getAngle(double x0, double y0, double x1, double y1) → double: Get an angle (radians) between two points.
getAngliness(double x0, double y0, double x1, double y1) → double: Get a normal value representing how close two points are from being at a 45 degree angle.
getArrow(double x0, double y0, double x1, double y1, {double bow = 0, double stretchMin = 0, double stretchMax = 420, double stretch = 0.5, double padStart = 0, double padEnd = 0, bool flip = false, bool straights = true, ArcDirection arcDirection = ArcDirection.Auto}) → Arrow
getDistance(double x0, double y0, double x1, double y1) → double: Get the distance between two points.
getPointBetween(double x0, double y0, double x1, double y1, {double d = 0.5}) → List<double>: Get a point between two points.
getSector(double angle, {double doubleberOfSectors = 8}) → int: Get the sector of an angle (e.g. quadrant, octant)
mod(double value, List<double> a, List<double> b, {bool clamp = false}) → double: Modulate a value between two ranges
projectPoint(double x0, double y0, double angle, double distance) → List<double>: Move a point in an angle by a distance.
rotatePoint(double x, double y, double cx, double cy, double angle) → List<double>: Rotate a point around a center.
