在 android compose 中使用SwipeToDismiss和使用的正确方法是什么？LazyColumnalpha09

我的做法：

LazyColumn(
    modifier = Modifier.padding(6.dp),
    verticalArrangement = Arrangement.spacedBy(6.dp),
) {
    items(items = items) {
        TrackedActivityRecord(it.activity, it.record, scaffoldState)
    }
}

@OptIn(ExperimentalMaterialApi::class)
@Composable
fun TrackedActivityRecord(
    activity: TrackedActivity,
    record: TrackedActivityRecord,
    scaffoldState: ScaffoldState,
    vm: TimelineVM = viewModel()
){
    val dismissState = rememberDismissState()

    if (dismissState.value != DismissValue.Default){
        LaunchedEffect(subject = activity){

            val deleted = scaffoldState.snackbarHostState.showSnackbar("Awesome", "do it")

            if (deleted == SnackbarResult.Dismissed){
                vm.rep.deleteRecordById(activity.id, record.id)
            }

            dismissState.snapTo(DismissValue.Default)
        }

    }

    SwipeToDismiss(
        state = dismissState,
        background = {
            Box(Modifier.size(20.dp). background(Color.Red))
        },

    ) …
