Methods
-
copyWith(
{Geographic? position}) → SphericalRhumbLine -
Copy this geodetic object with an optional
position
changed. -
destinationPoint(
{required double distance, required double bearing, double radius = 6371000.0}) → Geographic - Returns the destination point having travelled along a rhumb line from the current position the given distance on the given bearing.
-
distanceTo(
Geographic destination, {double radius = 6371000.0}) → double -
Returns the distance from the current
position
todestination
along a rhumb line. -
finalBearingTo(
Geographic destination) → double -
Returns the bearing from the current position to
destination
along a rhumb line. -
initialBearingTo(
Geographic destination) → double -
Returns the bearing from the current position to
destination
along a rhumb line. -
midPointTo(
Geographic destination) → Geographic -
Returns the loxodromic midpoint (along a rhumb line) between the current
position and
destination
. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

toString(
) → String -
