Raw error message exposed on SignInScreen widget on ios Simulator

[lkpiel]

When I run my flutter app that uses the SignInScreen component from flutter_ui_auth on an ios Simulator, I see raw error messages on the simulator when entering for example wrong credentials. When I run the same app in Android emulator it shows the handled version of it: "The supplied auth credential is incorrect, malformed or has expired".

I ran the app in release mode on a physical ios device, but I still see the raw error message. I didn't see any references to it in documentation so I'd like to understand if these raw errors are only somehow exposed in development or would they appear when I would actually release the app as well ? Is there a way to handle these errors on an ios Simulator ?

This is the ios device error I am getting:
