Is there a way to get the marker annotations (particularly @Immutable) in a separate, common artifact? I have some data definitions in a common module that doesn't have compose dependencies, and would like to mark them as immutable.

Define your own in common with @OptionalExpectation and then actual typealias in the Android source set

Unfortunately my compose module is entirely separate from the multiplatform module and consumes it via a dependency, so I don't have access to @Immutable even on the jvm source set. I could add the compose runtime as a dependency there and do it, but it's rather big and there should be an easier way imo.

I doubt if it will work without applying the compose compiler plugin. I don't think the compiler takes annotations of classes in other modules into account.

In such case, what if you would create typealias (that points to your state data class) in the module where you have compose and then annotate this typealias with @Immutable ? Later you just pass your state to Composable fun as the typealias you created. Not sure if that would work tho 🤔
