For those who are having a problem with the declaration of FullLifeCycle, just change the name of the class to FullLifeCycleMixin.

Sorry, I had tried to use ur code to run, but the lifecycle function was not called any.

Same here - sort of. Things like didPopRoute or didPushRoute are not called; onPaused, onResumed etc. seem to work.

这里也一样-有点。不调用 didPopRoute 或 didPushRoute 之类的东西；onPaused、onResumed 等似乎有效。

mine too

不好使

p.s. this is for the app lifecycle, not for the widget lifecycle. Just point it out in case someone thought this is for widget lifecycle recording
