flutter bloc go_route 对象传参

1. 路由

   GoRoute(
      name: 'login',
      path: '/login',
      builder: (BuildContext context, GoRouterState state) {
        //对象传值
        User user = state.extra as User;
        return LoginPage(
          user: user,
        );
      },
    ),

2. 如何使用,以下使用例子

   @override
   Widget build(BuildContext context) {
    return AppBar(
      leading: IconButton(
        onPressed: () => {
          context.pushNamed('login',
              extra: context.read<UserBloc>().state.data!.first)
        },
        icon: const Icon(Icons.apps),
      ),

效果图

 @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text(widget.user.name),
          leading: IconButton(
            onPressed: () => Navigator.pop(context),
            icon: const Icon(Icons.arrow_back_outlined),
          ),
        ),
