Hi everyone 👋

I have spend the last few days working on an implementation for a Timetable/Calendar view in Jetpack Compose with a free scroll functionality (so being able to scroll in all directions)

FreeScroll Library: https://github.com/chihsuanwu/compose-free-scroll/tree/main
For the CalendarView I am greatly inspired by https://github.com/drampelt/WeekSchedule.

I have managed to get it working, though currently I am using a Layout composable just like the "WeekSchedule" app (BasicSchedule.kt) does (with some minor adjustments).
What I have noticed is that when I have a lot of Events, the scroll seems to get laggy. This lagg is mostly visible in Debug mode (I know that Jetpack Compose optimises a lot in release). Though that got me wondering...

Is there a way I can manually recycle/lazily render placeables in a Layout dependening on if they are even visible on the screen or not?

I read about SubcomposeLayout but I am not sure how to use it at this point in time

Hey 👋
I have been working on something quite similar a few months ago.
Mine solution however was based on LazyLayout to recycle items, you could check it for an inspiration:

Funnily enough, I actual found your library and looked into the code which got me on the right track! I managed to also get it working using a LazyLayout (without your library though)

I did however give you a star as it is an amazing library imo
