Description

一个主Activity 底部多个Fragment 我想只要在这几个底部的Fragment内 做退出事件 意思就是 在这几个底部内的Fragment 2秒内重复按返回键 都能退出App onRiggerBackPressed 这里面怎么写？ 我测试了一下，如果底部的Fragment 都去onRiggerBackPressed 进行载拦判断2秒退出事件，并不能退出，

Research direction
Investigate the FragmentRigger library's AOP based fragment management and its onRiggerBackPressed method. Review the 6 comments on the issue for any proposed solutions or maintainer input. Look at the library's documentation and examples to understand how back press handling is intended to work. The user wants to implement a double press to exit behavior in bottom fragments, which may require custom event interception or coordination between fragments. Consider if the library already supports this or if a new feature is needed.
