Dart 为什么WebComponents声称我有一个；“非法字符”；在我的道路上？

运行

pub-service

后，我收到一条异常错误消息：

有人能理解这一点吗？

看起来很像。你能检查一下你使用的分析仪版本吗？@GünterZöchbauer我看到了那篇帖子，并且已经将我的

analyzer

软件包版本控制降低到

analyzer软件包移动速度非常快，因此依赖于
analyzer
的软件包的版本限制非常狭窄，因为每次analyzer更新都可能包含破坏性的更改。不经常更新或不太注意支持所有内容的最新版本的包会下拉具有共享依赖性的所有直接依赖项和可传递依赖项的版本。这就是为什么通常需要相当长的时间才能获得所有内容的最新版本。如果你不发布到pub，你可以尝试使用
dependency\u overrides
@GünterZöchbauer强制更新analyzer版本。好的，谢谢你的建议。
