Robotframework: Unable to redirect after createUserWithEmailAndPassword() - Flutter project using Firebase Authentication

[IhssaneTAJ]

I have a form to create a firebase user using createUserWithEmailAndPassword() and a button who redirect to home page. after I click on the button, the user account is created successfully but without redirection to another page

the button's code in 'register.dart'

child: FlatButton(
                    onPressed: () {
                      FirebaseAuth.instance.createUserWithEmailAndPassword(
                          email: _emailController.text,
                          password: _passwordController.text
                      ).then((signedUser){
                        UserToDatabase().addNewUser(signedUser, context);


         ****                 Navigator.of(context).pushReplacementNamed('/home');




                      }).catchError((e){
                        print(e);
                      });
                    },
                    child: Center(
                      child: Text("S'inscrire"),
                    ),
                  ),

user_to_database.dart

import 'package:car_app/GUI/bottomNavBar.dart';
import 'package:firebase_database/firebase_database.dart';
import 'package:flutter/material.dart';
import 'package:flutter/widgets.dart';

class UserToDatabase{
  addNewUser(user, context){
    FirebaseDatabase.instance.reference().child('users').push().set({
      'email' : user.email,
      'uid' : user.uid
    }).then((value){

        Navigator.push(context, new MaterialPageRoute(builder: (context) => new BottomNavBar()));

    }).catchError((e){
      print(e);
    });
  }
}

I want to know what should I change so that I can redirect to home page. this is what I get as error messages:

@IhssaneTAJ This does not look related to robotframework. Wrong issue tracker?

[malkny]

UserToDatabase().addNewUser(signedUser.user, context); //try to add 'user' on this line

[ahmadrayan]

If you find the solution, please let me know

[Ibrahim-Unbreakable]

UserToDatabase().addNewUser(signedUser.user, context); //try to add 'user' on this line

Thank you this worked for me
