未定义名称“AuthException”。 Firebase

Question

I am getting error like

Undefined name 'AuthException'

When I am trying to use it as following in my Flutter app.

  Future<bool> login({phoneNr, BuildContext context}) async {
    _auth.verifyPhoneNumber(
      phoneNumber: phoneNr,
      timeout: Duration(seconds: 60),
      verificationCompleted: (AuthCredential credential) async {
        UserCredential result = await _auth.signInWithCredential(credential);
        User user = result.user;
        if (user != null) {
          Navigator.pushNamed(context, HomeScreen.id, arguments: user);
        }
      },
    verificationFailed: (AuthException exception) // THIS LINE HERE
    );
  }

I know, they might have changed the name just like they did for "FirebaseUser" to just "User"; but their formal documentation still shows "AuthException" as a valid class. However despite importing and upgrading all expected packages, I am still getting the same error. Any solution?

Answer 1

Looking at the current api docs , you should use FirebaseAuthException instead.

You can as well remove the type and have it inferred: verificationFailed: (exception) {}

Answer 2

Use FirebaseAuthException instead of AuthException if you are using Flutter 2.
