Fix Google Sign-In Issues

If Google Sign-In isn’t working after exporting your FlutterFlow app, follow these steps based on how you’re deploying your app.

1. If Deployed to the Play Store via CodeMagic

   If you published your app to the Play Store using FlutterFlow's CodeMagic integration:

   • In the Google Play Console, open your app from the All apps list.
   • Go to Setup → App Integrity.
   • Under the App Signing tab, copy the SHA-1 certificate fingerprint.

   

   • In the Firebase console, open the same project, scroll to Your Apps, and select your Android app.
   • Click Add fingerprint, paste the SHA-1, then click Save.

   

   • In FlutterFlow, go to Settings → Firebase and click:
   • Regenerate Config Files
   • Generate Files

   

   Re-test your app. Google Sign-In should now work correctly.

2. If Not Yet Published or Using Manual Signing

   If you’re not using Play Store App Signing:

   • Use Keytool or Gradle's Signing Report to generate your SHA-1.
   • In Firebase, open your project settings.
   • Under Your Apps, select the Android app and add the SHA-1 fingerprint.

   

   • In FlutterFlow, go to Settings → Firebase, then:
   • Regenerate Config Files
   • Generate Files

   

   Test the app again to confirm Google Sign-In works.

   Refer to the Google Play Services documentation for more information.

Add Debug SHA-1 for Local Testing

• When testing Google Sign-In in FlutterFlow before publishing, add your debug SHA-1 in Firebase.
• Then go to Settings → Firebase in FlutterFlow and regenerate your config files.
