LoginPageState extends State<LoginPage> {
@override
Widget build(BuildContext context) {
var media = MediaQuery.of(context).size;
final isSmall = ResponsiveWidget.isSmallScreen(context);
return Scaffold(
appBar: AppBar(
title: Center(child: Text('LogIn')),
),
body: Container(
color: Colors.blue,
child: Row(
children: [
(isSmall)
? Container()
: Padding(
padding: const EdgeInsets.all(100.0),
child: Container(),
),
Expanded(child: LogInInput())
],
),
),
);
}
}
class LogInInput extends StatefulWidget {
@override
_LogInInputState createState() => _LogInInputState();
}
class _LogInInputState extends State<LogInInput> {
final phnoController = TextEditingController(text: '+91');
final _formKey = GlobalKey<FormState>();
final _formKeyOTP = GlobalKey<FormState>();
var codeSent = false;
var onProcess = false;
final otpController = TextEditingController();
ConfirmationResult confirmationResult;
@override
Widget build(BuildContext context) {
final isSmall = ResponsiveWidget.isSmallScreen(context);
return Center(

我已在 Edge 和 Google Chrome 中检查过此行为，两者的行为相同。
有人可以帮忙吗？
