失败：配置项目“：path_provider”时出现问题

Question

命令没有错误flutter doctor -v。

我尝试删除该path_provider_macos目录，但没有成功。

我更新了gradle插件，但还是不行。

我在 vscode 和 android studio 中都遇到了这个错误。我删除并安装了几次flutter sdk，还是不行。

当我将 gradle 版本更改为 3.3.0 时，出现了不同的错误。它也不起作用。

Answer 1

您是否在 android 清单中添加了读/写外部存储的权限。

如果没有，则需要 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 在 android 清单文件中添加。

您还需要在调用之前获得运行时权限getExternalStorageDirectory();，您可以使用名为permission_handler的包
