在注册路由表时,Flutter提供了一个UnknownRoute属性,用来对未知的路由标识符进行统一的页面跳转处理,如下所示。 MaterialApp(…routes:{},onUnknownRoute:(RouteSettingssetting)=>MaterialPageRoute(builder:(context)=>UnknownPage()),//错误路由处理,返回UnknownPage);classUnknownPageextendsStatelessWidget{@overrideWidget...
多个路由,可以存在与同一个dart文件中的。 使用Navigator.pushNamed方法首先需要在 MaterialApp 中定义routes。 import'package:flutter/material.dart';voidmain(){runApp(newMaterialApp(title:'导航页面示例',home:newDemo()));}classDemoextendsStatelessWidget{@overrideWidgetbuild(BuildContext context){returnnewScaffol...
// main.dartMaterialApp(home:Tabs(),routes:{'/search':(context)=>SearchPage()},// 跳转页面设置按钮ElevatedButton(onPressed:(){Navigator.pushNamed(context,'/search',);},child:constText("命名路由跳转"))//“/search”这个链接的设置是要一致的 传值 // main.dartfinalroutes={'/search':(context...
…routes:{},onUnknownRoute: (RouteSettings setting) =>MaterialPageRoute(builder: (context) =>UnknownPage()),//错误路由处理,返回UnknownPage);classUnknownPageextendsStatelessWidget{@overrideWidgetbuild(BuildContext context) {returnScaffold(appBar:AppBar(title:Text('错误路由'), ), ); } } AI代码助...
routes: //注册路由 'first':(context)=>FirstPage(), 'second':(context)=>SecondPage(), , initialRoute: 'first', //初始路由页面 ); 在路由表中注册好页面后,然后就可以通过Navigator.pushNamed()方法来打开页面,如下所示。 Navigator.pushNamed(context,"second "); // second表示页面别名 ...
Navigator.popAndPushNamed(context,'/thirdPage'); 配置和使用命名路由示例代码 // ignore_for_file: prefer_const_constructorsimport'package:flutter/material.dart';voidmain() { runApp(MaterialApp( title:'Navigation with Named Routes',// 初始路由,应用启动时加载的路由initialRoute:'/',// 定义命名路由...
通过MaterialApp构造函数额外提供的属性:initialRoute和routes。 代码语言:javascript 复制 import'package:flutter/material.dart'import'package:navigation/FirstScreen.dart'import'package:navigation/SecondScreen.dart'voidmain(){runApp(MaterialApp(initialRoute:'/firstScreen',routes:{'/firstScreen':(context)=>First...
Push the route with the given name onto the navigator that most tightly encloses the given context, and then remove all the previous routes until thepredicatereturns true. Pop up Screen3 and Screen2, and then push the new Screen4.
routes:{// When navigating to the "/" route, build the FirstScreen widget.'/':(context)=>FirstScreen(),// When navigating to the "/second" route, build the SecondScreen widget.'/second':(context)=>SecondScreen(), }, ); To navigate to theSecondScreenpage, instead of using thepush()...
Widget build(BuildContext context) {returnMaterialApp(//home: Screen0(),initialRoute:'/',routes: {'/': (context) => Screen0(), '/first': (context) => Screen1(), '/second': (context) =>Screen2() },); } } To be noticed: 'home' & 'initialRoute' cannot be used at the same...
