我有一个名为“clubview”的页面，位于 StatefulShellRoute 内。当用户位于此页面时，他可以导航到另一个名为“createClub”的页面。
我需要一种方法来随时显示 BottomNavigationBar，在这种情况下，我希望它在用户位于“clubview”中时显示，而不是在他们按下“createClub”时显示。如果我使用 GoNamed 我可以让它工作，但是我不能通过执行 pop() 返回。那么，有没有办法在使用pushNamed时仅在某些路线中显示BottomNavigationBar？
我的代码看起来部分像这样：
注意：我什至可以使“createClub”成为“clubview”的子路线，但即使如此我也无法使其工作。尝试在网络上搜索，但有关 StatefulShellRoute.indexStack 的资源非常有限

使用 go_router StatefulShellRoute.indexStack 根据路线显示和隐藏 BottomNavigationBar，同时还使用 Pushnamed 导航路线
为createClub路线添加_rootNavigatorKey
在仪表板屏幕中检查最上面的路线名称，
router.routerDelegate.currentConfiguration.last.matchedLocation将上面的名称与您要排除的路线名称相匹配，并有条件地显示/隐藏底部导航栏。
