``` var toReturn PixelArt = null CoroutineScope <http Dispat kotlinlang #coroutines

var toReturn: PixelArt? = null

    CoroutineScope(<http://Dispatchers.IO|Dispatchers.IO>).launch {
        AppData.pixelArtDB.pixelArtCreationsDao().getAllPixelArtCreations().observe(this@extendedGetCurrentPixelArtObj.findViewTreeLifecycleOwner()!!) {

    return toReturn!!

One way would be to convert your livedata to flow, it should be available in some livedata-ktx androidx artifact https://developer.android.com/reference/kotlin/androidx/lifecycle/package-summary#(androidx.lifecycle.LiveData).asFlow() then you need to use

dao.liveDataQuery().asFlow().first()

BUT, you use Room, which natively supports coroutines, so you can simply switch from

LiveData

Flow

, or to simply

suspend

function

I believe Room supports

Flow

. There is no need to return a

LiveData

simple to convert it to a

Flow

. Google has a CodeLab that teaches you how to use Room and Flow. Check Respond to data changes using Flow.

When using room you should prefer declaring a separate suspend DAO function instead of using .first on a flow from it. The flow sets up database change observers that are wastefully discarded immediately when you use .first with them
