Hi there. I am trying to build an impression tracking SDK. To check if the

Composable

in the viewport, I am using a custom modifier with

onGloballyPositioned

method. Inside the lambda, am comparing the

x and y

cords of the

Composable

and compare it with window height/width. It works, but am wondering if there’s any better method/approach? 🙂

onGloballyPositioned

should generally be avoided (as much as possible) as it will be called a lot. It's kinda similar to

ViewTreeObserver.OnGlobalLayoutListener

which is invoked when any layout has happened. Feels like this would be better implemented as a

onPositionChanged

modifier, analogous to

Modifier.onSizeChanged

. That doesn't exist though.

@cb Okay. Do we have a ticket for this? or do I need to create one?

I don't have one 😄

Ohh.. i forgot 🤦‍♂️ ur not in the team anymore. @Leland Richardson [G] any idea?

Just raise a FR? This is probably a better question for @George Mount
