@ravi84184 Thanks for your contribution.
I would highlight that this pull request should be a top priority as it is jeopardized by incoming flutter versions that will fail its build. I would be appreciated to have this PR reviewed and merged for this package to remain compatible with incoming versions of flutter.
Here is the error i am getting without having Kotlin migration plugin of this PR:
WARNING: Your app uses the following plugins that apply Kotlin Gradle Plugin (KGP): device_info_plus, package_info_plus
Future versions of Flutter will fail to build if your app uses plugins that apply KGP.

Please check the changelogs of these plugins and upgrade to a version that supports Built-in Kotlin.
If no such version exists, report the issue to the plugin. If necessary, here is a guide on filing
an issue against a plugin: https://docs.flutter.dev/release/breaking-changes/migrate-to-built-in-kotlin/for-app-developers#report-incompatible-kotlin-gradle-plugin-usage-to-plugin-authors

If you are a plugin author, please migrate your plugin to Built-in Kotlin using this guide: https://docs.flutter.dev/release/breaking-changes/migrate-to-built-in-kotlin/for-plugin-authors
