Null check operator used on a null value

[LvJson]

I found the reason for the error.

If i set navigatorObservers,it will throw exception.

GetMaterialApp(
              navigatorObservers: [
                GetXRouterObserver()
              ],
            )


class GetXRouterObserver extends NavigatorObserver {
  @override
  void didPush(Route<dynamic> route, Route<dynamic>? previousRoute) {
    RouterReportManager.reportCurrentRoute(route);
  }

  @override
  void didPop(Route<dynamic> route, Route<dynamic>? previousRoute) async {
    RouterReportManager.reportRouteDispose(route);
  }
}

有办法在不移除这个observer的情况下解决这个bug吗？

我这边有个问题：我想在路由之前判断用户是否登录，如果没登录我路由就不跳转，但是中间件必须要返回一个RoutSetting，因此我想着监听路由跳转，加了observer，但是碰到跟你一样 的报错。
