I am trying to understand how coroutines work

While collecting stateFlows in Android, something stuck in my mind.
How should I write my code?

I have a StateFlow in my ViewModel like this:

I made a coroutine to update the value of a variable, but it doesn’t work:

I’m working on a Android project using coroutines and I have a sequence of operations that involve both IO-bound and CPU-bound tasks. Here’s what my process looks like:

I am trying to make a function called once every 100 milliseconds. I want to start immediately and than throttle every 100 millis, and also take the last value after the last 100 millis. Can someone provide a code that works?

I have a code block like so

So, I have a FragmentA. It contains a RecyclerView. It shows the list of items as expected at first. Now, when user clicks on one of the item, we navigate to FragmentB (FragmentA still in backstack). When user presses back, the backstack pops and now, we’re on FragmentA but, now, the RecyclerView is empty.
