[Flutter] 7943 7943 I flutter : Login failed: PlatformException(sign_in_failed,...

After publishing my app to google playstore, the above error appears in the adb logcat during the google login of the app, but the google login of the released apk works without any problem. (None of the authentication functions work in playstore published app)

I have the google play console "app signing key certificate" sha1 fingerprint pasted correctly in firebase.
