Why am I getting a type error on the polymer.dart element?

I have some code:

// main.dart:
void main{
  initPolymer();
  var view = new ChatAppConsumer();
}

//chat_app.dart
@CustomTag('chat-app')
class ChatApp extends PolymerElement{
  ChatApp.created():super.created();
}

class ChatAppConsumer{
  final ChatApp view = new Element.tag('chat-app');
}

As far as I can tell, I have all my files that are linking correctly and I call initPolymer();

before I try to create my own tag, but I get a type error that HtmlElement ChatApp` returns new Element.tag('chat-app'); is not of type

, but I use this exact template in another package from I have it and it works great there. Has anyone come across something like this before?

initPolymer

not enough, you must pass a closure to initPolymer.run(() => ...)

which your Polymer-related code executes.

See how to implement basic function in polymer applications for details .

= polymer 0,16,0 //main.dart: empty function {initPolymer (), then ((zone) => zone.run (() {var view = new ChatAppConsumer ();})); }



<Polymer 0.16.0

// main.dart:
void main{
  initPolymer().run(() {
    var view = new ChatAppConsumer();
  });
}
