This is the key thing in the demo. By specifying the bottom occlusion value, the list will automatically adjust the content insets and scroll indicator insets while also respecting the keyboard adjustments the list already provides.

Behavior.occlusionInsetsso Listable can account for persistent UI that visually covers the list viewport, such as a floating bottom action bar.Key changes:
Behavior.occlusionInsetsas a semantic inset for persistent viewport occlusion.layout.bounds.padding, which continues to control Listable content layout.Why not
customScrollViewInsets?customScrollViewInsetscan model this, but it requires clients to own the full keyboard and overlay inset calculation.occlusionInsetskeeps the common persistent-overlay case on Listable's standard keyboard avoidance path while still leaving.customavailable for screens that need full control.Demo
