Dart 及 flutter 初體驗
- 先在入口處設定路由
MaterialApp(
// home: HomePage(),
initialRoute: '/',
routes: {
'/': (BuildContext context) => HomePage(),
'/Page2': (BuildContext context) => Page2(),
},
),
- 使用路由
GestureDetector(
onTap: () {
NavigatorState nav = Navigator.of(context);
nav.pushNamed('/Page2');
},
child: buildImageView(urls[index], align: positions[index]),
);
- 按回上頁按鈕要能回到原本頁面：
return Scaffold(
appBar: AppBar(
leading: BackButton(
onPressed: () {
Navigator.of(context).pop('來自 Page2');
},
),
),
);
