Now you can use the built-in pullRefresh modifier.

Something like:

val refreshScope = rememberCoroutineScope()
var refreshing by remember { mutableStateOf(false) }

fun refresh() = refreshScope.launch {
    refreshing = true
    //...do something
    refreshing = false
}

val state = rememberPullRefreshState(refreshing, ::refresh)

Box(Modifier.pullRefresh(state)) {
    LazyColumn(Modifier.fillMaxSize()) {
        if (!refreshing) {
            items(itemCount) {
                //...
            }
        }
    }

    PullRefreshIndicator(refreshing, state, Modifier.align(Alignment.TopCenter))
}

To create a swipe-to-refresh layout, we need to add dependency in buld.gradle which will provide swipe to refresh layout just like SwipeRefreshLayout in traditional android.

  implementation 'com.google.accompanist:accompanist-swiperefresh:0.24.13-rc'

..

To create this kind of layout we require two APIs one SwipeRefresh for layout and another rememberSwipeRefreshState which will remember the state.

@Composable
fun SwipeRefreshCompose() {

    var refreshing by remember { mutableStateOf(false) }
    LaunchedEffect(refreshing) {
        if (refreshing) {
            delay(3000)
            refreshing = false
        }
    }

    SwipeRefresh(
        state = rememberSwipeRefreshState(isRefreshing = refreshing),
        onRefresh = { refreshing = true },
    ) {

       // list view

    }

}
