解决方法

在 Windows 上运行 Flutter 应用时遇到了 MSB3073 错误。这个错误通常与 NuGet 包的安装问题有关

错误信息表明 NuGet 无法成功安装所需的包，导致构建失败

1、使用vs打开项目
2、点击 工具 -> NuGet 包管理器 -> 程序包管理器设置

3、在常规中，将以下选项设置成图中所示

4、添加程序包源
https://www.nuget.org/api/v2/
名字可以随便取

5、点击确定，关闭vs

6、重新打开vs，工具 -> NuGet 包管理器 -> 程序包管理器设置 ，清除存储

7、删除图中框出的两项

8、运行命令

flutter pub get --no-example

flutter run -d windows

完结，撒花~
