Getting error when using multiprovider and consumer in flutter - firebase

Question

I recently updated firebase dependencies. I do not recommend this, by the way, I am having an awful experience. Google can't figure out what naming conventions to go by.
after updating and fixing all of the errors they caused I tried to run my app and got the initialize firebase error. Well after that error was mitigated I seem to have run into an error I cannot solve.
Here is the relevant code.
Widget build(BuildContext context) {
return StreamProvider<UserTutor>.value(
value: AuthService().user,
child: Consumer<UserTutor>(
builder: (_, user, __) {
return MultiProvider(
providers: [
user == null
? StreamProvider<Tutor>.value(
value: DatabaseService().streamTutor,
)
: StreamProvider<Tutor>.value(
value: DatabaseService(uid: user.uid).streamTutor,
),
user == null
? StreamProvider<List<ClassData>>.value(
value: DatabaseService().classdata)
: StreamProvider<List<ClassData>>.value(
value: DatabaseService(uid: user.uid).classdata),
],
child: MaterialApp(
home: Wrapper(),
debugShowCheckedModeBanner: false,
),
);
},
));
}
final FirebaseAuth _auth = FirebaseAuth.instance;
final GoogleSignIn googleSignIn = GoogleSignIn();
//create user obj based on firebase user
UserTutor _userFromFirebaseUser(User user) {
return user != null ? UserTutor(uid: user.uid, email: user.email) : null;
}
//auth change user stream
Stream<UserTutor> get user {
return _auth
.authStateChanges()
.map((User user) => _userFromFirebaseUser(user));
}
and here is the error I am receiving.
