I have `LazyVerticalGrid` with `itemsIndexed` over...

# compose

I have LazyVerticalGrid with itemsIndexed over a property which is mutableStateListOf . Everything is working fine when I add items, but when I remove items via remove or clear on that list I get an exception trying to access non-existing items. It’s a call from inside the itemsIndexed , looks like it didn’t notice collection has changed. Is it a known issue or am I doing something wrong?

Same with items

[orangy]

The code is pretty trivial

LazyVerticalGrid(GridCells.Adaptive(72.dp)) {
            itemsIndexed(inventory.items) { index, it ->
                Text("${it.thing.name} [${it.amount}]")
            }
        }

and

class Inventory() {
    val items = mutableStateListOf<InventoryItem>()

Yeah I've seen this exception in Slack a couple times.

I see, thanks. @Andrey Kulikov is it yours? 🙂

Reproducable with desktop compose 0.3.0-rc1, not sure which compose is bundled

[Andrey Kulikov]

hey! yes, sorry it is not yet fixed, but I have plan to fix it in upcomming releases. please consider using mutableStateOf immutable lists for now

Is there a public issue to follow?

[orangy]

Yes, I’m using mutable state of immutable list now, it works fine. Thanks.

I see this issue is marked as fixed, but how do I know if it were already released in some public build? And if it also went to compose-desktop?

[Andrey Kulikov]

it was released in beta02 of the android build and in the first desktop release created after 3th of March(basically the latest one should contain it)

It'd be so nice that Google's issue tracker shows in a public metadata-field what releases will first include a given fix.
