Consider, if there is a ListView with a number of variable height Widgets which further contain network image's that load at their own pace.

When the images load, the height of each individual listview item widget will change (increase) appropriately

If this set of events occurs above the users current scroll position in the listview, then the content will shift / jump. The result is that the user is now looking at content that was formerly above their last viewed position.

This gives for bad user experience.

Is it possible to add a "scroll anchoring" option to listviews (or any scrollable view) that the scroll position should maintain itself relative to the bottom extent of the listview when a layout change occurs above the current position or vice versa when it occurs under neath the current position (as it is currently works). In this way from the user POV, there is not content jumping effect

In the HTML/CSS world this effect has sometimes been called Layout Jank (https://css-tricks.com/the-fight-against-layout-jank/) which has been addressed with various forms of scroll anchoring

In this case, it would apply to not just a webview but I guess anything that could be controlled by a ScrollContoller?
