android - 找不到 Flutter 包路径

问题描述

我按照以下两个教程安装了没有 Android Studio 的 Flutter：https ://medium.com/@quicky316/install-flutter-sdk-on-windows-without-android-studio-102fdf567ce4和https://dev.to/ ejgamer21/install-flutter-without-android-studio-58bi。我已经连接了启用 USB 调试的手机并且我已经运行flutter doctor：一切似乎都很好（尽管我还没有配置 IDE）。然后我尝试flutter run在hello_world目录中运行 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';
       ^
lib/main.dart:12:16: Error: Method not found: 'Key'.
          key: Key('title'),
               ^^^

          textDirection: TextDirection.ltr

          ^^^^^^

  runApp(

（“Impossibile trovare il percorso specificato”的意思是“找不到指定的路径”）包的路径似乎有问题，我找到了所需的文件，C:\Users\mpepi\Android\flutter\packages\flutter\lib该文件当然与第一行中的文件不同. 我已经按照教程解释设置了所有环境变量，我缺少什么？

解决方案

在 .vscode 文件中删除。重新启动 Visual Studio 代码的颤振应用程序并运行“颤振运行”。它对我有用。
