App小部件没有生成路由| firebase注册

Question

注册成功后，我试图将用户发送到主页(home)，解释如何使用该应用程序。我通过signup.dart上的此代码块这样做

onPressed: () async {
try {
User user =
(await FirebaseAuth.instance.createUserWithEmailAndPassword(
email: _emailController.text,
password: _passwordController.text,
))
.user;
if (user != null) {
user.updateProfile(displayName: _nameController.text);
Navigator.of(context).pushNamed(AppRoutes.home);
}
}

指向home路由

class AppRoutes {
AppRoutes._();
static const String authLogin = '/auth-login';
static const String authSignUp = '/auth-signup';
static const String home = '/home';
static Map<String, WidgetBuilder> define() {
return {
authLogin: (context) => Login(),
authSignUp: (context) => SignUp(),
home: (context) => Home(),
};
}
}

然而，当我注册时，数据在firebase中呈现，但用户没有被发送到home页面，并在我的控制台中抛出此错误

Make sure your root app widget has provided a way to generate
this route.
Generators for routes are searched for in the following order:
1. For the "/" route, the "home" property, if non-null, is used.
2. Otherwise, the "routes" table is used, if it has an entry for the route.
3. Otherwise, onGenerateRoute is called. It should return a non-null value for any valid route not handled by "home" and "routes".
4. Finally if all else fails onUnknownRoute is called.
Unfortunately, onUnknownRoute was not set.

有什么建议吗?

您是否在MaterialApp中添加了onGenerateRoute?这样的:

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
onGenerateRoute: Router.generateRoute,
initialRoute: yourRoute,
child: YouApp(),
);
}
}

class Router {
static Route<dynamic> generateRoute(RouteSettings settings) {
switch (settings.name) {
case AppRoutes.home:
return MaterialPageRoute(builder: (_) => Home());
case AppRoutes.authLogin:
return MaterialPageRoute(builder: (_) => Login());
case AppRoutes.authSignUp:
return MaterialPageRoute(builder: (_) => SignUp());
default:
return MaterialPageRoute(
builder: (_) => Scaffold(
body: Center(
child: Text('No route defined for ${settings.name}')),
));
}
}
}
}
}
