Creating a Firebase user does not update authStateChanges method - flutter

Question

Quick question. Whenever I create a firebase user with email and password, the routing does not take the user to his correct page.
User user = context.watch<User>();
if (user == null) return LoginScreen();
///
rest of the code here where the user type stored in Firestore decides which page to navigate to
///
The createUserWithEmailAndPassword documentation does not say that it updates the authStateChanges method.
On the other hand, signInWithEmailAndPassword and FirebaseAuth.instance.signOut() documentations clearly states that it updates the authStateChanges method. And when I login the user is indeed taken to the correct page.
I assumed that createUserWithEmailAndPassword would do the same.
So should I navigate the user to the correct page manually (while popping all previous routes)?
Thank you in advance.
Routing Code:
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
// final _themeProvider = Provider.of<ThemeProvider>(context);
return MultiProvider(
providers: [
ChangeNotifierProvider<ThemeProvider>(create: (context) => ThemeProvider()),
Provider<CurrentUser>(create: (context) => CurrentUser()),
StreamProvider(create: (context) => context.read<CurrentUser>().authStateChanges),
],
child: MaterialApp(
home: LandingRouting(),
),
);
}
}
class LandingRouting extends StatelessWidget {
const LandingRouting({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
logger.w('Landing Routing ...');
User user = context.watch<User>();
if (user == null) return LoginScreen();
return FutureBuilder(
future: FirebaseFirestore.instance.collection('users').doc(user.uid).get(),
builder: (context, AsyncSnapshot<DocumentSnapshot> snapshot) {
if (snapshot.connectionState == ConnectionState.waiting) return Loading();
if (snapshot.hasError)
return AlertDialog(
title: Text('Error loading user'),
content: Text('${snapshot.error.toString}'),
);
else {
Map<String, dynamic> userData = snapshot.data.data();
assert(userData['userType'] != null, 'User Type cannot be null');
if (userData['userType'] == 'baqala') {
return BaqalaUserScreen();
} else {
return UserHomeScreen();
}
}
},
);
}
}
Sign up code:
class BaqalaAuth {
static void registerBaqala({
#required BuildContext context,
#required String baqalaName,
#required String license,
#required String landlineNumber,
#required String mobileNumber,
#required String email,
#required String password,
#required double lat,
#required double long,
}) async {
try {
FirebaseAuth.instance.createUserWithEmailAndPassword(email: email, password: password).then(
(userCred) async {
BaqalaInit.initBaqala(
context: context,
user: userCred.user,
landlineNumber: landlineNumber,
mobileNumber: mobileNumber,
licenseNumber: license,
baqalaName: baqalaName,
lat: lat,
long: long,
);
await userCred.user.updateProfile(displayName: baqalaName);
},
);

Login Code
class Auth {
static void login({
#required BuildContext context,
#required String email,
#required String password,
}) async {
try {
FocusScope.of(context).unfocus();
await FirebaseAuth.instance.signInWithEmailAndPassword(email: email, password: password);
} on PlatformException catch (e) {
logger.i('Login: Firebase Auth Exception');
_loginException(context, 'Error: ${e.code}\n\n${e.message}');
} on FirebaseAuthException catch (e) {
logger.i('Login: Firebase Auth Exception');
_loginException(context, 'Error: ${e.code}\n\n${e.message}');
} catch (e) {
_loginException(context, 'Login: Error: ${e.toString}');
}
}
static Future<void> logout() async {
await FirebaseAuth.instance.signOut();
}
}
