如果我在终端运行 flutter config，终端会抛出flutter command not found异常

Answer 1

这是试图找到 gradle 的代码： https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/android/gradle.dart#L37

flutter命令位于您下载的flutter SDK的bin目录中。我们的设置文档中介绍了将其添加到您的路径中：https://flutter.io/setup/#get-the-flutter-sdk

您可以使用命令的参数或全局使用带有 --gradle-dir 或 --android-studio-dir 标志的 flutter config 来指定 gradle 二进制文件的位置。

正如您在链接代码中看到的，我们知道如何在某些默认位置找到 gradle，例如在 /Applications/Android Studio.app 内部或通过读取您的路径变量。我们可能可以添加更多默认位置。

如果您认为您的 Android SDK 安装在我们没有检查的默认位置，请在 https://github.com/flutter/flutter/issues/new 提交错误，我们很乐意修复。
