简单的Navigator.push

• 参考：https://flutter.dev/docs/cookbook/navigation/navigation-basics

假设我们app长这个样子

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        primarySwatch: Colors.blue,
      ),
      // demo app 一般都直接用home来指定初始页面，当然也可以使用NamedRoute
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

• push like this:

RaisedButton(
              child: Text('open ListPage'),
              onPressed: () {
                Navigator.push(context, MaterialPageRoute(
                    builder: (context) => ListPage()
                ));
              },
),

• pop like this:

Scaffold(
      appBar: AppBar(title: Text('ListPage'),),
      body: Center(
        child: RaisedButton(
          child: Text('back'),
          onPressed: () {
            Navigator.pop(context);
          },
        ),
      ),
    );

Navigate with named routes

• 参考：https://flutter.dev/docs/cookbook/navigation/named-routes

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        primarySwatch: Colors.blue,
      ),
      // home: MyHomePage(title: 'Flutter Demo Home Page'),
      initialRoute: '/',
      routes: {
        '/': (context) => MyHomePage(title: 'Flutter Demo Home Page'),
        '/ListPage': (context) => ListPage(),
        '/DetailPage': (context) => DetailPage(),//敲出来之后，会自动添加import，不需要手动import
      },
    );
  }
}

• Navigator.pushNamed

RaisedButton(
          child: Text('open detail page'),
          onPressed: () {
            Navigator.pushNamed(context, '/DetailPage');
          },
        ),

• pop和之前还是一样的。

传递参数
