Methods

contains(Coord point, [num error = kDefaultError]) → bool

distanceFromPoint(Coord point) → num

evaluate(Coord point) → num

intersect(Line line, [num error = kDefaultError]) → Coord?

Returns null if lines are parallel

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

perpendicular(Coord point) → Line

Perpendicular line passing through point.

perpendicularFoot(Coord point) → Coord

Value of the perpendicular foot from a point on the line. i.e the intersection of the perpendicular

pointOnLineClosestTo(Coord point) → Coord

pointsOnLineFromPoint(Coord point, num distance) → (Coord, Coord)

Returns two coords equal distance, distance from the given point on the line.

pointXDirectionToLine(Coord point) → num?

Returns -1 for left, 1 for right and 0 in case the point lies on the line and null in case the line is horizontal.

rotate(Coord point, Angle theta, [bool antiClockwise = true]) → Line

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
