Implementation
Future<List<int>> distanceSearch(List<LatLng> origins, LatLng target, DistanceSearchType type) async {
List<Map<String, dynamic>> oriList = [];
origins.forEach((o) {
oriList.add(o.toJson());
});
Map<String, dynamic> params = {
"origin": oriList,
"target": target.toJson(),
"type": DistanceSearchType.values.indexOf(type),
};
List<dynamic> result = await _searchChannel.invokeMethod("tool#distanceSearch", params);
return result.map((v) => v as int).toList();
}
