Flutter 换屏回调

Question

I want to get a callback when the screen is changed, so I can stop my recurring request that runs on that specific screen. “dispose” is only called when Navigator.pop is used, but not when Navigator.push is called. Is there a way to detect that the screen is changed and not being shown at the moment?
