Question 119847 in Firebase Question posted in
An extensive official documentation can be found here.

Firebase – PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 12500: , null, null)

I know this question have been asked and answered multiple times. But my case is a bit different.

My flutter app is available on both Google Play and App store. The Google Sign In worked perfectly. But it suddenly makes the error below while I am updating it. This error occurs in both debug and release mode. I didn’t make any major pubspect(pod) change. I checked SHA,OAuth Screen, supporting email, which were checked before publishing the app. This version hasn’t been published yet. The current version on Google Play and App Store works fine with Google SignIn. Any help??

    I figured this out by adding SHA1 to Firebase and replacing google-services.json file.
