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flutter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。但如果我在Android Studio中创建一个新项目,就完全没有问题。

我所做的:

安装了颤振 安装了Android Studio,以及Flutter插件,包括Dart插件 在命令行中颤振运行正常,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例子(在那个目录下),

flutter run 

但现在我显示一些错误与Gradle。

我解决了,试试:

点击打开SDK设置,打开Flutter,然后在下载时添加SDK位置。

我有同样的Dart SDK问题,我使用这个解决方案。为了解决这个问题,而不必每次都使用终端来测试我的程序,我遵循的步骤如下。

Find flutter SDK path. I did so by typing in echo $PATH and finding the path with /flutter/bin. Assuming your path is something like .../flutter/bin just add on /cache/dart-sdk/bin making it .../flutter/bin/cache/dart-sdk/bin. This .../flutter/bin/cache/dart-sdk/bin is the location of your Dart SDK. Assuming you say the same Dart SDK is not configured error accompanied by something where you can configure your Dart SDK. You click the configure option and set .../flutter/bin/cache/dart-sdk as your SDK. That should fix your problem. If not head over to the next step. Open your Android Studio preferences(Command + ',') and go to Languages and Frameworks>Dart. Under the Dart menu, you should be able to enter your Dart SDK path.

我使用IntelliJ IDEA完成了这些步骤,所以它们应该是差不多的。如果这不起作用,有时做一个虚拟的Dart项目可以让事情重新工作。这为我解决了一个类似的问题。

颤振通常安装(按插图)在。

C:\src\Flutter

对于Windows安装…

您可以尝试运行flutter doctor来解决安装问题。 还要运行flutter升级以获得最新版本的flutter和Dart sdk。

DART SDK可以在

/flutter/bin/cache/dart-sdk

我按照以下步骤来解决这个问题:

首先,转到:文件->设置->语言和框架->颤振

在“flutter SDK path”下面,输入您安装flutter的位置 我的是:C:\src\flutter

点击应用,然后确定,android工作室将刷新。 问题会解决的。

对于Mac,

点击Android Studio, 然后点击Preferences… 在DART SDK Path中设置您的路径。

启用此为您的项目(像图像显示),然后应用

安装Flutter后,安装Dart sdk的最佳方式是创建一个新项目。在此窗口中,单击“安装SDK”。这将安装正常工作所需的所有内容。
