@jw Whats your opinion about Flutter?

Not sure how this is related to Kotlin

Flutter = Java Swing. React-Native = Java AWT

Comparing with Kotlin Native, I am a Kotlin Native enthusiastic but I see a good potential in Flutter to cross platform development

For a cross platform UI solution Flutter is the best out there in my opinion. Its better than React Native. @Diefferson I think your referring to Kotlin Multiplatform. Kotlin Native , is used to compile Kotlin to native binaries. But its approach to cross platforming is more of sharing Logic across platforms. So it depends on which school of thought you like, and the use-case you want it for
