Flex Mixin polymer iron does not work, but classes do

I got Polymer iron-flex-layout for working in my AngularDart component using classes. Since it generates an obsolescence warning, I thought I would try an alternative alternative: mixin's. They do not work.

I currently have this import in my artist_component.dart file:

import 'package:polymer_elements/iron_flex_layout.dart';

I also tried adding this to my index.html

    <link rel="import" href="packages/polymer_elements/iron_flex_layout.html">

This is different from the example in the documentation that uses the gazebo. In my artist_component.html, I have:

<style is="custom-style">
  .container {
   @apply(--layout-horizontal);
  }
  .flexchild {
    @apply(--layout-flex-3);
  }
  .flexchild-2 {
    @apply(--layout-flex-9);
  }
</style>
<section class="container">
  <section class="flexchild gutter">
...

I tried putting import in index.html and in my main css file along with no affect style. Given that classes work, you think mixim will be there too.
