Navigation 导航深度嵌套的路由时会产生错误-“包：angular/core/scope.dart”：断言失败“isAttached”不正确（angulardart 0.9.10）

当我从最深的视图导航到下一个父视图时，我收到以下错误消息：“package:angular/core/scope.dart”：失败的断言：第297行位置12：“isAttached”不正确

上面的错误是什么意思？我的路由器定义有错误吗？是否可能是在深度嵌套视图中放置的

如何再现这种错误情况：

向下导航到最深的路线，即一直导航到其中一个子视图，如屏幕截图-1所示[https://onedrive.live.com/embed?cid=CCCEB2154F3BF15A&resid=CCCEB2154F3BF15A！869&authkey=AJQ-1hF_KUVNsYM]

现在，尝试导航到View2，即下一个父视图，如屏幕截图2所示[https://onedrive.live.com/embed?cid=CCCEB2154F3BF15A&resid=CCCEB2154F3BF15A！868&authkey=AEZyo3s7A-el880]

上述两个步骤应产生以下错误转储：

'package:angular/core/scope.dart': Failed assertion: line 297 pos 12: 'isAttached' is not true.
