Question

我有一个AngularDart应用程序，可以使用Javascript在Chromium和Chrome上正常运行。但在Firefox和IE中，我收到以下错误：

[14:36:14.648] "NullError: receiver.webkitCreateShadowRoot is undefined

这是我的foobarUI / pubspec.yaml：

name: foobarUI
description: A sample web application
dependencies:
  angular: 0.9.3
  browser: any
  json_object: any
  petitparser: any
  unittest: any
  foobar:
    path: ../foobarLib

我尝试添加js，shadow_dom和web_ui模块，但没有区别。

我试图添加“useShadowDom = true;” （和假）到主dart文件，没有区别。

从错误中可以看出，缺少对DOM shadow root的webkit支持，但为什么这个模块没有处理呢？

angular.dart.tutorial chapter_03示例发生同样的错误。这显然是Angular.Dart的一个问题。 Bug提交为：https://code.google.com/p/dart/issues/detail?id=15752

已经修复了Dart bug还没有被推到AngularDart。该作品被https://github.com/angular/angular.dart/issues/366阻止。

Firefox上的AngularDart失败，“receiver.webkitCreateShadowRoot未定义”
