ios – Drive ‘Join with ‘ circulation to reappear for Register with Apple in Flutter and retrieve electronic mail and fullName

The primary time I signed in with Apple in my app, I obtained the total Create an account for <app> utilizing your Apple ID circulation. Nevertheless, I used to be not in a position to see and save the e-mail and fullName fields.
In all subsequent logins after unique join, solely the uid is given by Apple. That is anticipated behaviour, see Can not get title & electronic mail with register with Apple on actual gadget

{
    credential =     {
        authorizationCode = "<FlutterStandardTypedData: 0x28195d5a0>";
        authorizedScopes =         (
        );
        electronic mail = "<null>";
        fullName =         {
            familyName = "<null>";
            givenName = "<null>";
            middleName = "<null>";
            namePrefix = "<null>";
            nameSuffix = "<null>";
            nickname = "<null>";
        };
        identityToken = "<FlutterStandardTypedData: 0x28195d460>";
        realUserStatus = 2;
        state = "<null>";
        person = "my person code";
    };
    credentialType = ASAuthorizationAppleIDCredential;
    standing = approved;
}

They advise to take away the app in my Register with Apple listing and that it ought to drive the unique display to point out up once more:

Sadly, for this account it doesn’t present the unique login circulation after this step, however simply the common Log in display, for if you find yourself a returning person.

Different steps I added:

• eradicating the report from the Authentication display within the Customers desk in Firebase.
• disabling, deleting and re-enabling the Apple Register in Firebase
• flutter clear
• flutter pub cache restore
• deleting the app from the take a look at gadget, rebooting take a look at gadget and rebuilding from Android Studio.
• eradicating and re-adding Register with Apple in XCode by way of Runner -> Signing & Capabilities
• logging in with my Google Register after which logging out so it clears my shared preferences:

SharedPreferences preferences = await SharedPreferences.getInstance();
await preferences.clear();
