Can we mutate the items list being passed in to the

LazyColumnFor

? Like adding or removing items and expect the changes to be reflected in the

LazyColumn

? Something like

adapter.notifyDatasetChanged()

we used to do with

RecyclerView

Yes but you need to use:

val list: SnapshotStateList<YouDataType> = mutableStateListOf()

When you change this list using add, remove, ... the UI will refresh automatically

Okay! So it'll just recompose that single add/remove right? Or it'll recompose the entire

LazyColumn

I'm concerned whether there are any performance hits by doing so?

I am not sure how exactly this is implemented in the LazyColumn/LazyRow. But currently this is the only way i am aware of to change the content dynamically without refreshing the complete list.

I have used both and

SnapshotStateList

does granular updates,

State<List<...>>

does not.
