flutter pub add route_observer_mixin基于插件公开信息、社区数据与项目使用情况整理的选型参考。
RouteObserveMixin 是一个 Flutter 工具混入，可简化处理路由生命周期事件（如 didPush、didPop、didPushNext 和 didPopNext）。它使小部件能够响应导航变化，而无需手动管理路由或使用全局观察器。适用于与导航流程相关的状态管理和 UI 更新，在跨多个平台的复杂路由场景中，可简化交互。
以下为关联源码仓库的 README 原文快照，最新内容请访问源码仓库。
RouteObserveMixin provides easy access to didPush/didPop/didPushNext/didPopNext.

// Of course, this is also ok.
// I demonstrated that [MultiProvider] can be used for RouteObserverProvider👍
