Reasons for the lag of smooth scrolling on lazy column in android jetpack compose

I just use the lazy column for showing the my custom items on the view. I tried with this with itemsIndexed with as well. But lagging issue is not solved.

What can be the reasons for this?

Since you did not share any code anyone cannot give a specific reason for this to you but generally there are bunch of optimization tricks you can apply like:

• passing a unique key to your LazyColumn,
• running it in release build instead of debug
• if your "custom items" include an image, making sure the image library use use contains a cacheing mechanism
• using @Stable, @Immutableannotations in your ui state data classes etc.
