main.dart里面是不是要把系统所有的页面都要写进入，用if…else…if去判断？

MaterialPage? page设置为可空试试看：
RouteStatus getStatus(MaterialPage? page) {
if (page?.child is LoginPage) {
    return RouteStatus.login;
} else if (page?.child is RegistrationPage) {
    return RouteStatus.registration;
} else if (page?.child is BottomNavigator) {
    return RouteStatus.home;
} else if (page?.child is NoticePage) {
    return RouteStatus.notice;
} else if (page?.child is DarkModePage) {
    return RouteStatus.darkMode;
} else if (page?.child is VideoDetailPage) {
    return RouteStatus.detail;
} else {
    return RouteStatus.unknown;
}
}
