destination library
Calculates a destination Point given an origin, distance, and bearing.
Classes
- BBox

Please make sure, you arrange your parameters like this:
Longitude 1, Latitude 1, Altitude 1 (optional), Longitude 2, Latitude 2, Altitude 2 (optional)
You can either specify 4 or 6 parameters
If you are using the default constructor with two dimensional positions (lng + lat only), please use the constructor like this:
BBox(lng1, lat1, lng2, lat2); - CoordinateType

Functions

calculateRhumbDestination(
Position origin, num distance, num bearing, [num radius = earthRadius]) → Position -
destination(
Point origin, num distance, num bearing, [Unit unit = Unit.kilometers]) → Point - Takes a Point and calculates the location of a destination point given a distance in degrees, radians, miles, or kilometers; and bearing in degrees. This uses the Haversine formula to account for global curvature. For example:
-
destinationRaw(
Position origin, num distance, num bearing, [Unit unit = Unit.kilometers]) → Position -
rhumbDestination(
Point origin, num distance, num bearing, {Unit? unit = Unit.kilometers, Map< String, dynamic> ? properties}) → Feature<Point> - Returns the destination Point having traveled the given distance along a Rhumb line from the origin Point with the (variant) given bearing.
