FirebaseAuth phone authentication error, error code 17499

Question

I started getting below error with Firebase Phone Authentication in my flutter app. What does error code 17499 mean? I couldn't get any info on this. Any hints to fix this? Thanks

E/FirebaseAuth(20851): [SmsRetrieverHelper] SMS verification code request failed: unknown status code: 17499 Requests from this Android client application xx.xxxxx.xxxxxxx are blocked.

    verificationCompleted: (AuthCredential auth) async {
      await _auth.signInWithCredential(auth).then((UserCredential value) {
        if (value != null && value.user != null) {
          print('Authentication successful');
          onAuthenticationSuccessful(context, value);
        } else {

Did you see https://stackoverflow.com/questions/51925442/firebase-auth-requests-from-this-android-client-application-com-xxx-are-blocked, and others from [searching for the error message](https://www.google.com/search?q=17499+Requests+from+this+Android+client+application+xx.xxxxx.xxxxxxx+are+blocked)? — Frank van Puffelen, Feb 22 '22 at 14:50
@FrankvanPuffelen I have tried most of the solutions mentioned in these links, nothing is working for me. — Krishna Shetty, Feb 22 '22 at 15:43
Is there clear solution? I have added SHA1 and SHA256, downloaded the google-services.json and used it in my project. Phone auth is enabled on Firebase console. What else do I need to do? — Krishna Shetty, Feb 22 '22 at 15:50

This worked from after migrating to Dart only FlutterFire initialisation method. It stopped working with manual initialisation using google-services.json.
