标签: angular-dart-routing

我只是在阅读 AngularDart路由教程并遇到了这个代码片段。

import 'package:angular/angular.dart';
import 'package:angular_router/angular_router.dart';

import 'route_paths.dart' as paths;
import 'crisis_list_component.template.dart' as clct;
import 'hero_list_component.template.dart' as hlct;

@Injectable()
class Routes {
  static final _crises = new RouteDefinition(
    routePath: paths.crises,
    component: clct.CrisisListComponentNgFactory,
  );

  static final _heroes = new RouteDefinition(
    routePath: paths.heroes,
    component: hlct.HeroListComponentNgFactory,
  ); ..... see routing tutorial link above.
}

有什么作用

import 'crisis_list_component.template.dart' as clct;
import 'hero_list_component.template.dart' as hlct;

实际导入？
