I'm using launchInComposition as shown here to call suspend function....what's recommended way to show progress indicator (like CircularProgressIndicator) until that function completes?

@Composable
fun MainLayout(sdk: SpaceXSDK) {
    var launches by remember { mutableStateOf<List<RocketLaunch>>(emptyList()) }

    launchInComposition {
        launches = sdk.getLaunches(false)
    }
    
    LazyColumnFor(items = launches) { launch ->
        LaunchView(launch)
    }
}

actually looks like JetNews sample has something very similar to what I need (with their launchUiStateProducer)

[Halil Ozercan]

if you are looking for a really simple solution, you can always add a remember { mutableStateOf(true) } and update that state once your calculation is completed in launchInComposition

[Halil Ozercan]

something like

var isLoading by remember { mutableStateOf(true) }

launchInComposition { 
   ...
   isLoading = false
}

if(isLoading) {
    CircularProgressIndicator()
}

this is what I ended up doing - https://github.com/joreilly/kmm-networking-and-data-storage/blob/392cd9db8ee01bc073b3b9c4c472e592037597fd/androidApp/src/main/java/com/jetbrains/handson/androidApp/MainActivity.kt#L48
