Dart SDK未配置

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。

IntelliJ IDEA ->首选项->语言和框架->颤振关于SDK部分设置路径到你的SDK，添加路径到flutter SDK windows版https://flutter.dev/docs/get-started/install/windows, macOS版https://flutter.dev/docs/get-started/install/macos和Linux版请参见此链接

操作系统：乌班图 19.04

IntelliJ: 1 . 2RC

我已经阅读了之前所有的答案，经过一段时间的尝试，我发现IntelliJ Flutter插件不需要Flutter的路径，而是需要基本安装文件夹。

所以这两个步骤:

安装IntelliJ Flutter插件: Ctrl + Shift + a(打开动作) 输入搜索'Flutter'，点击进入安装并重新启动IntelliJ 配置Flutter插件: Ctrl + Alt + s(打开设置) 输入搜索'Flutter'，在语言和框架下选择选项打开终端，颤振输出PATH_TO_FLUTTER/bin/flutter，你只需要PATH_TO_FLUTTER，所以从/bin中删除所有内容… 将位置粘贴到Flutter SDK路径输入并应用。

然后会要求您重新启动IntelliJ，您应该同时配置Flutter和Dart:

好运！

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。

上面的大多数选项已经展示了如何在Windows系统中配置Dart(如果你已经安装了Dart, Flutter Doctor显示一切正常)。

在MacOS上，此选项可在Android Studio > Preferences ('Command' + '，')下使用

在左侧窗格中找到Languages and Frameworks / Dart。勾选“启用Dart支持”并找到Dart SDK。它将在您的Flutter SDK安装目录'/ Flutter -安装-目录/ Flutter /bin/cache/dart-sdk'内。输入这个将自动填充下一行的dart版本，指出框架被选中。选中框启用Dart支持以下模块为您所需的项目。

单击Apply。单击Ok。

如上所述，这将解决大多数用例。如果错误仍然存在，可以执行“File > Invalidate Caches/Restart”。
