Description
flutter入门，对项目里的悬浮按钮组件OverlayToolWrapper很感兴趣，但是有一个疑惑，就是在初级路由页面的时候移动悬浮按钮会有一个靠边的动画，调用_ctrl.forward()之后_listenAnimate回调方法能正常执行，但是为什么进入子路由页面调用_ctrl.forward()之后_listenAnimate回调方法只执行了一次，所以靠边的动画消失了。

Research direction
Read the OverlayToolWrapper implementation and trace _ctrl.forward() and the _listenAnimate callback on both the initial route and a child route. Reproduce the differing callback behavior, then document the cause and verify that the edge-snapping animation behaves consistently across those routes.
