Hi, @Knightro63 !
I`ve done some changes to fix KGP warning from three_js_sensors.
Have a nice day.

WARNING: Your app uses the following plugins that apply Kotlin Gradle Plugin (KGP):  three_js_sensors
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
