Description

官方的Example，发现在edit page执行change global state之后，主页面也执行了一次build。这个应该还可以理解。

但我发现，我把主页跳转到edit page的方法改成popAndPushName之后，也就是说在跳转之后，主页应该就不存在了，这时候change一下global state，主页仍然会执行一次build（view里面print会有打印，我理解就是build了一次）。

这个恐怕是一个bug。

Research direction
Investigate how fish redux's global state changes trigger widget rebuilds even when the page is removed from the navigation stack. Focus on the `build` method in view components and the state management integration. Check related code in the fish redux repository, particularly the `Store` and `Component` classes, and any existing discussions in issue #404 comments.
