Error :
This request is missing a valid app identifier, meaning that Play Integrity checks, and reCAPTCHA checks were unsuccessful. Please try again, or check the logcat for more details.

1 . enabled the Google Play Integrity Api (Android Device Verifiaction is depricated)
2 . added the debug, release and app signing key in firebase
3 . also try to debug it in test mode eg : FirebaseAuth.instance.setSettings(appVerificationDisabledForTesting: true);
