Check out Anko https://github.com/Kotlin/anko
Anko is an Android specific library that relies on the Android SDK. It makes no sense to consider porting it somewhere else because somewhere else you do not have the Android SDK since it is not Android.
yeah i get, i was thinking of something like flutter of Dart for Kotlin.
There are multiple projects going in that direction. So, sooner or later, there will be something like this. For now, it is not clear how it should look like, so feel free to join one of research projects.
Thank you, if you have links to some of the repository on similar research kindly share. Thank you
