@override String? buildCondition()

Implementation

@override
String? buildCondition() {
  List<QueryCond> flatList = [];
  for (QueryCond q in conditions) {
    switch (q) {
      case FieldCond fc:
        flatList.add(fc);
      case AndCond ac:
        flatList.add(ac);
      case OrCond oc:
        flatList.addAll(oc.conditions);
    }
  }
  List<String> ls = flatList.mapList((e) => e.buildCondition()).nonNullList.filter((e) => e.isNotEmpty);
  if (ls.isEmpty) return null;
  if (ls.length == 1) return ls.first;
  String s = ls.join(',');
  return "[$s]";
