Description

I am writing an app that loads more than 400 PNGs into a scroll view.

But, it seems that VRAM is out of memory because too many images are being loaded.

I want to unload images outside the rendering range of the scroll view. Is there a way to know the display status of children elements in scroll view?

Contributor guide

Research direction
Understand the widget lifecycle in iced, specifically how scrollable works. Check if there's an existing method to detect visibility or bounds of children. Consider implementing a lazy loading mechanism for images outside the viewport.
