Hello guys I am having problem with my synchronous call, my use case is I wanted to finish all collection before launching doAnotherCall() , the viewModel.detailsState collects in a loop. I mean its emit and collect in a loop adding delay in doAnotherCall() does not help. Best Regards.

private suspend fun collectProductList() = withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
    viewLifecycleOwner.lifecycleScope.launch {
        viewModel.detailsState.collectLatest { state ->
            when (state) {
                is ItemDetailState.ShowLoader -> binding.progressBar.visible()
                is ItemDetailState.HideLoader -> binding.progressBar.gone()
                is ItemDetailState.OnSuccess -> handleSubListSuccess(state.list, state.details)
                is ItemDetailState.OnFailed -> handleFailure(state.error)
            }
        }
    }
    launch {
        doAnotherCall()
    }
}

Solve it by adding observable and emit the counter in every onSuccess then add logic if list size == counter size then call doAnotherCall instead of combining it to one scope.

What about just removing the 2 launch calls? If you want to do one thing and then the other, just do these 2 things without launching coroutines

Let me try and will let you know thanks.

You will of course have to make sure that the flow you collect is actually finite
