AngularDart does not handle expressions with optional parameters correctly

[mvuksano]

If there's a component which has the following html

<div ng-click="ctrl.doSomething(true, content:'test')">Hello</div>

And dart part as:

import 'package:angular/angular.dart';

@NgComponent(selector: 'my-component',
    templateUrl: 'component/my_component.html',
    publishAs: 'ctrl')
class MyComponent {
  showSomething(something, {content}) {
    print("SOMETHING: ${something}");
    print("CONTENT: ${content}");
  }
}

The parser doesn't handle this scenario correctly. It treats content part in the above expression as AccessScope, which sounds incorrect. The message that I get is:
"Parser Error: Missing expected ) at column 33 in [ctrl.showSomething(true, content:'test')]"

I checked codes. I don't know it's a bug or a spec but currently angular.dart does not support named parameters in templates. Corresponding parts of the code are:
https://github.com/angular/angular.dart/blob/master/lib/core/parser/dynamic_parser_impl.dart#L205-L207
https://github.com/angular/angular.dart/blob/master/lib/core/parser/dynamic_parser_impl.dart#L274-L282

@technohippy is correct. Named parameters are not currently supported in Angular expressions.

Should be fixed soon by #762
