CubicLine class - signature library

Constructors

CubicLine({required OffsetPoint start, required Offset cpStart, required Offset cpEnd, required OffsetPoint end, Offset? upStartVector, Offset? upEndVector, double startSize = 0.0, double endSize = 0.0}): Based on Bezier Cubic curve. start point of curve. end point of curve. cpStart - control point of start vector. cpEnd - control point of end vector. startSize - size ratio at begin of curve. endSize - size ratio at end of curve. upStartVector - pre-calculated Up vector fo start point. upEndVector - pre-calculated Up vector of end point.

Properties

cpEnd → Offset: Control of end point
final
cpStart → Offset: Control of start point.
final
direction → double: The angle of this offset as radians clockwise from the positive x-axis, in the range -pi to pi, assuming positive values of the x-axis go to the right and positive values of the y-axis go down.

no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
start → OffsetPoint: Initial point of curve.
final
startSize ↔ double: Start ratio size of line.
getter/setter pair
upEndVector → Offset: Up vector of end point.
no setter
upStartVector → Offset: Up vector of start point.
