Is there a way to write @Composable functions after async calls?

it’s not clear to me what you’re asking. what is it you’re trying to do?

Hi Leland.
I have the code bellow:

private fun bind() {
        disposables.add(viewModel.states().subscribe(this::render))
        viewModel.processIntents(intents())
    }

    private fun render(state: ItemsViewState) {
    }

I want to know how I could call a composable function into render, I know that the composable functions can only be called from another composable or setContent function.

what you want to do instead is set up your composable functions to render things based on some stateful piece of data using the state { … } composable. Then when you subscribe to vviewModel.states() you can update that value which will cause a recomposition.

for instance, you could do something like this:

@Composable fun ComposeState(state: ItemsViewState) { ... }

setContent {
  val x = state<ItemsViewState?> { null }
  onActive {  viewModel.states().subscribe { x.value = it } }
  x.value?.let { ComposeState(it) }
}

Something like that. There are lots of different ways to do this, some better than others depending on the context, but hopefully this can get you started?

I see. I appreciate your help!
I'm going to read about state and onActive.
