AcxImperativeViewUtils class

A single entrypoint library for working with highly dynamic views in Angular 2 code. This allows easier refactoring and migration of approaches as the Angular team iterates and a standard API for AngularDart components to use.

Example use (see imperative_view_test as well): @Component( selector: 'imperative-list', properties: const 'items' ) @View( template: '', renderer: '' ) class ImperativeListComponent { final AcxImperativeViewUtils _imperativeViewUtils; final ElementRef _elementRef; final _listElement = new Element.ul();

  ImperativeListComponent(this._imperativeViewUtils, this._elementRef) {
    _dynamicViewUtils.useAsImperativeView(_elementRef, _listElement);
  }

  set items(List<String> items) {
    _listElement.children.clear();
    items.forEach((item) {
      final itemElement = new Element.li();
      _imperativeViewUtils.insertAngularComponent(
          ItemComponent,
          _elementRef,
          itemElement).then((ComponentRef componentRef) =>
              componentRef.instance = item);
      _listElement.append(itemElement);
    });
  }
}

@Component(
  selector: 'item',
  properties: const [
    'value'
  ]
)
@View(
  template: '{{value}}'
)
class ItemComponent {
  String value;
}
