ItemSnapshotList<T> data type support

How can I use ItemSnapshotList data type of shared part of kmp in swiftUI

[rickclephas]

Hi! Could you share some more details about the shared Kotlin code you are trying to use from SwiftUI?

Here are some details about the issue:
For overview: John O'Reilly's article on KMP Paging

Here is an adaptation from the article above:

private val SnapshotFlowHolder =
    HashMap<String, MutableStateFlow<ItemSnapshotList<AQUiModel>>>()

private const val PAGING_DATA = "PAGING_DATA"

private var PagingJob: Job? = null

private val AQPagingDataPresenter = object : PagingDataPresenter<AQUiModel>() {
    override suspend fun presentPagingDataEvent(event: PagingDataEvent<AQUiModel>) {
        SnapshotFlowHolder[PAGING_DATA]?.update { snapshot() }
    }
}

// ** THIS IS EXPOSED AS [Any] IN SWIFT **
@NativeCoroutinesState 
val AQViewModel.aqModelList: StateFlow<ItemSnapshotList<AQUiModel>>
    get() = SnapshotFlowHolder.getOrPut(key = PAGING_DATA) {
        // observableviewmodel.MutableStateFlow helper func
        mutableStateFlowOf(AQPagingDataPresenter.snapshot())
    }.asStateFlow()

fun AQViewModel.collectPagingData() {
    PagingJob = vScope.launch {
        state
            .flatMapLatest { it.entries }
            .collectLatest(AQPagingDataPresenter::collectFrom)
    }
}

fun AQViewModel.getModelAt(index: Int): AQUiModel? {
    return AQPagingDataPresenter[index]
}
