remove method

TQuery remove(ModelGeoValue? value)

Remove from filtering only those elements that are contained within the range of adjacent GeoHashes of value.

valueの隣り合うGeoHashの範囲内に含む要素のみをフィルタリングから削除します。

Implementation

TQuery remove(ModelGeoValue? value) {
  if (value == null) {
    return _toQuery(_modelQuery);
  }
  final sourceNeighbors = _modelQuery.filters
      .firstWhereOrNull(
        (element) => element.key == key,
      )
      ?.value as List<String>?;

  sourceNeighbors?.remove(value.value.geoHash);
  for (final hash in value.value.neighbors) {
    sourceNeighbors?.remove(hash);
  }
  return _toQuery(
    _modelQuery.geo(
      key,
      sourceNeighbors?.distinct().sortTo((a, b) => a.compareTo(b)) ?? [],
    ),
  );
}
