Can't catch exception Firebase Realtime database

I am trying to throw a message when the password is less than 6 characters, but I can’t catch the exception.

                  final email = _email.text;
                  final password = _password.text;
                  try {
                    final userCredential = await FirebaseAuth.instance
                        .createUserWithEmailAndPassword(
                        email: email,
                        password: password
                    );
                    
                    print(userCredential);
                  } on FirebaseAuthException catch (e) {
                      print(e.runtimeType);
                      print ('Password should be at least 6 characters long');
                      print(e);
                  }

I am trying to do it like this but the terminal keeps showing me that the Exception is Unhandled:

W/System  (18810): Ignoring header X-Firebase-Locale because its value was null.

I am using a realtime database with flutter.

What am I doing wrong?

>Solution :

Try :

 on FirebaseAuthException catch (e) {
    print(e.code);
    print(e.message);
 }
