Firebase Non Fatal/Fatal error tracking on my flutter custom SDK not on flutter app

I am looking for some one who can implement Firebase Non fatal/Fatal error tracking on my flutter custom SDK that doesn't have material app or run app. It will be used in another flutter app as dependency. Either it can be done in native code Swift or Object C/ Java or Kotlin or if you know of any way to use flutter itself to track my custom SDK Crashes when the other example app using my SDK has failure.

I will link my SDK in another app as pubspec.yaml as below
custom_sdk:
path: ../

I can give you sample flutter custom plugin SDK and flutter example app with integration. I need error reporting from my SDK not from example app. If you can implement it ping me. Thanks!
