跳转并销毁页面

onPressed: () {
    Navigator.pushNamedAndRemoveUntil(context, "homeRoute", (route) => route == null);
}
最后的函数也可以用(Route router) => false

Navigator.pushAndRemoveUntil(
                                context,
                                MaterialPageRoute(
                                    builder: (_) => DetailShow(topic: topic)),
                                ModalRoute.withName('/'));
