Issue with Google Sign-In on Android (Firebase Auth)

Hi,

I'm using Firebase Authentication with Google Sign-In in my FlutterFlow app. It works perfectly on iOS, but on Android, I’m facing an issue:

• The Google Sign-In popup appears.

• I select my email.

• The popup closes immediately without logging in.

I have already:
✅ Added both SHA-1 and SHA-256 keys in my Firebase settings.
✅ Regenerated the necessary files in FlutterFlow.
✅ Tried multiple times, but the issue persists—Google login remains impossible on Android.

Has anyone encountered this issue or knows how to fix it?

Thanks in advance!
