I am doing the registration with firebase and I got an issue the signUp button . I created a file Firebase_auth_services.dart that has this code

class FirebaseAuthServices {
  FirebaseAuth _auth = FirebaseAuth.instance;

  Future<User?> signUpWithEmailAndPassword(
      String email, String password) async {
    try {
      UserCredential credential = await _auth.createUserWithEmailAndPassword(
          email: email, password: password);
      return credential.user;
    } catch (e) {
      print('Some error occured');
    }
    return null;
  }

  Future<User?> signInWithEmailAndPassword(
      String email, String password) async {
    try {
      UserCredential credential = await _auth.signInWithEmailAndPassword(
          email: email, password: password);
      return credential.user;
    } catch (e) {
      print('Some error occured');
    }
    return null;
  }
}

and I created this method in my signup page :

class LoginScreen extends StatefulWidget {
  const LoginScreen({super.key});
  @override
  _LoginPageState createState() => _LoginPageState();
}

var elements1 = [
  'Customer',
  'Business',
];
String dropdownvalue = 'Customer';
TextEditingController _usernameController = TextEditingController();
TextEditingController _emailController = TextEditingController();
TextEditingController _passwordController = TextEditingController();
bool isSigningUp = false;
final FirebaseAuthServices _auth = FirebaseAuthServices();

class _LoginPageState extends State<LoginScreen> {
  @override
  void dispose() {
    _usernameController.dispose();
    _emailController.dispose();
    _passwordController.dispose();
    super.dispose();
  }

  final _formKey = GlobalKey<FormState>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.white,
      body: Padding(
          padding: const EdgeInsets.only(top: 50.0, left: 30, right: 30),
          child: Column(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: [
              Logo(),
              SignUpButton(),
              SizedBox(
                height: 30,
              ),
              Container(
                height: 62,
                width: 350,
                child: ElevatedButton(
                  style: ElevatedButton.styleFrom(
                      backgroundColor: Colors.black,
                      shape: RoundedRectangleBorder(
                        borderRadius: BorderRadius.circular(32),
                      )),
                  onPressed: _signUp,
                  child: Text(
                    'Sign Up',
                    style: TextStyle(color: Colors.white),
                  ),
                ),
              ),
              SizedBox(
                height: 10,
              ),
              LoginButton(),
            ],
          )),
    );
  }

  void _signUp() async {
    String username = _usernameController.text;
    String email = _emailController.text;
    String password = _passwordController.text;

    User? user = await _auth.signUpWithEmailAndPassword(email, password);

    if (user != null) {
      print("User is successfully created");
      Navigator.pushNamed(
          context, "/Users/lilianasanda/influfit/lib/Homepage.dart");
    } else {
      print("Some error happend");
    }
  }
}

and this is the error I received :

I also changed that path in _signUp method with Navigator.pushNamed(
context, “/home”) but I am receiving the same error
