childrenInPaintOrder property
override
Provides an iterable that walks the children of the viewport, in the order that they should be painted.
This should be the reverse order of childrenInHitTestOrder.

@override
Iterable<RenderSliver> get childrenInPaintOrder sync* {
if (firstChild == null)
return;
RenderSliver child = firstChild;
while (child != center) {
yield child;
child = childAfter(child);
}
child = lastChild;
while (true) {
yield child;
if (child == center)
return;
child = childBefore(child);
}
}
