angularjs - Dart 中的手动注入(inject)

Question

如何在 Angular dart 中手动注入(inject)实例？这相当于 angularjs 中的以下内容:

var myInjector = angular.injector(["ng"]);
var $http = myInjector.get("$http");

组件内部的代码示例。

@NgComponent(
    selector: 'rating',
    publishAs: 'ctrl')
class RatingComponent {
  Injector _injector;
  RatingConfig _config;

  RatingComponent(this._injector) {
    _config = _injector.get(RatingConfig);
    // or
    _config = injectByName("RatingConfig");
  }

  void injectByName(String typeName) {
    _injector.types.takeWhile((Type e) {
      if (e.toString() == typeName) {
        _config = _injector.get(e);
        return false;
      }
      return true;
    });    
  }
}
