getClosestAddressLandmark method

Future<Landmark?> getClosestAddressLandmark({ required Coordinates coords, required int radius, required bool onlyCity, })

Retrieves the closest address landmark to the given coordinates within a specified radius.

Parameters

• coords: The geographic coordinates to search around.
• radius: The radius in meters within which to search for the closest address.
• onlyCity: Specifies whether to only search for addresses within cities.

Returns

• The closest Landmark representing the address if found, otherwise null.

Implementation

Future<Landmark?> getClosestAddressLandmark({
  required Coordinates coords,
  required int radius,
  required bool onlyCity,
}) async {
  final String? resultString = await GemKitPlatform.instance
      .getChannel(mapId: mapId)
      .invokeMethod<String>(
        'callObjectMethod',
        jsonEncode(<String, dynamic>{
          'id': _pointerId,
          'class': 'MapView',
          'method': 'getClosestAddress',
          'args': <String, dynamic>{
            'c': coords,
            'radius': radius,
            'onlyCity': onlyCity,
          },
        }),
      );

  if (resultString == null) {
    return null;
  }

  final int id = jsonDecode(resultString)['result'];
  if (id == -1) {
    return null;
  } else {
    return Landmark.init(id);
