Description

描述需求

获取当前fragment的前一个fragment

可借鉴的

FragmentUtils.getPreFragment

获取目标fragment的前一个fragment 之前版本有这个方法，现在怎么没呢？我使用以下方法都无法获取到栈内fragment的集合

getFragments : 获取同级别的 fragment getFragmentsInStack : 获取同级别栈中的 fragment getAllFragments : 获取所有 fragment getAllFragmentsInStack: 获取栈中所有 fragment

请指教，感谢

Contributor guide

Research direction
Implement a method `getPreFragment` in FragmentUtils that retrieves the previous fragment from the back stack. Refer to the existing methods like `getFragments`, `getFragmentsInStack`, etc., and use FragmentManager's back stack entries to find the previous fragment.
