regionHash method

@override List<String> regionHash([ double radius = 1.0 ])

Returns a hash list in the area by passing radius.

Implementation

@override
List<String> regionHash([double radius = 1.0]) {
  if (radius <= 0) {
    return const [];
  }
  final precision = _GeoUtility.setPrecision(radius);
  final centerHash = hash.substring(0, precision);
  return _GeoFirePoint.neighborsOf(hash: centerHash)..add(centerHash);
}
