Can boxy deal with adjusting listview position when an item changes height? about boxy

Hey, sorry for the late response!

Unfortunately, boxy can't circumvent these errors during layout

I think a possible workaround in your case is to do this scroll adjustment outside of the layout phase, i.e. listen to the underlying ImageProvider, enumerate the children of the ListView (via a GlobalKey), determine if an adjustment is necessary using the RenderBox's sizes / positions, and then finally do the adjustment

Thanks for the concept, this is very helpful. In the way I'm imagining what you are saying, do you think there will be a visible 'glitch' between the time the image provider renders the image and then an adjustment is made using the render box size?

When the ImageProvider completes, it notifies every listener at the same time, so the scroll adjustment should happen on the same frame as the image being painted for the first time
