compose-multiplatform VS skiko

So, to add file associations, we need to be able to pass both the .properties file and the --file-associations option. At the time of writing this article, the org.jetbrains.compose plugin doesn't provide such a mechanism. There is an open issue on GitHub that describes a possible workaround, which, unfortunately seems to not work on macOS.

JetBrains has a simplified example of a general-purpose Compose text viewer here: https://github.com/JetBrains/compose-multiplatform/blob/master/examples/codeviewer/shared/src/commonMain/kotlin/org/jetbrains/codeviewer/ui/editor/Editor.kt


Compose for desktop has a scrollbar component available. You probably can't use that directly on Android, but you could probably steal most of its code.

My company uses https://github.com/JetBrains/compose-multiplatform to make a desktop app in Kotlin. It's amazing and fantastic. It's basically as mature as using Kotlin in an Android app.

Kamel is an asynchronous media loading library for Compose Multiplatform.

Kotlin Compose Multiplatform is the way to do Desktop apps. https://github.com/JetBrains/compose-multiplatform

As for missing controls, a common one is a grid. They have built in grids, but again they are built for Android and don't make any sense in a desktop app. There is no simple way to create an Excel-like Data Grid like you might see in Windows Forms, although it can be done. https://github.com/JetBrains/compose-multiplatform/issues/344.

All I know is that they use skiko.

It built on a render framework named skia, JetBrains create a kotlin mapping which named skiko for it.

I was curious to give it a go but unusable on Gnome 42.5; the window lags so much that simply trying to drag to reposition it on the screen is impossible seems related an issue with Skiko and OpenGL reported here: https://github.com/JetBrains/skiko/issues/494

Fleet does not use Compose, but it does use Skiko[1], which also provides binding for Skia[2] (the native graphics library also used by Chrome & Flutter).

The main difference between the libraries is that Skija provides Java/JVM bindings for Skia, whereas Skiko provides Kotlin bindings for Kotlin/JVM, Kotlin/JS, and Kotlin/Native targets. Of course Skiko's Kotlin/JVM bindings can be used with other JVM languages, not just with Kotlin.

How about skiko?

JetBrains is moving from skija to skiko, but it could be interesting either way!

They Merged today the functions that will be usaged on Compose for opening, closing and handling text inputs https://github.com/JetBrains/skiko/pull/455 (if I understand correctly). Currently, the examples rely on xcodegen file, based on the currently plugin that Compose has for Desktop, it provide alot of things including packaging for desktop, I think they will provide a xcodegen file automatically and use xcodegen behind the scenes to generate everything needed.

https://github.com/JetBrains/skiko (a Kotlin MPP binding for Skia). Skiko Does not contain build for iOS. Now Skiko contains build for iOS, MAC arm processor via Kotlin/Native. So we can use Skiko for pure canvas rendering in all platform. It is matter of time they release compose for iOS. So UI also goes multiplatform.

But it does seem like the solution they're using for Fleet is different. Skia is the same graphics library used by Chromium and Flutter. I'll remain cautiously optimistic for now, but the quality of the text rendering and customization options will make or break it for me personally.
