Google Sign-In failing with PlatformException(sign_in_failed, L0.d: 10, null, null) — tried everything...

Hi everyone,

My name is David.

I've been stuck on this for a long time and can't figure it out. My app is built with FlutterFlow + Supabase, and Google Sign-In keeps failing with this error:

`PlatformException(sign_in_failed, L0.d: 10, null, null)`

**What I've already checked/done:**

- SHA-1 fingerprint is registered in Google Cloud Console

- Package name is NOT com.example (already changed to a unique name)

- Web Client ID (not Android) is entered in Supabase

- Redirect URI (https://xxxx.supabase.co/auth/v1/callback) is registered in Google Cloud Console

- Google Provider is enabled in Supabase

- OAuth Consent Screen is set to External and I'm registered as a Test User

- Tested with a fresh APK install (removed old version first)

**My setup:**

- Built with FlutterFlow (via a third-party builder)

- Authentication: Supabase

- Testing on Android device via APK

Has anyone experienced this? What am I missing?

Thanks!
