Combine Kotlin Unit flows without transform function

Question

I have currently two SharedFlows that I need to combine to do something, but I don't really need the result from the transformation function, I only want to know if both "events" started yet. While implementing this I get this useless bracket body:

combine(
  flow1, // SharedFlow<Unit>
  flow2, // SharedFlow<Unit>
) { _, _ ->

  // Useless function body

}.onEach {
  // Do some work
}.launchIn(scope)

Is there a way I can do this more cleanly without the need for the transform function?

You can "Do some work" in "Useless function body" instead of `onEach`. — Sergio, May 24 '22 at 13:21
I think that might work, yeah. I'm going to try that out. Could you make this a response so I can mark as solved if it works correctly? — Pedro Romano Barbosa, May 24 '22 at 13:28
