Component used: SwipeToDismissBox Version used: 1.2.0-alpha09 Devices/Android versions reproduced on: emulator

Uncommenting backgroundScrimColor in the sample is a hack to make it work again.

    val items = remember { mutableStateListOf(1, 2) }

    val current = items.last()
    val previous = items.dropLast(1).lastOrNull()

    val state = SwipeToDismissBoxState()
    SwipeToDismissBox(
        state = state,
        backgroundKey = previous ?: SwipeToDismissKeys.Background,
        contentKey = current,
        hasBackground = previous != null,
        onDismissed = { items.removeLastOrNull() },
//        backgroundScrimColor = if (current % 2 == 0) MaterialTheme.colors.background else MaterialTheme.colors.error
    ) { isBackground ->
        val item = if (isBackground) {
            previous
        } else {
            current
        }

        Box(modifier = Modifier.fillMaxSize(), contentAlignment = Alignment.Center) {
            if (item != null) {
                StandardChip(label = "item $item", onClick = {
                    items.add(items.size + 1)
                })
            } else {
                Text("EmptyEmptyEmptyEmptyEmptyEmpty")
            }
        }
    }
