While Kotlin is a nice language, it doesnt come with a "hot code swap" feature. The goal of flutter was to making mobile development fun and fast again. Dart comes with the hot swapping feature. Changes to your code are shown in the app immediately. This is a big win! Try flutter for yourself to see how this is a major improvement over Java or Kotlin. If Kotlin has hot swapping it would be a good candidate. I do like Kotlin better than Dart, but Dart and kotlin look alike a lot. And to be honest, most code looks very similar. But development speed in Dart + Flutter is 10x faster than building an app in Kotlin for Android, and Swift in iOS.
