unity – How one can distinguish pointer up inside button vs drag-out

I’m making a unity cellular sport, I’ve a easy scene and a canvas with just a few buttons and these buttons have scripts that detect if the button was pressed and launched. Right here is the code for doing this:

public class InteractiveButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
{ 
      
    public void OnPointerDown(PointerEventData eventData)
    {
        //do one thing
    }

    public void OnPointerUp(PointerEventData eventData)
    {
        //do one thing
    }
}

This works completely advantageous as when i press the button the down occasion will get triggered as anticipated, but when i preserve my finger pressed and drag my fingers off the bounds of the button and let go the OnPointerUp technique nonetheless will get referred to as as if I let my finger go on the button.

So how can I detect if the participant lets exit of the buttons bounds?
