areaBetweenCoordinates method

Future<double> areaBetweenCoordinates (
  1. BMFCoordinate leftTop,
  2. BMFCoordinate rightBottom
)

计算地理矩形区域的面积

BMFCoordinate leftTop 左上角经纬度坐标点

BMFCoordinate rightBottom 右下角经纬度坐标点

返回区域面积，单位：平方米

Implementation

static Future<double> areaBetweenCoordinates(
    BMFCoordinate leftTop, BMFCoordinate rightBottom) async {
  return await BMFUtilsCalculateDispatcher.areaBetweenCoordinatesDispatcher(
      _calcChannel, leftTop, rightBottom);
}
