Isn't it necessary to creep super () in the constructor when the class extends Sprite in actionscript3?

Question

I always do not call super () when I extend Sprite.
But is there a problem not calling super()?

So far, I have no problems, and I have never seen code that calls super () in a constructor whose class extends Sprite.

What about TextField?
I also have no problem with TextField.

How do I know if I should call super () or not?
