So, do you put previews in Android source only? (with hope it will work on the common code at some point)

[Vlad]

I forgot they exist for now

I use a Composable wrapper with a preview in Android and reuse the same Compose function from commonMain.

[Eugen Martynov]

Any example? Do you keep preview code in common?

Also worth to mention that in the Kotlin 1.9 change logs they mentioned that google takes implementation of the KMP plugin, I assume we just wait

For now we have preview only for Android and Desktop sourceSets.
For Desktop, here is the plugin: https://plugins.jetbrains.com/plugin/16541-compose-multiplatform-ide-support
But we are thinking about the possibility to add Preview to the commonMain sourceSet as well.

[Eugen Martynov]

I’m waiting but would like to have something already. Compiling and running on device is not the fastest feedback.

[Dima Avdeev]

Preview for iOS is not working for now.

But there is a workaround to use additional expect annotation in commonMain with actual on JVM sourceSet to render it as JVM Preview.
@Davgdafa mentioned it above.

[Eugen Martynov]

Aha! Thank you!

[Dima Avdeev]

We have an issue with adding the possibility to use Preview annotation in commonMain:
https://github.com/JetBrains/compose-multiplatform/issues/2045

And in Issue description author added a link to project with workaround.

You can check the example here:https://github.com/IlyaGulya/compose-jb/tree/example/common-desktop-preview/experimental/examples/falling-balls-mpp

I've moved GamePreview to common sourceSet and added stub androidx.compose.desktop.ui.tooling.preview.Preview annotation to trigger Compose Multiplatform IDE Support plugin to add gutter icon on GamePreview function.

Just to add to the list of weird and wonderful solutions: I've been keeping a previewMain source set, common to Desktop and Android, which get 'realised' with the correct annotations by wrapping functions in each platform. A bit of maintenance overhead but... It's common previews alright.
