而CustomNavigatorObserver或者回调函数中的参数Route都能直接获取到NavigatorState,到这里,我们不通过context而直接获取到了控制导航的NavigatorState。 现在,我们就可以写两个方法来控制前进和返回。 返回,调用navigator的pop()。 voidback(){if(canBack()){finalcurrent=_actions[_currentIndex];_currentIndex-=1;if(cu...
MaterialApp和CupertinoApp已经在其引擎中使用了一个Navigator. 你可以通过Navigator.of()访问navigator 或者 使用Navigator.push()显示一个新屏幕, 并且可以通过Navigator.pop()返回上一个屏幕: import 'package:flutter/material.dart'; void main() { runApp(Nav2App()); } class Nav2App extends StatelessWidget ...

那么问题来了,这个 Context 到底如何设置的呢? 答案是通过 Catcher 中可选参数navigatorKey 其中流程比较简单可以自行查看源码。 如果用户设置了 DialogReportMode 之后,呈现出来的就是上面效果,用户点击 Cancel 就没后文了,点击 Accept 就会继续把当前 Report 流传下去。
