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

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

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.

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

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.
<@URLRR3Z4N> mentioned it above.

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.

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