StreamBuilder snapshot is inactive on creating own stream - flutter

Question

It is a firebase authentication system with email verification. I am using 2 streams, one is firebase authstatechanges and one of my own to check mail verification status.
I am using a stream combiner for combining 2 streams.
On combining 2 streams and calling the function in stream builder, the snapshot was returning an inactive state. It was not even entering the method "combinestream". Then I tried checking my own stream and passed it to streambuilder alone this time. I found out that it was giving the same problem.
Here is my stream controller code with 2 streams combined:
class AuthService {
final userVerificationStreamController = StreamController<bool>.broadcast();
final auth.FirebaseAuth _firebaseAuth = auth.FirebaseAuth.instance;
MyUser? _userFromFirebase(auth.User? newUser) {
if (newUser == null) {
return null;
}
print("^^^^^------?>>>>>>>>> ${newUser.uid} ,, ${newUser.email} ,, ${newUser.emailVerified}");
return MyUser(newUser.uid, newUser.email,newUser.emailVerified);
}
Stream<CombineStreamer> get combineStream {
Stream<MyUser?> firebaseAuthStream = _firebaseAuth.authStateChanges().map(_userFromFirebase);
Stream<bool> userVerificationStream = userVerificationStreamController.stream;
print("######___>>>>>>>>>> COMBINING STREAMS");
return firebaseAuthStream.combineLatest(userVerificationStream, (p0, p1){
if(p0==null){
userVerificationStreamController.sink.add(false);
}
else if(p0.isEmailVerified){
userVerificationStreamController.sink.add(true);
}
if (p1.toString().toLowerCase() == 'true') {
print("______+++++++___****** ${p1.toString().toLowerCase()}");
return CombineStreamer(p0,true);
} else{
print("______+++++++___>>>>>> ${p1.toString().toLowerCase()}");
return CombineStreamer(p0,false);
}
}
.....
....
}
I called this combineStream method in wrapper class like:
Widget build(BuildContext context) {
final authService = Provider.of<AuthService>(context, listen: false);
return StreamBuilder(
stream: authService.combineStream,
builder: (BuildContext context, AsyncSnapshot snapshot){
if(snapshot.connectionState == ConnectionState.active){
print("!!!!___--->>>>> THE STATE IS ACTIVE");
CombineStreamer? streamedData = snapshot.data;
if(streamedData!=null) {
if(streamedData.user == null || !streamedData.isUserVerified){
print("!!!!___--->>>>> GOING TO LOGIN PAGE");
return LoginPage();
}
else{
print("!!!!___--->>>>> GOING TO HOMEPAGE");
return HomePage();
}
}
else{
print("!!!!!!###### SNAPSHOT IS NULL");
return const Scaffold(body: CircularProgressIndicator(color: Colors.red,),);
}
}
else{
print("!!!!___--->>>>> SHOWING CIRCULAR INDICATOR");
return const Scaffold(body: Center(child: CircularProgressIndicator(),));
}
},
);
}
Here it ALWAYS shows me the circular progress indicator of blue color the default one, where the snapshot is inactive. I am not able to figure out what's causing this problem. Please look into this.
And add the comment if you think something is missing. Thanks!
