Looking for guidance in using standard Polymer Core and Paper components (and associated events) in Dart Editor

Question

First of all many thanks for the incredible source of information that you are providing to people like me.

I am visiting this site very often and most often finding the answer I need, but this is this is the first time I post a question, so please accept my apologies if I don't fully conform to rules.

Here is my issue:

• I am "playing" with Dart Editor and Polymer to try to understand if I could use these technologies in my job moving forward
• I was able to import the Polymer Core and Paper components in Dart Editor and to install polymer.dart
• I was able to create a simple web page with a "core-selector" and to add some Dart code to handle a click on this component
• I can't find how to listen using Dart code for component-specific event ("core-activate" & "core-select" here) and how to read component-specific attributes ("selected" & "multi" here)
• I don't seem to be able to find good examples showing how to use "standard" polymer components in a web app created Dart Editor
• I could find material on how to create my own polymer components using polymer.dart but I would just like to use standard components

I understand both Polymer and Dart are young but I can't imagine the clever brains at Google not having a solution or plans on this.

Regards and many thanks again.

The problem is not that Polymer and Dart are young. Dart is quite mature, Polymer is not even beta but also not so young anymore. The problem are the core- and paper-elements. They are very new and developed in JavaScript and the Polymer.dart team just created a code generator that wraps the JS core- and paper-elements in Polymer.dart elements. This process is only available since a few days and there are several issues which are yet to be solved.

I think you should provide a concrete example in your question of what you can't get working. Basically Polymer.dart core- and paper-elements work exactly as other Polymer.dart elements. So it's hard to know what to explain.
