As mentioned already, there is AngularDart, but we also have a full port of Polymer to Dart, so you can write web components in Dart.

We also have Dart packages for the Polymer project's core-elements and paper-elements (Material Design, nee Quantum Paper) that were announced at I/O.

Web components and Dart is a really powerful combination for apps.

It has AngularDart, an official port of AngularJS to Dart. Seems promising, will try it if and only if Dart gets native support in Chrome.

You mean like https://angulardart.org/

Yes, it has AngulartDart.
