[移动开发]Flutter Route路由跳转统一Page带参数

class MyRoutePath {
  static String twoPage = '/twoPage';
  static String homePage = '/homePage';
  static String thirdPage = '/thirdPage';
}

class MyRoute {
  static final Map<String, WidgetBuilder> sxRoutes = <String, WidgetBuilder>{
    MyRoutePath.twoPage: (context, {arguments}) => TwoPagePage(arguments:arguments),
    MyRoutePath.homePage: (context, {arguments}) => HomePagePage(arguments: arguments),
    MyRoutePath.thirdPage: (context, {arguments}) => ThirdPage(arguments: arguments),
  };

  static Route<dynamic> onGenerateRoute(RouteSettings settings) {
    return buildPage(settings.name, settings.arguments);
  }

  static Route<dynamic> buildPage(String settingsName, Object settingArguments) {
    final String name = settingsName;
    final Function pageContentBuilder = sxRoutes[name];
    final dynamic arguments = settingArguments;
    if (pageContentBuilder != null) {
      print('Page:===== ${pageContentBuilder}');
      if (arguments != null) {
        final Route route = MaterialPageRoute(builder: (BuildContext context) {
          return pageContentBuilder(context, arguments: arguments);
        });
        return route;
      } else {
        final Route route = MaterialPageRoute(builder: (BuildContext context) {
          return pageContentBuilder(context);
        });
        return route;
      }
    } else {
      print('没找到定义的路由');
    }
  }
}

使用

return MaterialApp(
...
onGenerateInitialRoutes: (settings) {
        return [
          MyRoute.buildPage(MyRoutePath.homePage, "我就是初始化参数"),
        ];
      },
      onGenerateRoute: (RouteSettings settings) {
        return MyRoute.onGenerateRoute(settings);
      },
}

HomePage

class HomePagePage extends StatelessWidget {
  final dynamic arguments;
  HomePagePage({this.arguments});
  }

这样可以省去每次在Page页面获取setting 的传过来的参数

dynamic obj = ModalRoute.of(context).settings.arguments;
