Dart 更改为设备模式时出错，已关联省道类型

我有一个dart聚合物项目在dartium很好地工作。当切换到设备模式/响应设计模式时，它会抛出第一种类型的多个错误，我已删除了其中一些错误：

环境：
sdk:'>=1.0.0=0.11.3我还查看了的ISSUE跟踪器，您应该不再需要依赖项覆盖。如果你在Chrome（而不是Dartium）中也出现了错误，那也会很有趣@GünterZöchbauer谢谢，我试图删除依赖项覆盖，结果是polymer更新到rc.3，polymer_互操作更新到rc.2，但Dartium中仍然存在错误，但是不要在chromium中使用它们。我已经创建了一个bug报告，我还查看了ISSUE跟踪程序，您应该不再需要依赖项覆盖。如果你在Chrome（而不是Dartium）中也出现了错误，那也会很有趣@GünterZöchbauer谢谢，我试图删除依赖项覆盖，结果是polymer更新到rc.3，polymer_互操作更新到rc.2，但Dartium中仍然存在错误，但是不要把它们放在铬里。我已经创建了一个bug报告
