1 匿名方式 實(shí)現(xiàn)頁(yè)面跳轉(zhuǎn)與返回

1.1 跳轉(zhuǎn)下一頁(yè)

Android風(fēng)格

Navigator.push(
  context,
  MaterialPageRoute(builder: (context) => const Page1()),
);

iOS風(fēng)格

Navigator.push(
  context,
  CupertinoPageRoute(builder: (context) => const Page1()),
);

從下到上彈出頁(yè)面

Navigator.push(
   context,
   MaterialPageRoute(
     builder: (context) => const Page1(),
     // 全屏彈窗效果，從下往上出現(xiàn)
     fullscreenDialog: true,
   ),
 );

1.2 返回上一頁(yè)

Navigator.of(context).pop()

1.3 傳參跳轉(zhuǎn)下一頁(yè)并獲取返回值

傳參跳轉(zhuǎn)下一頁(yè)，并獲取返回值

final result = await Navigator.push(
  context,
  MaterialPageRoute(
    builder: (context) => const Page1(param: 'param'),
  ),
);
print(result);

攜帶參數(shù)返回上一頁(yè)

Navigator.of(context).pop('result value');

2 路由的方式 實(shí)現(xiàn)頁(yè)面跳轉(zhuǎn)與返回

2.1 路由配置

在MaterialApp或CupertinoApp中配置路由名稱和頁(yè)面的對(duì)應(yīng)關(guān)系：

initialRoute
onGenerateRoute
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(primaryColor: Colors.red),
      // 默認(rèn)展示的頁(yè)面路由
      initialRoute: "/",
      onGenerateRoute: (settings) {
        final routeName = settings.name;
        dynamic arguments = settings.arguments;

        switch (routeName) {
          case "/":
            return CupertinoPageRoute(builder: (context) => const RootPage());
          case "/page1":
            // 可接收參數(shù)
            String? param = arguments as String?;
            return CupertinoPageRoute(
                builder: (context) => Page1(param: param));
          default:
            return CupertinoPageRoute(
              builder: (_) => Scaffold(
                body: Center(
                  child: Text('UnknownScreen $routeName'),
                ),
              ),
            );
        }
      },
    );
  }
}

2.2 攜帶參數(shù)跳轉(zhuǎn)頁(yè)面 并獲取返回值

普通跳轉(zhuǎn)

Navigator.pushNamed(context, '/page1');

傳參

Navigator.pushNamed(context, '/page1',arguments: 'param');

獲取返回值

var result = await Navigator.pushNamed(context, '/page1', arguments: 'param');

2.3 跳轉(zhuǎn)或返回指定頁(yè)面并清空棧

銷毀當(dāng)前頁(yè)面并跳轉(zhuǎn)新的頁(yè)面

Navigator.popAndPushNamed(context, '/page2');

返回指定頁(yè)面

// 返回指定頁(yè)面
Navigator.popUntil(context, (route) => route.settings.name == '/');
// 返回根頁(yè)面
Navigator.popUntil(context, (route) => route.isFirst);

跳轉(zhuǎn)至某頁(yè)面，并銷毀之前的頁(yè)面

Navigator.pushNamedAndRemoveUntil(
                      context, '/page2', (route) => route.settings.name == '/');

3 返回指定頁(yè)面（跨多個(gè)頁(yè)面）并傳遞返回值

配置路由時(shí) 添加一個(gè)參數(shù) Map()

 switch (routeName) {
   case "/":
     return CupertinoPageRoute(
       settings: RouteSettings(
         name: "/",
         arguments: Map(), //用于 popUntil 返回傳值
       ),
       builder: (context) => const RootPage(),
     );
   ...
 }

返回指定頁(yè)面 ’/’

 Navigator.popUntil(context, (route) {
   if (route.settings.name == '/') {
     (route.settings.arguments as Map)['result'] = '返回值';
     return true;
   } else {
     return false;
   }
 });

‘/’ 頁(yè)面 獲取返回值

 await Navigator.of(context).pushNamed('/page2');
 if (mounted) {
   final arguments =
       ModalRoute.of(context)?.settings.arguments as Map;
   final result = arguments['result'];
 }
