How are route positions handled in BottomNavigation?

Hello, has anyone had the same problem using BottomNavigation with Firebase dynamically? When I delete only the last route on the right I get this error. If I am on another route and I delete the last route on the right, nothing happens, apparently it is a problem in the array of routes but I don't understand.

从 BottomNavigation 的路由处理开始，复现删除最右侧 Firebase 驱动路由的情况，分别测试当前位于该路由和位于另一条路由时的场景。记录缺失的错误详情和预期行为；一旦能够复现这些情况并确立明确的完成条件，该 issue 就可以开始处理。
