我在Windows上安装了Flutter，并使用颤振医生检查了一切。我导入了Flutter插件。
现在，当我尝试通过Android Studio创建一个新的Flutter应用程序时，它永远不会结束。我得到了“创建Flutter项目”，就是这样。
消息区域包含“”C：\ Program Files \ Flutter \ flutter \ bin \ flutter.bat“--no-color create --template app --description”一个新的Flutter应用程序。“ - ororg anykey.co.il flutter_app4“它似乎停留在”建筑符号......“上。
我甚至把它留在了一夜之间，希望它能完成。
最后我必须杀了它。
编辑：似乎我的flutter.bat文件正在循环。我试过扑了一下医生（回声一下），这就是我得到的。最后一部分永远循环。

这很可能是因为你将Flutter放在Program Files中，这需要管理员权限才能写入其缓存文件。
我有一个PR Open应该会导致更友好的错误，但我建议将Flutter移动到非管理员用户可以写入的文件夹。
有同样的问题。
只需在管理员模式下运行Android Studio / IntelliJ即可。有用。
不久前我对同样的问题感到震惊。经过很多磕磕绊绊之后，我做对了。首先删除以前克隆的flutter文件并在用户文件夹中安装git。像C:\users\username\
克隆在你的git目录中扑动，设置路径C:\users\username\git\flutter\bin
现在使用命令flutter doctor如果你有android studio和intellij IDE，在它们中安装flutter插件，现在创建一个新项目。
你们都准备好了
我在MacOS 10.13.4上遇到了同样的问题，当在Android Studio（3.1）上创建一个新的Flutter项目时，IDE卡住了，在窗口底部显示了“建筑符号”这个短语。
在cli上运行命令flutter run时，消息是：startup lock。
然后我从颤动的sdk缓存中删除了锁：rm ./bin/cache/lockfile
我在Windows 10上遇到了同样的问题。确保“设置”中存在Flutter SDK的路径。设置>语言和设置>颤振> Flutter SDK路径
将计算机连接到互联网，然后尝试创建项目这将解决问题
