Apple OAuth problem for Android-Flutter

[abdurrahimyilmaz]

I am developing a flutter app. I have succesfully implemented native and web signins for Google/Apple and Google sign in for Apple. However, Apple Sign in for Android does not return back to my app. if I want to use app return deeplinking (e.g. com.example.mobileAppTemplate://login-callback), nothing happen first time when I click to continue button. Second time Apple give an error and cant return back to app. If I want to use URL based deeplinking (e.g. http://localhost/foo), Apple redirect to the URL but I cant return back to app. I have also tried manual deeplinking using app_links library, but still I cant go back.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Apple SignIn
2. Succesful SignIn in WebView
3. Continue Sign In using my Apple ID
4. Nothing Happen
5. Click Again
6. Receive error

Expected behavior

After succesful login, I can return back to app.
