我刚刚建立了一个flutter web项目。我在github页面上托管了它。在成功地从创建存储库到部署项目之后，我得到了下面的错误...
(index):46 Uncaught ReferenceError: _flutter is not defined我不明白为什么会这样。我试过flutter clean。
我搜索了解决方案。但许多人建议运行flutter clean命令，但它对项目没有影响。
这里是我的代码代码的网页建设.

Uncaught ReferenceError: _flutter is not defined可能是由错误的部署文件夹引起的。你必须delpoy
web目录而不是build/web以下是github Issues中一些引用：https://github.com/flutter/flutter/issues/107448#issuecomment-1181591460
或者您可以尝试此解决方案：

Flutter build websupposed to output a file called flutter.js? Because it does not by me :(
