描述需求

获取当前fragment的前一个fragment

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

请指教，感谢

Research direction
Examine the FragmentUtils.java file in the repository to understand existing methods for fragment stack management. Review the git history for any previous implementation of getPreFragment. Since the issue has an assignee, consider reaching out to them for details on the expected behavior. Check FragmentManager API for methods like getBackStackEntryAt() that could be used.
