在IntelliJ中，Dart文件的Alt+Enter功能失效了。

Question

在IntelliJ中，Dart文件的Alt+Enter功能失效了。

24

在构建Flutter应用程序时，ALT + Enter键盘快捷键非常方便，不仅可以带出快速修复选项，还可以带出弹出菜单以包装/删除小部件。它一直工作得很好，直到我运行了flutter upgrade并更新了IntelliJ中的Dart和Flutter插件（版本2018.3.5）。

我已经尝试了一个小时的键盘快捷键设置，禁用和重新启用Dart / Flutter插件，在IntelliJ中重启和无效化缓存，关闭所有其他应用程序并多次重新启动Windows 10。但是没有任何作用。我现在无法再使用Alt+Enter了。在我更新插件和Flutter SDK之前，它一直很好用，因此似乎是这些更新中的某些内容破坏了它。

实际上，Alt+Enter似乎已经无法正常工作了，而且“建议气泡”也不会出现。例如，如果我输入

String x  = 2;

数字2会得到正常的红色下划线，但没有提示灯亮起，按下Al+Enter也没有任何反应。我已经三次确认在设置中选中了“显示意图提示灯”，并且分配了正确的键盘快捷键（为确保无误，我已将其重置为默认值）。

最近还有人遇到过这种情况并找到了解决方法吗？我尝试了在StackOverflow上找到的所有建议，但它们都不起作用，也没有一项专门针对Dart/Flutter意图/操作/快速修复弹出窗口。

编辑

这是重新启动后的IntelliJ日志。我起初使用了似乎会破坏Alt+Enter的Dart SDK，然后切换到另一个使Alt+Enter工作但禁用了选择运行应用程序的设备的SDK，最后又切换回第一个（请参见日志末尾附近的注释）：

删除 ~/.dartServer/.analysis-driver/ 或许值得一试。 - Günter Zöchbauer

请确认一下，文件类型关联是否仍然正确？因为意图是基于上下文/类型的... - BitfulByte

我尝试删除了 .analysis-driver 文件夹，但似乎没有任何效果。然而，我注意到在 IntelliJ 的 Languages and frameworks -> Dart 设置中，Dart SDK 被设置为 C:\Users\MyUsername\flutter\bin\cache\dart-sdk（版本为 2.2.0-edge.xxxxxxxxxxx）。下拉菜单中还有另一个 SDK，C:\Program Files\Dart\dart-sdk（版本为 2.1.0）。当我选择了 2.1.0 SDK 后，一切立即恢复正常。不确定该设置是如何更改的，是否之前就是这样，或者是更新导致的。 - Magnus

在重新启动IDE并重现问题后，是否可以共享idea.log（“帮助|显示日志”）？ - y.bedrov

@y.bedrov，请查看我的编辑。 - Magnus

前往 文件 > 设置 > 编辑器 > 意图，然后确认 Dart分析服务器。

对于Mac OS：
前往Android Studio -> 首选项 -> 编辑器 -> 意图 -> 由Dart分析服务器提供的快速协助（标记它）-> 应用。

已经检查过了，但是Alt+Enter仍然没有建议导入库。 - Davoud Badamchi

这种情况有时也会发生在我身上，大多数情况下只是IDE中的一个错误，请尝试重新启动您的电脑以激活此错误。感谢您，希望您能解决它！ - Felipe Sales

尝试清除缓存并重新启动

- Henok

谢谢，它起作用了！只是为了澄清，此选项在文件->无效缓存/重启中。 - Chuy47

清除缓存/重启，解决IntelliJ问题的90%。 - rgv

从Flutter 2降级到Flutter 1.22.6后，我遇到了同样的问题，但是“使无效并重新启动”帮助恢复了建议。 - Volodymyr Buberenko

这对我来说是工作，谢谢。 - Somwang Souksavatd

我曾经遇到过相同的问题，这个方法对我有用：

切换到不同的flutter channel。如果你正在使用stable，请切换至beta或反之。切换channel的操作指南可以在这个链接中找到：https://flutter.dev/docs/development/tools/sdk/upgrading
运行flutter upgrade。
重启你的IDE。
检查灯泡（或ALT-Enter或Option-Return）是否已激活。
切换回你的其他channel，然后重复以上步骤2和3。

当我导入了另一个Flutter项目时，我注意到在那个项目中Alt+Enter键可以正常使用，但在原始项目中仍然无法使用。我尝试删除所有与IntelliJ相关的文件（特别是*.iml和.idea），重新创建原始项目 - 但Alt+Enter仍然无法使用。

这时，我开始仔细查看lib源文件夹中的文件，并发现了一个我之前没有注意到的可疑文件，名为analysis_options.yaml。它包含了：

analyzer:
    language:
        enableSuperMixins: true

我删除了它（以及与IntelliJ相关的*.iml文件和.idea文件夹），并重新创建了项目 - 最终Alt+Enter再次正常工作！
看起来同事很久以前添加了analysis_options.yaml文件，所以我仍然不确定为什么这个问题直到在项目上工作几个月后才出现。

- Magnus

甚至更奇怪的是，在我的情况下，该文件的内容被注释掉了，所以它们并没有被使用。这可能是某个 bug。如果仅删除文件无法解决问题，请记得重新启动 Android Studio。 - vovahost

如果你仍然遇到这个问题。

尝试禁用所有插件并检查是否开始工作。
如果它开始工作了
逐一启用插件以检查导致问题的插件。

针对Mac用户且无法解决问题的情况，可以尝试如下方法：

。同时，请确保“Quick assist...”已勾选（参见@Gazihan Alankus的回答），并安装了Dart和Flutter插件于您的Android Studio中。

如果以上解决方案无效，请删除项目的.idea文件夹。

检查键盘映射中“显示意图操作”的快捷方式是否为“Alt+Enter”。在我的情况下，我使用的是Mac OS X、Android Studio和Eclipse Mac OS X键盘映射，而“显示意图操作”的快捷方式是“command+1”。

就是这个。不客气。

- Gazihan Alankus

不，这并没有帮助。至少在我的IntelliJ安装中，如果我提到的analysis_options.yaml文件存在，ALT+Enter就停止工作了。这个设置在这种情况下没有帮助。不用客气 ;) - Magnus

很好，但是许多其他人来到这篇文章并没有被警告我提到的那一点。所以，我认为downvote是不必要的。https://github.com/flutter/flutter-intellij/issues/2448#issuecomment-401527661 - Gazihan Alankus
