Is it possible for a compose web application to consume composables from a compose multiplatform Gradle module (with android, desktop, web, etc.)? I have been able to do this fine with Android and JVM, but not Web. When my web module tries to consume a simple composable from my common-compose module, I get:

here is a thread with a similar question - https://kotlinlang.slack.com/archives/C01F2HV7868/p1674443083908619


Short answer: HTML based Composables can't use the composables from compose.material, foundation, etc (canvas based) directly. There is no out of a box solution to combine HTML based with Canvas based right now, although it should be possible.

We introduced @ComposableTargetMarker some time ago which should help to avoid mixing stuff like that
Not sure if Web composables are using it yet, but maybe makes sense to add those if they are not :)

Right on. Thank you both so much! 🙏
