hi, is there a way to get data from onGloballyPositioned modifier only once? I have an Image composable (which is zoomable) and I need to get its initial width and height, but I don't want to update it when I zoom. Here's how I'm getting image's width and height on the device screen right now

.onGloballyPositioned { layoutCoordinates ->
    imageHeight =
        with(localDensity) { layoutCoordinates.size.height.toDp() }
    imageWidth =
        with(localDensity) { layoutCoordinates.size.width.toDp() }
}

And I'm using them in an offset calculation like this

val offsetTop = windowInfo.screenHeight.minus(imageHeight).div(4)
val offsetStart = windowInfo.screenWidth.minus(imageWidth).div(4)

I think you wrap it in a BoxWithConstraints and it gives you width and height

I'll give it a try, thank you very much!

@Tgo1014 maybe I'm doing something wrong, but box's max height param is not giving me image's height, even though I'm using "wrapContentSize" modifier

max height is returning screen's height in dp
