additionalUserInfo not exposed on Android

[braincomb]

Hi @robingenz ,

I see that this feature has been added as part of the #30 , however in my testing I'm currently unable to see additionalUserInfo being exposed on an Android device. I can see it though when testing on a web browser.

It seems I'm only getting the credential from the SignInResult and nothing else. Using Google sign-in.

Any ideas?

Config:

    "FirebaseAuthentication": {
      "skipNativeAuth": true,
      "providers": ["apple.com", "google.com", "facebook.com"]
    }

Using:
"@capacitor-firebase/authentication": "^1.2.0"
Android 9 / Chrome Mobile WebView 107

Update: I found that setting skipNativeAuth to false fixes the issue and I can see additionalUserInfo being returned. This is an issue for me however, since I'm using Firebase JS SDK and have an Apple Sign-In provider so skipNativeAuth=true is required.

You can set skipNativeAuth to true for Apple only:

const appleResult = await FirebaseAuthentication.signInWithApple({ skipNativeAuth: true });
...
const googleResult = await FirebaseAuthentication.signInWithGoogle({ skipNativeAuth: false });

This way you should get additionalUserInfo for both providers because Apple returns this information with and without skipNativeAuth.

Hi @robingenz ,

Thanks for the response, using Google sign-in with FirebaseAuthentication.signInWithGoogle({ skipNativeAuth: false }); worked great on Android.

However, I just tested Apple sign-in on iOS device, and FirebaseAuthentication.signInWithApple({ skipNativeAuth: true }); does NOT return additionalUserInfo. Only changing it to skipNativeAuth: false makes it return the data, but since I'm using JS SDK that is not an option for me.

On iOS, unfortunately, the plugin only has access to this data after authentication. I will improve the documentation regarding this. What data do you need exactly?

[braincomb]

I'm only looking for additionalUserInfo.isNewUser, if that is only available after the authentication, then I'm assuming isNewUser will always return false?

I'll probably just end up implementing my own way of checking new user, due to the inconsistent way this is returned.

Thanks again.
