【问题讨论】：

添加你实现的代码

标签： android flutter

【解决方案1】：

此软件包不再维护且已过时。它是为早期的 Flutter 开发的，不使用 Dart 2。Readme 中还说：

此项目教程已过期。它是用非常早期的 Flutter 版本创建的，我无法维护它

Here 是一个描述您的问题的问题。

【讨论】：

非常感谢您的回答。我可以确切地知道哪些行或语法已经过时了吗？

【解决方案2】：

似乎这个问题与 /build 目录有关。运行：

flutter clean //removes your /build directory
flutter run

如 this issue 中所述
