What is the most efficient way to understand coroutine in another script finished its job?

Question

Hello, I am callling a coroutine from another script. But caller script must to do somet$$anonymous$$ng when t$$anonymous$$s coroutine finishes its job. What is the most elegant, modular and efficient design for that purpose.

I can use boolean or interface but they don't seem like a good design.

I thought broadcast message but I have never used them and I don't know their efficiency.

You can yield the coroutine from the caller, like so:

 // ....
 StartCoroutine(FirstClassCaller());
 // ...

 IEnumerator FirstClassCaller() // Has to be a coroutine itself
 {
     Debug.Log("Starting.");
     yield return OtherClassCoroutine(); // Start the coroutine and wait for it to finish
     Debug.Log("Other coroutine just finished.");
 }
 
 IEnumerator OtherClassCoroutine()
 {
     Debug.Log("Waiting.");
     yield return new WaitForSeconds(5);
 }

If you need somet$$anonymous$$ng executed after a certain time known by one script but not by the caller, you could just pass the method with it as a callback:

 public IEnumerator DoAndExecuteLater(System.Action callback){
 yield return new WaitForSeconds(5f);
 if (callback != null)
 callback();
 }
 
 StartCoroutine(DoAndExecuteLater(FunctionToCallLater));

It seems like a good approach. However I shouldn't change coroutine interface. But thanks anyway. I will keep it in my mind.
