ArmPainterSide class

A widget to show the profile view of the arm.

This viewpoint shits as the arm swivels, so that it is always looking at the shoulder, elbow, and wrist head-on. To visualize the swivel, see ArmPainterTop.

getter/setter pair
radiusColor ↔ Color
Color to paint the radius in
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
screen ↔ double

Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
getArmCoordinates(ArmAngles angles, Size size) → ArmCoordinates
Performs forward kinematics to get the coordinates of each joint from the angles.
getRelativeOffset(Size size, Offset absolute) → Offset
Converts an absolute offset within this widget to a relative offset about the shoulder joint.
hitTest(Offset position) → bool?
Called whenever a hit test is being performed on an object that is using this custom paint delegate.
inherited
ik(Size size, Offset relative) → ArmAngles?
Performs inverse kinematics to get the angles of the arm from the desired position.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Size size) → void
Called whenever the object needs to paint. The given Canvas has its coordinate space configured such that the origin is at the top left of the box. The area of the box is the size of the size argument.
override
paintArm(Canvas canvas, Size size, ArmCoordinates coordinates, {double opacity = 1}) → void
Paints the arm given its joint positions.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies when it is time to repaint.
inherited
shouldRebuildSemantics(covariant CustomPainter oldDelegate) → bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
inherited
shouldRepaint(covariant CustomPainter oldDelegate) → bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
override
toAbsolute(double relative) → double
Converts from -1, 1 relative coordinates to screen coordinates.
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
inherited

Constants

elbowLength → const double
The relative length of the elbow-wrist segment.
gripperLength → const double
The relative length of the gripper.
shoulderLength → const double
The relative length of the shoulder-elbow segment.
totalArmLength → const double
The total relative length of the arm.
