ROLE BASED AUTHORIZATION AND ROLE BASED ACCESS CONTROLL !! flutter/firebase

[Error Place]

Hey guys!

what im trying to do is to setup a role based authorization (reqular users and subscribed users) and based on roles users gets redirected to different screens. i am STUCK. ive tried different solutions and seen every tutorial there is out there about the concept. i understand how the concept works but having a realy hard time setting it up in my code. im not sure where to declare the subscribed users and how create the function and how to Navigate them! 

greatful for any help! this is how my code looks!

//this is my auth services

 static void signUpUser(
  BuildContext context, String name, String email, String password) async {
try {
  AuthResult authResult = await _auth.createUserWithEmailAndPassword(
      email: email,
      password: password
  );
  FirebaseUser signedInUser = authResult.user;
  if (signedInUser != null) {
    _firestore.collection('/users').document(signedInUser.uid).setData({
      'name': name,
      'email': email,
      'profileImageUrl': '',
    });

//sign up page

 final _formKey = GlobalKey<FormState>();
  String _name, _email, _password;

  _submit() {
    if(_formKey.currentState.validate()){
      _formKey.currentState.save();

      AuthService.signUpUser(context, _name, _email, _password);
    }
  }

//my main.dart
 Widget _getScreenId() {
    return StreamBuilder<FirebaseUser>(
      stream: FirebaseAuth.instance.onAuthStateChanged,
      builder: (BuildContext context, snapshot) {
        if (!snapshot.hasData) {
          Provider.of<UserData>(context).currentUserId = snapshot.data.uid;
          return LoginScreen();
        } else {
          return HomeScreen();
        }
      },
    );
  }

save isAdmin in the document. In the same way you do in Biografy.

Ive nog created the Update function, so my users can update their information 

     Class DatabaseService {

      static void updateUserData(User user){

      UsersRef.document(user.id).updateData({

      Name .......

      Profile image ........

       Biografy.......

});

}

But I still don’t know how to set the isAdmin = true;

I want the user to be able to choose admin! Or regular user in the signup page and then based on the chosen role get directed to different screens!

Thanks in advance 🙏

Good. Then you need to know how to save a document per user. Very similar to 

_firestore.collection('/users').document(signedInUser.uid).setData({
      'name': name,
      'email': email,
      'profileImageUrl': '',
    })

But with “updateData” method this time. For difference between setData and updateData:

Thank you for your response.

My app runs on both iOS and Android, and it also signs up user. But it doesn’t assign roles to user  though I don’t know how to write the code that makes it happen! I can set user roles manually in the firebase console but don’t know how to figure out the navigation either.

Best regards

Does your app run in yours device (iOS/Android/Web)?

Does your app let your user sign-in?

Does your app assign a role to a user?

Does your users see different pages by the role?

What I’m would like to achieve is that users with admin role get special UI and access to every page

While regular user only can  see some pages.

You will need to learn about custom claims.
