Hey everyone is `LaunchedEffect`'s block executed ...

# compose

[Son Phan]

Hey everyone is `LaunchedEffect`'s block executed together with composition phase, or after the composition phase is completed? I saw in the official docs, SideEffect is executed after the composition is completed, can't find the same info for LaunchedEffed.

LaunchedEffect(messages, lazyListState) {
   // In this block can I assume that "messages" and "lazyListState" are synced? Has "lazyListState" already had the info of current "messages"' items, such as itemCount,...
}

LaunchedEffect in any case launches a coroutine, which won’t run in the same frame as the first composition. Even what you do in there is not anything that is suspending itself

If either of those two keys change the old effect will just be cancelled and a new one will be scheduled to run, is that what you are worried about here?

[Son Phan]

This is basically what I am worried

LaunchedEffect(messages, lazyListState) {
   // In this block can I assume that "messages" and "lazyListState" are synced? Has "lazyListState" already had the info of current "messages"' items, such as itemCount,...
}

I'm still not sure what you're worried about, I replied about this right above.
You can run the app and log what you get in there to see what exactly you'll be seeing.

Thank you!
