I imagine this is a fairly simple thing to figure out, but I'm not seeing it in the docs. If I have a task that takes 2 parameters, but also needs to wait until the completion of a task that doesn't return anything, how I do signal that dependency?

with Flow as f:
   x, y = func_1():
   no_return_func():
   res = final_func(x,y)

Using the example above, how do I signal for

final_func

to wait on

no_return_func

? Do I just add a third argument to the function and have

no_return_func

return

True

? Or is there a cleaner way?

Cool, so it's a no go in the functional api?

They don't need to return anything, but a task would in theory always return something, check this

The functional/imperative API can be mixed so it's okay if it's a no-go in the functional API generally
