      return 1;
    }

  }

    final indexedMembers = memberList.asMap().entries.toList();
    indexedMembers.sort((a, b) {
      final roleComparison = roleRank(a.value.teamInfo.memberRole)
          .compareTo(roleRank(b.value.teamInfo.memberRole));
      return roleComparison != 0 ? roleComparison : a.key.compareTo(b.key);
    });
    for (var index = 0; index < indexedMembers.length; index++) {
