Ask HN: How is Kotlin and Compose multiplatform over flutter?

I've used flutter to develop several self-user apps in both Desktop (Macos/Windows) and iOS platforms, and I just know about the Compose multiplatform using Kotlin. I knew flutter has been around for quite a few years and thus is quite mature & wildly used, but I really like the Kotlin programming language. I wonder how is Compose vs flutter, will it be a "future star" and beat or play with flutter in the same arena? Has any one experienced with Compose and could you share some opinions?
