Column and ListView documentation should talk about the "expand or scroll" use case #35753
Description
We have some sample code in SingleChildScrollView that talks about the "expand or scroll" and "center or scroll" cases. There's a link to it from Column, but even I, who added the link, missed it just now when scanning through. We should also have similar examples at ListView showing how to do this kind of thing in the more general "infinite list" case. For example, we should show the use case of "align a button to the bottom of the viewport unless it can scroll in which case pin it to the bottom of the list" (presumably this should be possible using SliverFillRemaining). And the SingleChildScrollView docs should probably have an animation showing what it looks like, next to the sample code.

/cc @Piinks The generic example should be possible with the fix you're working on for SliverFillRemaining, I think.

I think we are planning work for some new widgetry in this area to make for an easier experience. I'm going to un-assign myself for now as I won't be able to circle back right away.
