【问题描述】：
我使用 Android Studio 作为编写 Flutter 的 IDE。在此之前我能够创建 2 个项目，而且效果非常好。我不得不从 Github 克隆一个 repo。 IDE 说要获取配置。我这样做了，然后就发生了。
我已经安装了sdk。
Flutter Doctor 结果：

【问题讨论】：

我之前也遇到过类似的问题，并通过创建一个新项目并将这些 lib 文件从 Github 复制到我项目的 lib 文件中来修复它。我之前在 Github 中克隆的问题是我推送到 Github 的计算机上的设置被复制了。这会导致问题，因为不同计算机的设置不同。
-
是的，试过了。但它我的手机也没有出现在那里。我在以前的项目中也尝试过。
-
这听起来可能很愚蠢，但每当我遇到这些意想不到的问题时，我都会先尝试重新启动环境。在这种情况下，我只是在加载新项目后重新启动了 Android Studio，然后错误就消失了。
