I try this next once, I have the build bot green again

+class LinkFactory {
   factory Link(head, [Link tail]) {
     return new LinkEntry(head, (tail === null) ? const LinkTail() : tail);
   }
 
   factory Link.fromList(List list) {
     switch (list.length) {
       case 0:
         return const LinkTail();
       case 1:
         return new Link(list[0]);
