[Flutter] Flutter app crashes for iOS build on startup

I am working on the application, where it was working in a proper manner. but later I did update the mac to macOS Monterey 12.2.1 and updated my iPhone device to latest 15.2 and Xcode 13.0 and used the latest one 13.2.1. But now the application runs crashes on startup or even after login with but there is which is driving me crazy.

Point is it does not work when building on xcode and it works fine when running from Android studio. So below are my specs that I am working on:
