fun onUnplaced(): Unit

This method is called when the layout was placed earlier, and is not placed anymore. It happens when some of the parents still compose this child, but don't place a corresponding androidx.compose.ui.layout.Placeable, or when this child is completely removed from the tree after being placed earlier. Not placed children are not drawn and doesn't receive pointer input events.

Those apis could be used to be notified when the layout is placed:

registerOnLayoutRectChanged
GlobalPositionAwareModifierNode.onGloballyPositioned
LayoutAwareModifierNode.onPlaced
Reacting on a non-null androidx.compose.ui.layout.Placeable.PlacementScope.coordinates from a LayoutModifierNode placement block.
