            new SliverSafeArea(
              top: true, 
              sliver: new SliverPadding(
                sliver: new SliverList(
                  delegate: new SliverChildBuilderDelegate(
                        (context, index) => ,
                    childCount: ....,

You need to set physics: BouncingScrollPhysics(), on your CustomScrollView for it to work. You should also change the builder of CupertinoSliverRefreshControl to something more Material, like this:

CupertinoRefreshControl(
    builder: Theme.of(context).platform == TargetPlatform.iOS
        ? buildAppleRefreshIndicator
        : buildAndroidRefreshIndicator,
    onRefresh: ...,
)

I did this on my app and here's a gist with both refresh indicator methods.

thank you! all works now

@gildaswise Reopen. If SliverList have only one item refresh indicator not work(on iOS and Android too)

[gildaswise]

@AndreyTCR Is the List occupying all available space or is it only with the item's height? There might not be enough space for the RefreshIndicator to appear, or you are pulling from the middle of the screen instead of right in your list

@gildaswise problem, i think, on SliverList height. If we have 1 item on it then bounce not work correctly, but if we have more items(more i mean Sliverlist bigger then viewport) then all work correctly.

I changed the builder of CupertinoSliverRefreshControl to something by gist ，but it‘s still not working on Android @gildaswise

----2018/10/22 update----

You may not be able to swipe on an android device when physics is AlwaysScrollableScrollPhysics. But there's a pit here, you can't do pull-down refresh without the sub controller filling the screen if you
change AlwaysScrollableScrollPhysics to BouncingScrollPhysics. The following code can be pulled down in any case.

class RefreshScrollPhysics extends BouncingScrollPhysics {
  const RefreshScrollPhysics({ScrollPhysics parent}) : super(parent: parent);

  @override
  RefreshScrollPhysics applyTo(ScrollPhysics ancestor) {
    return RefreshScrollPhysics(parent: buildParent(ancestor));
  }

  @override
  bool shouldAcceptUserOffset(ScrollMetrics position) {
    return true;
  }
}

FYI: I just found out the official example flutter_gallery --> Cupertino --> Pull to refresh does not work on my Android today. I am not sure if this is the same issue.
