Flutter 更新后本地插件报错：Couldn't read file LocalFile: "***/***.kt" even though it exists!

先说一下报错Flutter版本：Stable channel v1.12.13+hotfix.5
报错问题同：

Running "flutter pub get" in push_plugin...                         0.2s
Running "flutter pub get" in example...                             0.3s
Couldn't read file LocalFile: '/Users/kamy/project_flutter/push_plugin/android/src/main/kotlin/com/bob/push/plugin/PushPlugin.kt' even though it exists. Please verify that this file has read permission and try again.

首先我的插件是java开发的，所以网上移动xxx.kt到kotlin文件中是行不通的。
官方Issue上也有人在提问，这是估计一个官方的bug，估计会在下一个版本解决（新语言总要经历这些）：

我的解决办法也很简单，那就是回退版本……回退到上一个版本v1.9.1+hotfix.6即可解决。
如果不想回退解决可以尝试用kotlin编写插件的***Plugin类来尝试是否可以解决。
