updateCoordinates method

Future<bool> updateCoordinates (
  1. List<BMFCoordinate> coordinates,
  2. {List<int> indexs}
)

更新经纬度数组

List<BMFCoordinate> coordinates polyline经纬度数组

indexs iO独有参数，分段索引(多纹理，多颜色折线请赋值), iOS在多颜色或者多纹理渲染的情况下，更新经纬度数组的同时，必须更新indexs

Implementation

Future<bool> updateCoordinates(List<BMFCoordinate> coordinates,
    {List<int> indexs}) async {
  if (null == coordinates) {
    return false;
  }

  bool ret = await BMFMapDispatcherFactory.instance.overlayDispatcher
      .updatePolylineMember(this.methodChannel, {
    'id': this.Id,
    'member': 'coordinates',
    'value': coordinates?.map((coordinate) => coordinate?.toMap())?.toList(),
    'indexs': indexs?.map((index) => index)?.toList()
  });

  if (ret) {
    this.coordinates = coordinates;
  }

  return ret;
}
