implementing Jetpack Compose and RecyclerView integration for dynamic item updates
I'm writing unit tests and I'm experiencing an scenario where my Jetpack Compose UI is not reflecting updates made to a RecyclerView's data source correctly. I have a ViewModel that fetches data from a REST API and stores it in a mutable list. I then convert this list into a state that the Compose function can observe. However, when I update the data in the RecyclerView, the corresponding Composable does not update as expected. Here’s a simplified version of my setup: ```kotlin class MyViewModel : ViewModel() { private val _items = mutableListOf<Item>() val items: List<Item> get() = _items.toList() fun fetchData() { // Simulate a network call _items.add(Item("New Item")) } } ``` In my Composable function, I'm using a `LazyColumn` to display the items: ```kotlin @Composable fun ItemList(viewModel: MyViewModel) { val items by remember { mutableStateOf(viewModel.items) } LazyColumn { items(items) { item -> Text(text = item.name) } } } ``` However, after calling `fetchData()` in my ViewModel, I do not see the new item displayed in the UI. I've tried different approaches, such as using `mutableStateListOf` for the items list, but that led to other issues when interacting with the RecyclerView. I also considered that the question might lie in how I'm observing the data. If I modify the list directly, the Compose function doesn’t recompose. Should I be using a state holder like `mutableStateListOf()` or `StateFlow` for this scenario? What’s the best practice for integrating Jetpack Compose with RecyclerView data? I'm running this on Android 12 with Compose version 1.1.1. Any insights would be greatly appreciated! For reference, this is a production desktop app. How would you solve this?
