我刚把我的Macbook设置为扑动显影,

所以我下载了flutter SDK,并把它放在我的文档中。之后,我在命令行中设置了path变量来使用flutter。

我执行命令flutter create todolist,这样我就实现了一个空白项目。

我还用Dart-Code设置了我的visual studio代码,这样我就有了正确的语法高亮,智能感知等。

所以当我打开visual studio代码时,它会突出显示导入方法,如下图所示:

这意味着它还会突出显示正确的类,从而完全难以理解它是否是一个真正的错误。

我已经执行了pub get和flutter包get,并正确地得到了所有内容。 我的路径变量都是正确的。

为什么它突出显示它无法找到“导入”包?

确保运行此代码flutter pub add firebase_core

其他回答

重新启动visual studio代码对我有用!

去pubsec。在cupertino_icons后直接添加Yaml文件:

webview_flutter:

然后按右上角的Packages get,它就会很好地为你工作。

如果从终端执行:"Run flutter packages get"且错误继续,请检查是否所有包目录都列在'。包的文件。-有时你有包,但它没有配置在这个文件。

Warning! This package referenced a Flutter repository via the .packages file that is no longer available. The repository from which the 'flutter' tool is currently executing will be used instead. running Flutter tool: /opt/flutter previous reference : /Users/Shared/Library/flutter This can happen if you deleted or moved your copy of the Flutter repository, or if it was on a volume that is no longer mounted or has been mounted at a different location. Please check your system path to verify that you are running the expected version (run 'flutter --version' to see which flutter is on your path).

检查flutter包的输出可以发现,在我的案例中,原因是由于移动了flutter sdk。

删除。idea文件夹和。dart_tool后打开项目
