android-studio – 未配置Dart SDK

我安装了Flutter并设置了 Android Studio.然后我在GitHub( https://github.com/flutter/flutter)上克隆了一个颤动的例子并在Android Studio中启动它,但它警告我“Dart SDK未配置”,这也发生在我的同事身上.但是,如果我在Android Studio中创建一个新项目,则完全没问题.

我做了什么:

>安装颤振
>安装Android Studio,以及包括Dart插件的Flutter插件
>在命令行中颤动运行正常,所有五个测试都通过了. (见下文)

上周,我可以通过命令行运行他们的示例(在该目录中),

flutter run

但现在我用Gradle显示了一些错误.

提前抱歉,我没有足够的声誉上传照片.

从git导入flutter项目后我遇到了同样的问题.这些是解决问题的步骤.

>文件 – >设置 – >语言&框架带>颤振
>选择flutter SDK路径:第一次安装颤振时,我们选择应安装颤振的位置.选择这个位置.
>单击确定,android工作室将刷新.如果问题得到解决,继续进行.
>如果您仍然遇到错误.
>转到this链接并安装Dart.
>在设置中转到相同的位置,..语言& Framework-> Dart并选择SDK位置.

这解决了我的问题.
