flutter原生路由传自定义对象

自定义对象

class Dk {
  int id;
  String title;
  String address;
  String ww;
  String account;
}

传值

Navigator.push(
        context,
        MaterialPageRoute(
        builder: (context) => DangkouMsg(),
        settings: RouteSettings(arguments: dk),
        ), //原生路由传对象
);

目标页面

Widget build(BuildContext context) {
    DK dk = ModalRoute.of(context).settings.arguments;
}

 扩展

dk = ModalRoute.of(context).settings.arguments;

写在build外面会报错

解决方式

 @override
  void initState() {
    super.initState();
    SchedulerBinding.instance.addPostFrameCallback(
      (_) => {
        showAlbumList = ModalRoute.of(context).settings.arguments,
        setState(() {}),
      },
    );
  }
