Google sign in APP CRASH on IOS

Troubleshooting

My iOS app crashes immediately after pressing the Google Sign-In button

Hi everyone, I’m running into an issue on iOS with Google Sign-In. As soon as I tap the Google Sign-In button, the app instantly crashes and closes before any Google popup appears.
I never get the Google account selection screen the app just quits.

This only happens on iOS devices (TestFlight / real device).

If anyone has seen this before or knows what could cause this crash (URL Schemes? reversed client ID? Info.plist?), I’d really appreciate help.

What have you tried so far?

Verified that no extra spaces or wrong characters were in the plist file.

Checked that “Sign in with Google” is enabled in Firebase → Authentication.

Did you check FlutterFlow's Documentation for this topic?
