StepTween class

An interpolation between two integers that floors.

This class specializes the interpolation of Tween<int> to be appropriate for integers by interpolating between the given begin and end values and then using double.floor to return the current integer component, dropping the fractional component.

This results in a value that is never greater than the equivalent value from a linear double interpolation. Compare to IntTween.

See Tween for a discussion on how to use interpolation objects.



StepTween({int begin, int end})
Creates an int tween that floors. [...]


begin int

read / write, inherited
hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited


lerp(double t) int
Returns the value this variable has at the given animation clock value. [...]
animate(Animation<double> parent) Animation<int>
Returns a new Animation that is driven by the given animation but that takes on values determined by this object. [...]
chain(Animatable<double> parent) Animatable<int>
Returns a new Animatable whose value is determined by first evaluating the given parent and then evaluating this object. [...]
evaluate(Animation<double> animation) int
The current value of this object for the given Animation. [...]
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
toString() String
Returns a string representation of this object.
transform(double t) int
Returns the interpolated value for the current value of the given animation. [...]


operator ==(dynamic other) bool
