Android 14下awesome_notifications本地定时通知延迟问题求助

所有通过awesome_notifications设置的本地定时通知均存在不定时长延迟，短则30秒，长则1分钟，偶尔甚至会出现5-7分钟的延迟。已关闭应用电池优化，该问题在debug/release模式、应用前后台状态下均会出现，期望通知能在指定时间精准触发。

实现情况 #

使用awesome_notifications实现通知服务，通过日期时间选择器让用户设置截止时间，调用NotificationCalendar.fromDate()调度通知。已确保应用初始化时请求通知权限，dueDate配置正确、权限已授予，且包配置符合文档要求。控制台无错误/异常输出，但通知始终无法按时触发，延迟时长在30秒至1分半浮动。此前相关问题多为通知完全失效，未找到针对延迟问题的解决方案。

提供了最小可复现示例仓库，可克隆后在Android Studio中于Android 14物理设备上运行debug和release模式测试。
