null authorizationCode when signing in with apple on Android

[pamafe1976]

Hi

I'm using this flutter code to retrieve credential for sign in with apple:

      final appleProvider = AppleAuthProvider()
        ..addScope('email')
        ..addScope('name');

      UserCredential credential = await FirebaseAuth.instance.signInWithProvider(appleProvider);

In IOS it returns a valid authorizationCode. However in Android the authorizationCode is always null.
I need the authorizationCode to be able to revokeTokenWithAuthorizationCode when the user deletes the account.
What am I doing wrong?

Regards
