Dart Polymer >= 1.0.0-x new PolymerDom(this).parentNode

See also https://www.polymer-project.org/1.0/docs/devguide/local-dom.html

Dart Polymer <= 0.16.x

@ShailenTuli is right about encapsulation should not be broken.

But also JS Polymer elements access the parent in their layout elements because it's still convenient in some scenarios.

This works now in PolymerDart too.

(this.parentNode as ShadowRoot).host
