          if (result != null && result.data!['logout'] == true) {

              ),
            );
            Future.delayed(const Duration(seconds: 1)).then((value) {
              user = Hive.box<User>('currentUser');
              url = Hive.box('url');
              final androidFirebaseOptionsBox =
                  Hive.box('androidFirebaseOptions');
              final iosFirebaseOptionsBox = Hive.box('iosFirebaseOptions');
              organisation = Hive.box<OrgInfo>('currentOrg');
