Flutter之多页面路由跳转控制

首先在main.dart中添加如下代码

Map<String,WidgetBuilder> datas = {
 '/pageone':(builder){
   return PageOne('数据1');
  },
  '/pagetwo':(builder){
    return PageTwo('数据2');
  }


};

然后再下面添加路由的管理

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
//  @overrider
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
