# compose

I'm playing with the new LookaheadLayout , and it crashes if there is LazyColumn inside `LookaheadLayout`'s content:

java.lang.IllegalStateException: subcompose can only be used inside the measure or layout blocks

Is it not supported yet, or am I doing something wrong?

Don't know if it is supported yet, can you file a bug against LookaheadLayout to confirm/track the issue?

Thanks! Filed https://issuetracker.google.com/issues/240016022

I believe LookaheadLayout currently explicitly does not support subcomposition, but I'm not sure it's expected to crash.

Thanks for filing the issue. SubcomposeLayout isn't supported yet. It's mentioned in the kdoc. I'm currently working on building the support. 🙂
