【问题描述】：
我正在尝试包含条带插件，当我在 pubsec.yml 中添加时，在文件中导入出现错误时没有任何反应...我创建了一个新项目并导入插件，但同样的事情发生在其他插件工作文件中。

它导入但仍然给出插件丢失错误：

【问题讨论】：
-
我偶尔会遇到这种情况是 Visual Studio 代码与其他包。确保您已全部保存，然后手动键入导入。出于某种原因，当我剪切和粘贴时，它有时会忽略导入。不知道为什么。
-
也尝试在终端中运行
flutter packages get，看看它是否会给你错误。 -
当我尝试手动导入但仍然出现缺少插件错误。同时感谢您的建议。
-
我正在编辑我的问题，但出现错误请查看上面的消息。
-
这可能看起来微不足道，但只是为了确保，您是否尝试过关闭项目并重新打开？
