ReadonlynextReadonlystreamThe feed's items, one by one, as a lazy stream. A plain feed's stream gets
them by page requests from this instance's page on: each pull past a page's
last item is that page's nextPage — one page request, as the app sends it
— to the feed's end. A swipeable feed overrides it (ScreenSwipeMembers):
its stream is walked by swipes, as the app does. Nothing runs until it is
consumed; stopping, take or a failure requests no page beyond the one the
last pulled item came from.
The member a feed screen's handle gets — the feed's raw pagination, which every feed has, swipeable or not:
nextPage, which returns a new instance of the feed showing the page after the one it is asked of — one page request, exactly as the app sends it — and never changes the instance it is asked of;undefined, with nothing sent, when the answer said no page follows. The instance is typed as the handle it is called on.
