Is there a recommendation on how to implement filtering in a LazyColumn?

[Chris Fillmore]

(code example forthcoming)

[Chris Fillmore]

class SomeItem(val isFavourite: StateFlow<Boolean>)
...

val items: List<SomeItem>
val filterByFavourite by someViewModel.filterByFavourite.collectAsState()

LazyColumn {
  for (item in items) {
    // Can't do this, not in @Composable context
    val isFavourite by item.isFavourite.collectAsState()
    if (filterByFavourite && isFavourite) {
      item {
        // show the item
      }
    }
  }
}

Is there something wrong with doing the below:

[Chris Fillmore]

item {
      val isFavourite by item.isFavourite.collectAsState()
      if (filterByFavourite && isFavourite) {
        // show the item
      }
    }

[Chris Fillmore]

In the second example, we would end up with empty `item`s being filtered out

Thanks for any advice!

Now that I think of it, better to do the filtering of the collection in the ViewModel
