Execution failed for task ':sms:verifyReleaseResources' while building APK of flutter application - flutter

Question

I'm trying to build APK of my flutter application but upon running flutter build apk --split-per-abi I'm getting below error.
It looks like there is something wrong with the camera package and I don't know what sms:verifyReleaseResources is referring to. I have tried different verisons of camera package but in vain.
Did any one else encountered this issue before?
I have followed this guide to build an apk
https://flutter.dev/docs/deployment/android
D:\CIIT GUIDE\Flutter\Apps\storeifie_new_admin_panel>flutter build apk --split-per-abi

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve
the incompatibility.

I was able to solve this problem by simply removing below packages from pubspec.yaml
otp: ^2.2.3
