apple_sign_in_firebase
Access Sign In with Apple in firebase
from flutter android.
Because you can't get the credential of an app with the flutter firebase alone, you can import the credential directly through the native firebase.
Getting Started
The project must have a pre-set firebase.
Platform support
Support only Android! There's a iOS framework.
Example
Map crendential = await AppleSignInFirebase.signIn();
print(credential['idToken']);
print(credential['accessToken']);
