Answer 1

我决定降级stagehand，我使用了以下命令：

$ pub downgrade stagehand 3.3.1

Answer 2

在VSC终端中使用命令后：

false

我收到此错误：

  

$：术语'$'不被识别为cmdlet，函数，   脚本文件或可操作程序。检查名称的拼写，或者   如果包含路径，请确认路径正确，然后重试。

     

在第1行：char：1   + $ pub降级stagehand 3.3.1   +〜       + CategoryInfo：ObjectNotFound：（$：String）[]，CommandNotFoundException       + FullyQualifiedErrorId：CommandNotFoundException

Answer 3

已解决。 修复：将Flutter SDK更新到v1.7.8 + hotfix.2-stable。
