Google Sign-In crashes on iOS because FF_REVERSED_CLIENT_ID is not replaced in Info.plist

Hi everyone,

I'm experiencing an issue with Google Sign-In on iOS in FlutterFlow.

Setup

• FlutterFlow latest version

• Firebase Authentication

• Google Sign-In enabled

• Apple Sign-In enabled (working correctly)

• Local Run on a physical iPhone

• Firebase project connected successfully

Problem

Whenever I tap the Google Sign-In button, the app immediately crashes.

Xcode shows the following exception:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: 'Your app is missing support for the following URL schemes:
com.googleusercontent.apps.695462792732-a50gep42f6d52h0tipqcgmu5m6m1um7e'

What I found

In my generated ios/Runner/Info.plist, FlutterFlow creates:

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleTypeRole</key>
    <string>Editor</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <!--FF_REVERSED_CLIENT_ID-->
    </array>
  </dict>
</array>

The placeholder FF_REVERSED_CLIENT_ID is never replaced with the actual value from Firebase.

Thanks in advance!
