Dart编辑器：原始示例web应用程序（使用聚合物）：编译错误

我已安装以下版本： Dart编辑器1.1.3.0版发行版（稳定版） Dart SDK版本1.1.3 我使用polymer库创建了一个新的web应用程序。该应用程序是带来编辑器的原始示例：clickcounter。我没有添加或删除任何内容。应用程序工作正常，没有错误。但是当试图编译时，会出现很多错误。我遵循了dartlang.org上给出的建议。 出于这个原因，不编译原始的例子，使编辑器？有人有线索吗？ 你可以自己试试。 这是输出中显示的错误列表：

我找不到错误。一个想法？？？

我只是尝试了一下，没有任何错误和警告。 可能是您的包（依赖项）有问题。

---

您可以尝试

pub-get

和

pub-upgrade

（从

pubspec.yaml

上的上下文菜单）并在显示错误时发布输出
