Simple example demonstrating how you might be able to use a delegated property with a flow in Kotlin, in response to a comment on YouTube here: https://www.youtube.com/watch?v=KFgb6l1PUJI&lc=Ugy1TJWi4MwXZOtTGOF4AaABAg. Warning - I'm not very experienced with Flow at this point, so there might be a better way to do this!

import kotlinx.coroutines.CoroutineScope
import kotlinx.coroutines.delay
import kotlinx.coroutines.flow.Flow
import kotlinx.coroutines.flow.collect
import kotlinx.coroutines.flow.flow
import kotlinx.coroutines.flow.onEach
import kotlinx.coroutines.launch
import kotlinx.coroutines.runBlocking
import kotlin.properties.ReadOnlyProperty
import kotlin.reflect.KProperty

fun createFlow(): Flow<Int> = flow {
    for (i in 1..100) {
        delay(100)
        emit(i)
    }
}

fun main() = runBlocking<Unit> {
    val latest by FlowLatest(createFlow(), 0, this)

    launch {
        for (i in 1..40) {
            delay(250)
            println(latest)
        }
    }
}

class FlowLatest<T>(flow: Flow<T>, initial: T, scope: CoroutineScope) : ReadOnlyProperty<Any?, T> {
    private var latest: T = initial

    init {
        scope.launch { flow.onEach { latest = it }.collect() }
    }

    override fun getValue(thisRef: Any?, property: KProperty<*>): T = latest
}
