flutter-原生路由傳自定義對象

自定義對象

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

傳值

Navigator.push(
        context,
        MaterialPageRoute(
        builder: (context) => DangkouMsg(),
        settings: RouteSettings(arguments: dk),
        ), //原生路由傳對象
);

目標頁面

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

 擴展

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

寫在build外面會報錯

解決方式

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