这是尝试查找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https://flutter.io/setup/#get-the-flutter-sdk

中介绍了如何将其添加到您的路径中

您可以使用args为命令指定gradle二进制文件的位置，也可以使用带有flutter config或--gradle-dir标记的--android-studio-dir全局指定。

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（例如内部/Applications/Android Studio.app）或通过读取路径变量来查找gradle。我们可能会添加更多默认位置。

如果您认为我的Android SDK安装在默认位置，我们不会检查，请在https://github.com/flutter/flutter/issues/new提交错误，我们很乐意解决。
