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:

"IllegalStateException: CompositionLocal LocalDensity not present

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! 🙏
