程序启动主函数文件

 import 'package:flutter/material.dart'; import 'package:ichat/routers/route_config.dart';   main(){     runApp(       MaterialApp(         title: "dynamic router",         debugShowCheckedModeBanner: false,         theme: ThemeData(primarySwatch: Colors.blue),         // home: const StaticRouterPage(), //home和 initialRoute不能同时存在，否则会报错         initialRoute: RouteConfig.initRoute,         routes: RouteConfig.routes,         onGenerateRoute: RouteConfig.onGenerateRoute,       )   );   }

路由使用的几种方式

1、push不带参数

Navigator.of(context).push(MaterialPageRoute(                                     builder: (context) => const PersonPage(),                                   ));

2、push带参数

Navigator.of(context)          .push(MaterialPageRoute(builder: (context) => const NewsPage(title: "国际小新闻",newsId: 20),                                   ));

3、通过命名路由配置pushNamed

Navigator.of(context).pushNamed("/search");

4、 通过命名路由配置带参数pushNamed

Navigator.of(context).pushNamed("/form",arguments: {   "key1":"value1",   "key2":"value2", });

5、路由返回

Navigator.of(context).pop()

6、pushReplacementNamed

Navigator.of(context).pushReplacementNamed("/search");
