Has anyone getting error java.lang.IllegalArgumentException: 0 was already used with subcompose during this measuring pass after beta01 when setting initialFirstVisibleItemIndex for LazyColumn? Full stacktrace in thread.

Are you using the same key for multiple items?

Seems like it is the problem, thanks!
I'm using Paging 3 with LazyColumn, and LazyPagingItems.get might return null if it is a placeholder, I might need to return a UUID instead of a 0 if it is a placeholder.

@Tlaster Can you file a bug? Mention what you did (duplicate key on LazyColumn), what error message you encountered (full stack trace) and that this error message was confusing.

you can also use index as a key for keys of placeholders. it just shouldn’t collide with real keys
