You're missing a syncRenderObject function.  Looks like ClipRect and ClipOval
are missing them too.  Padding is a good class to use as a template here.

ClipRect and ClipOval are missing them, but RenderClipRect and RenderClipOval
have no members to sync. Should I have a sync method anyway for consistency?

 class ClipOval extends OneChildRenderObjectWrapper {
   ClipOval({ String key, Widget child })
     : super(key: key, child: child);
