I wonder if there is an event when the component show up in the screen.
I mean, not the moment when the component is made, but the moment when the component start to appear the screen so that user can see the component.
For example, I made a long list. and I add the button after the list.
and I read through the list until the button show up!
then the event occurs because button show up in the screen!
is there such kind of event?
If there is not, is there suggestion to how to make it?
