注册命名路由

class MyApp extends StatelessWidget {   
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),

      initialRoute: "home",   //默认启动页面
      //注册路由表
      routes: {
        "intentPage":(context) => IntentPage(),
        "home":(context) => MyHomePage(title: 'Flutter Demo Home Page'),
      },
    );
  }
}

跳转发送参数

class _TabBarPage2State extends State<TabBarPage2> {

  @override
  Widget build(BuildContext context) {

    return Center(
      child: Container(
        child: RaisedButton(
          child: Text('跳转传值'),
          onPressed: (){
            //第一个参数 命名路由的名字，第二个是要传输的数据
            Navigator.of(context).pushNamed("intentPage",arguments: nameBean("张三", 18));
            //nameBean 是自定义的一个数据实体类
          },
        ),
      ),
    );
  }
}


class nameBean{
  String name;
  int age;
  nameBean(this.name,this.age);
}

class _IntentPageState extends State<IntentPage> {
  nameBean name;
  @override
  Widget build(BuildContext context) {
    name=ModalRoute.of(context).settings.arguments;
    return Scaffold(
      appBar: AppBar(
        title: Text('传值页面'),
      ),
      body: Text('内容==${name.name}==${name.age}'),
