@bizz84
i am enjoing your tutorial
but i want to use email verification , if user register with email

```
@override
Future signInWithEmailAndPassword(String email, String password) async {
final authResult = await _firebaseAuth.signInWithEmailAndPassword(
email: email, password: password);
print('aaa');
if (authResult.user.isEmailVerified) {
return _userFromFirebase(authResult.user);
} else {
return _userFromFirebase(null);
}
}

@override
Future createUserWithEmailAndPassword(
String email, String password) async {
final authResult = await _firebaseAuth.createUserWithEmailAndPassword(
email: email, password: password);
await authResult.user.sendEmailVerification();

return _userFromFirebase(authResult.user);
}
```

but, with that code, although isEmailVerified = is false
and return return _userFromFirebase(null);
but still go to home page
