I have been studying GetX's Nav2 for some time. You should use `GetRouterOutlet.pickPages` or `filterPages` to customize which GetPages should be placed in the current navigation stack.

However, in your example, you only need to remove the `participatesInRootNavigator ` option from the settings page.

Now you can refer to my sample code, which has implemented page state preservation. https://github.com/hightman/getx5-example_nav2

从你的描述看应该是这个应用场景导致了这样的结果，我建议你采用限制 import 进程数据的办法，待其它进程退出后其它 project 再唤起 import.

刚看了下代码，本身默认限制 5个 import 进程呀？你们是自己改大了吗。
