I/flutter (14318): NoSuchMethodError: Class 'FirebaseUser' has no instance getter 'firstname'

I am trying to update the user profile of users of app I am building. The users information is stored in firebase, the app is coded in dart running on android.

I have tried implementing example from https://firebase.google.com/docs/auth/web/manage-users website.

 51   createUser() {
 52     if (checkFields()) {
 53       //Perform Login
 54       var user = FirebaseAuth.instance.currentUser();
 55       FirebaseAuth.instance
 56           .createUserWithEmailAndPassword(email: _email, password: _password)
 57           .then((user) {
 58             var  userUpdateInfo = new UserUpdateInfo();
 59             user.updateProfile(userUpdateInfo)
                    .then((user) {
 60                   userUpdateInfo.displayName = _Firstname;
 61                   FirebaseAuth.instance
                                  .currentUser()
                                  .then((user)  {
                                    UserManagement().storeNewuser(user, context);
 62                               })
                                  .catchError((e) {print(e);});
 63                 })
                    .catchError((e) {
 64                   print(e);
 65                 });
 66                 //UserManagement().storeNewuser(user, context);
 67                 Navigator.of(context).pop();
 68                 Navigator.of(context)
                             .pushReplacementNamed('/landingpage');
 69           })
              .catchError((e) {
 70             print("ivlvvliyviv");
 71           });
 72     }
 73   }

The app runs smoothly without does not crushing but when the user updates the firstname but it is not changed on firebase, line 60 was suppose to update the firstname field on firebase, and this is where I am adding my firstname field 

Firestore.instance
         .collection('/users')
         .add({ 
           'email': user.email, 
           'uid': user.uid, 
           'firstname': user.firstname,

In Order to Update Firebase User - displayName. You need to make few changes in your Code.

Make - var userUpdateInfo = new UserUpdateInfo(); state variable outside your .then Function. & then Call user.updateProfile.

or

Edit Your Create User code As Below:

FirebaseAuth.instance.createUserWithEmailAndPassword(email: _email, password: _password)
      .then((user) {
    var  userUpdateInfo = new UserUpdateInfo();
    userUpdateInfo.displayName = _Firstname;  // Pass the value you want as displayName
    user.updateProfile(userUpdateInfo).then((val){  // will Update the User at Firebase Auth
      print('User Display Name Updated.');
    });
  });
