Setting up User Authorization to Google Calendar (iOS)

Custom Code

I can't get this custom code to return the AuthCode (which i subsequently need to fetch access and refresh tokens).


Both ChatGPT and below says I have to edit and add "reversed client ID"(from GoogleService-Info.plist) into the Info.plist file.

https://pub.dev/packages/google_sign_in_ios#ios-integration

Is this correct and the only solution is to to export Flutterflow code into Xcode? (I rather not have to manage FF code externally as I am not a developer and would need to rely on FF UI...)

Any suggestions? Thanks.

What have you tried so far?

I have check scopes and user email is registered in Google Cloud Console.
Build compiles correctly into iOS Test Flight
It successfully brings up the google sign in screen in my test iOS app
Tried all GPT (o1) suggestions. i.e. add signout first before signing back in etc.

Did you check FlutterFlow's Documentation for this topic?
Yes
