【问题描述】：

我的项目中出现此错误。我什至创建了一个新的普通颤振项目，但我也遇到了同样的错误。

我什至尝试清除 flutter.pub-cache\hosted\pub.dartlang.org\cupertino_icons -****。我什至尝试专门给出版本名称。但它仍然无法工作在 abccdddd 中运行“flutter pub get”... 1.0s 在调试模式下在 SM J600G 上启动 lib\main.dart... 正在运行 Gradle 任务 'assembleDebug'...

你应该重新安装flutter

【参考方案1】：

我打开了 .pub-cache/hosted/pub.dartlang.org/cupertino_icons-0.1.3/lib/placeholder.txt 文件并清除了它。它开始为我工作。真的很奇怪，但确实如此。
