【问题描述】：
开发人员第一次尝试设置环境。正在为其他开发人员设置相同的代码，没有任何问题。但只有在这台机器上，他才会遇到问题。
飞镖版本：2.7.2 Flutter 版本：1.12.13+hotfix.9
我们尝试进行 pub 缓存修复 但它没有帮助

【问题讨论】：
-
flutter doctor -v的输出是什么？在 Android Studio 4.0 版中，插件更改需要更新 Flutter 和 dart 插件。尝试检查更新。如果一切正常，请尝试flutter clean。 -
我在 Flushbar 上遇到了类似的问题，通过运行
flutter upgrade升级 Flutter，然后通过flutter clean清理项目。错误应该会消失。 -
@dev-aentgs 更新了颤振医生 -v 的输出
-
试过颤振升级和颤振清洁但得到同样的错误
