Flutter/画面遷移

その1

routerをMyAppの中に追加

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
      routes: <String, WidgetBuilder> {
        '/help': (BuildContext context) => new MyHomePage(title: 'page help'),
        '/privacy': (BuildContext context) => new MyHomePage(title: 'page privacy'),
        '/use': (BuildContext context) => new MyHomePage(title: 'page use'),
      },
    );
  }
}

画面遷移

Navigator.of(context).pushNamed('/use');

    settings: const RouteSettings(name: "/use"),
