Yes. Probably that’s the problem. I don’t see any fast solution for solving this with MutableStateFlow. Probably simply MutableStateFlow is not the correct class to use in this case

I change an attribute of a list’s element and re assign the changed list

Do the items in the list implement equals taking that changed attribute into account?

[Dario Pellegrini]

Those items are instances of data class that if I remember correctly automatically implements equal using its own attributes

[Dario Pellegrini]

data class SelectionWrapper<T: Any>(val value: T, var selected: Boolean)

[wasyl]

And you’re saying you have

val list = listOf(selectionWrappers)
mutableStateFlow.value = list
list[0].selected = true
mutableStateFlow.value = list

and the new list is not emitted?

[Dario Pellegrini]

Yeah

[Dario Pellegrini]

Wait I send you an example

[Dario Pellegrini]

val mutableStateFlow = MutableStateFlow(arrayOf<Person>())
fun start() = CoroutineScope(Dispatchers.Main).launch {
    mutableStateFlow.onEach {
        Log.i("MutableStateFlow", "$it")
    }.launchIn(this)

    mutableStateFlow.value = arrayOf(Person("Dario", "P"))
    delay(1000L)
    val array = mutableStateFlow.value
    array[0].name = "Da"
    mutableStateFlow.value = array
}

data class Person(var name: String, val surname: String)

[Dario Pellegrini]

With more simple class
