Android Studio中Flutter Module文件索引失败问题求助

我用VS Code开发Flutter有段时间了，现在想切换到Android Studio。我的项目是嵌入Android应用的Flutter Module，这个方案已经稳定运行好几年了。

把项目导入Android Studio后，所有文件因为没被索引都显示黄色。

尝试运行项目时，配置界面底部出现如下错误：

如果创建新Flutter项目然后粘贴所有文件，项目能正常运行，但重启IDE或者执行Invalidate Cache后问题又会出现。我不清楚原因，怀疑是有内容覆盖设置导致索引丢失。

已尝试的解决方法 #

我试过网上能找到的所有办法：

• Invalidate Cache
• 保留并粘贴.iml文件到项目中
• 删除.idea文件夹和.iml文件
• 使用Android Studio内置工具修复项目
• 重新创建项目并粘贴所有文件（仅在重启IDE前有效）

更新！ #

我尝试创建空白新项目，逐个添加文件并重启IDE，定位导致索引失败的文件。最终发现问题出在build.gradle.kts及相关Gradle配置上，推测Android Studio因为Gradle配置出现异常。请问现在该怎么解决？

以下是去除隐私信息后的build.gradle.kts文件：
