java - 无法转换 flutter.jar 以匹配属性

Question

我在运行 flutter 应用程序时遇到问题。

我尝试解决问题的方法。

1. 我已经重新安装了 Flutter。
2. 删除了 Users/MyUserName/.gradle/cahce 中的 gradle 缓存
3. 删除了 Users/MyUserName/.gradle 中的整个 .gradle 文件夹
4. 重新安装了 Gradle。
5. 在没有/build 文件夹的情况下从 repo 再次克隆项目。
6. 跑得干干净净。
7. 运行 gradle clean。
8. 卸载 gradle 并降级到 5.6.4
9. 尝试了来自具有类似问题的用户的 stackoverflow 的各种解决方案。
10. 重新安装 Android Studio

我的环境变量和 gradle 都不稳定，并且 100% 正常工作。

使用我得到的堆栈跟踪运行我的汇编:
