Navigator 1.0 详细信息可以查看官网 给特定的 route 传参

一.定义路由名称

创建 routate_name.dart文件存储路由名称

///定义路由名字
class RotateName {
  static const String rootPage = "/";
  static const String loginPage = "LOGIN_PAGE";
}

二.定义路由

创建routate_map.dart

///存储路由关系的Map 将路由名称和页面对应
Map rotateMap = {
  RotateName.rootPage: (context) => const RootPage(),
  RotateName.loginPage: (context, {arguments}) =>
      LoginPage(arguments: arguments),
};

三.定义onGenerateRoute

有关onGenerateRoute的定义 查看onGenerateRoute

Route<dynamic> generateRoute(RouteSettings settings) {
    //获取rotateName
  final String? rotaName = settings.name;
//找到对应的页面
  final Function? buildPage = rotateMap[rotaName];
    //如果对应的页面是空的就返回一个空页面
  //MaterialPageRoute:页面切换方式为从下往上,
  //CupertinoPageRoute:页面切换方式从左往右 还可以自定义切换方式
  if (buildPage == null) {
    return MaterialPageRoute(
        builder: (_) => const Scaffold(
              body: Center(
                child: Text("Page Not Found!!!!"),
              ),
            ));
  }
  //查看携带的参数
  Map? args = settings.arguments as Map<dynamic, dynamic>?;
  if (args != null) {
    return MaterialPageRoute(
        builder: (context) => buildPage(context, args));
  }
  return MaterialPageRoute(builder: (context) => buildPage(context));
}

四.封装路由跳转方法 统一管理

class NavigatorUtils {
  //用 Navigator.pop() 回退到第一个路由
  static pop(BuildContext context, {Object? arguments}) {
    if (arguments == null) {
      Navigator.pop(context);
    } else {
      Navigator.pop(context, arguments);
    }
  }
  //用 Navigator.push() 跳转到第二个路由
  static push(BuildContext context, String routeName, {arguments}) async {
    final Function? buildPage = rotateMap[routeName];
    if (arguments != null) {
      return await Navigator.push(
          context,
          CupertinoPageRoute(
              builder: (context) => buildPage!(context, arguments: arguments),
              settings: RouteSettings(name: routeName)));
    } else {
      return await Navigator.push(
          context,
          CupertinoPageRoute(
              builder: (context) => buildPage!(context),
              settings: RouteSettings(name: routeName)));
    }
  }
//....还有其他方法都可以加进来
}

五.在Main.dart中修改

    return MaterialApp(
      title: 'Flutter Navigator1.0 Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      //之前定义的generateRoute
      onGenerateRoute: generateRoute,
      //初始页面页面名称为"/"
      initialRoute: RotateName.rootPage,
    );

六.使用

TextButton(
    onPressed: () {
      NavigatorUtils.push(context, RotateName.loginPage,arguments: {"name":"1122"});},
child: const Text("这里叫跳转"))
