flutter 命名路由传参

需要展示的页面

class BreachDetailVC extends StatefulWidget {
  String breachApplyId = "";

  BreachDetailVC({Key? key}) : super(key: key);
  BreachDetailVC.needId({Key? key, required this.breachApplyId}) : super(key: key);

  @override
  State createState() => _BreachDetailVCState();
}

class _BreachDetailVCState extends State {
    @override
//在 initState写 获取参数的代码会报错
//breachApplyId是传入的参数
  void didChangeDependencies() {
    super.didChangeDependencies();

    RouteSettings sttings =  ModalRoute.of(context)!.settings!;
    var args=sttings!.arguments;
    Map params = args as Map;
    this.widget.breachApplyId = params["breachApplyId"];
    print(args);
    print("breachApplyId" + this.widget.breachApplyId);

    queryData();
  }
}

//路由配置

class MyBreahRouteGenerator {
  static final routes = {
    "/breachList/detail":(context) => BreachDetailVC(),
//    "/breachList/detail":(context, {arguments}) => BreachDetailVC(),

  };
}

//跳转代码

Navigator.pushNamed(context, '/breachList/detail', arguments: {
     "breachApplyId" : this.widget.model["breachApplyId"]
   });
