Not sure whether its an optimal way of performing a query in Firestore but i only found this way. You can query a map but you will need both the personId as well as personName

Future<void> memberList() async {
      List<Map> personList= new List<Map>();
      Map<String, dynamic> personData = new Map<String,dynamic>();
      personData ["personId"] = pid;
      personData ['personName'] = pname;
      personList.add(personData);
      QuerySnapshot query;
      query = await FirebaseFirestore.instance.collection('Group')
     .where('groupMembers',arrayContainsAny: personList).get();
 }
