Thanks for reporting this. #126 removes the plugin-owned Kotlin Gradle Plugin and migrates the plugin and example to Flutter 3.47, AGP 9, and built-in Kotlin. It has passed local package, example, build, publish, and Android device checks, as well as the full GitHub Actions matrix. The PR is open and green, but it has not been merged or released yet.

Thanks again for reporting this.
android_id 0.6.0is now live on pub.dev with built-in Kotlin and the Flutter 3.47 / AGP 9 migration. If you try it in your project, I’d be glad to hear whether the warning is gone for you.
