MotionSpline class

The spline motion is used to animate a point along a spline definied by a set of points.

Inheritance

Constructors

MotionSpline({required PointSetterCallback setter, required List<Offset> points, required double duration, Curve? curve}): Creates a new spline motion with a set of points. The setter is a callback for setting the positions, points define the spline, and duration is the time for the motion to complete. Optionally a curve can be used for easing.

curve ↔ Curve?: The animation curve used to ease the animation.
getter/setter pairinherited
duration → double: The total time it will take to complete the motion, in seconds.
no setterinherited
hashCode → int: The hash code for this object.
no setterinherited
isFinished → bool: Returns true if the Motion has completed.
no setterinherited
points → List<Offset>: A list of points that define the spline.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
setter → PointSetterCallback: The callback used to update a point when the motion is run.
final
tension ↔ double: The tension of the spline, defines the roundness of the curve.

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
step(double dt) → void: Moves to the next time step in an motion, dt is the delta time since the last time step in seconds. Typically this method is called from the MotionController.
inherited
toString() → String: A string representation of this object.
inherited
update(double t) → void: Sets the motion to a specific point in time. The t value that is passed in is a normalized value 0.0 to 1.0 of the duration of the motion. Every motion will always recieve a callback with the end time point (1.0), unless it is cancelled.
