我有一个 MVI 架构，其中包含主屏幕的活动

class MainActivity : ComponentActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent {
      MyTheme {
        val viewModel: MainScreenViewModel = viewModel(factory = MainScreenViewModel.Factory)
        val state by viewModel.viewState.collectAsState()
        MainScreen(state, viewModel::handleEvent)
      }
    }
  }
}

主屏幕看起来有点像这样：

@Composable
fun MainScreen(state: MainScreenState, onEvent: (Event) -> Unit) {
  TaskList(
    tasks = state.items,
    onEvent = onEvent,
  )
}

@Composable
fun TaskList(tasks: List<TaskState>, onEvent: (Event) -> Unit) {
  LazyColumn {
    items(items = tasks, key = { it.id }) {
      Task(state = it, onEvent = onEvent) …
