Current Behavior

Google Sign-In on iOS crashes immediately when tapping the button. No Google account picker appears.
Incompatible dependency versions automatically managed by FlutterFlow:
google_sign_in: 6.3.0
google_sign_in_ios: 5.9.0 ← incompatible with google_sign_in 6.x (requires 6.x)

Expected Behavior

google_sign_in_ios should be version 6.x to match google_sign_in 6.3.0.
Google Sign-In on iOS should open the account picker without crashing.

Steps to Reproduce

1. Create a FlutterFlow project with Supabase Authentication
2. Enable Google Authentication in App Settings → Authentication
3. Add a button with Auth Log In → Google action
4. Deploy to iOS device via TestFlight
5. Tap the Google Sign-In button
6. App crashes immediately - no account picker appears
