Dart2js warnings on pub build

[vadimtsushko]

Recently (I cannot trace when exactly) a started to get warnings in my project, which using bwu_polymer_routing

Library 'package:bwu_polymer_routing/module.dart' doesn't export a 'RouteHandle' declaration.
Try removing 'RouteHandle' from the 'show' clause.
    show RouteProvider, RoutingHelper, View, RouteHandle;

I'm on sdk 13.0
versions of:

• route_hierarchical 0.6.2
• bwu_polymer_routing 0.1.2
