pub fn scroll_view_reader(
content: impl Fn(ScrollProxy) -> ViewHandle + 'static,
) -> ViewHandleExpand description
ScrollViewReader { proxy in content } — a scroll view that can be scrolled
from code.
The one view builder in SwiftUI that takes an argument the caller did not
supply. It is also escaping — …Vc in the mangling, not …VXE — so both
the closure and its context are leaked rather than borrowed: SwiftUI keeps
them and calls back long after this returns.
