Flutter 更新後本地插件報錯：Couldn't read file LocalFile: "***/***.kt" even though it exists!

先說一下報錯Flutter版本：Stable channel v1.12.13+hotfix.5
報錯問題同：

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開發的，所以網上移動xxx.kt到kotlin文件中是行不通的。
官方Issue上也有人在提問，這是估計一個官方的bug，估計會在下一個版本解決（新語言總要經歷這些）：

我的解決辦法也很簡單，那就是回退版本……回退到上一個版本v1.9.1+hotfix.6即可解決。
如果不想回退解決可以嘗試用kotlin編寫插件的***Plugin類來嘗試是否可以解決。
