android - 找不到Flutter包路径

Question

我按照以下两个教程安装了Flutter，但未安装Android Studio:https://medium.com/@quicky316/install-flutter-sdk-on-windows-without-android-studio-102fdf567ce4和https://dev.to/ejgamer21/install-flutter-without-android-studio-58bi。
我已经将手机连接了USB调试功能，并运行了flutter doctor:一切似乎都很好(尽管我尚未配置IDE)。然后，我尝试使用hello_world目录中的flutter run运行Flutter附带的“Hello world”示例，但出现此错误:

lib/main.dart:5:8: Error: Error when reading '/C:/b/s/w/ir/k/archive/flutter/packages/flutter/lib/widgets.dart': Impossibile trovare il percorso specificato.
import 'package:flutter/widgets.dart';
       ^

          key: Key('title'),
               ^^^

(“不可能通过trovare il percorsospecificato”表示“找不到指定的路径”)
软件包的路径似乎出了问题，我在C:\Users\mpepi\Android\flutter\packages\flutter\lib处找到了所需的文件，该文件当然与第一行中的文件不同。我已经按照教程的说明设置了所有环境变量，我缺少了什么？

Answer 1

在.vscode文件中删除。重新启动Visual Studio代码的flutter应用程序并运行“Flutter run”。它为我工作。
