lifecycle_lite #

通过简单几步,就可以让你使用whenShow()/whenHide()方法来监听页面的生命周期(退回到了该页面/打开其他页面挡着了该页面)了

Principle #

这个库的实现很简单,你完全可以通过阅读代码后自己扩展实现。主要就是在MaterialApp中添加一个对路由的监听,也就是MaterialApp#navigatorObservers,之后通过对路由的监听来记录一个路由的栈。再在对应的State#initState方法或StatelessWidget#createElement中绑定两个生命周期方法的实现到最上层路由。 这样在每次监听到路由变化时,去调用顶层路由对应的绑定方法就OK了。 记得在路由被移出的时候对应的方法也要移出哦~

Getting Started #

import 'package:lifecycle/lifecycle_mixin.dart';

1.首先在你的根布局MaterialApp中绑定一个路由监听LifeNavigatorObserver().

    MaterialApp(
        navigatorObservers: [
            LifeNavigatorObserver(),
        ],
    );

2.在你需要添加监听的State中混入LifecycleMixin,并在initState中调用bindImplIntoRoute()方法。

2.StatefulWidget的话,需要混入LifecycleStatefulMixin,对应的StatelessWidget,使用的是LifecycleStatelessMixin

3.实现whenShow()/whenHide()方法,代码看起来是下面的样子。

///Statefule page
class WorksDetailState extends State with LifecycleStatefulMixin{

    @override
    whenShow() {
        super.whenShow();
        print("LifeNavigatorObserver---Show了");
    }

    @override
    whenHide() {
        super.whenHide();
        print("LifeNavigatorObserver---Hide了");
    }
}
///Stateless page
class StatelessPage extends StatelessWidget with LifecycleStatelessMixin{

    @override
    whenShow() {
        super.whenShow();
        print("LifeNavigatorObserver---Show了");
    }

    @override
    whenHide() {
        super.whenHide();
        print("LifeNavigatorObserver---Hide了");
    }
}

尽情享用吧 :P;
