IntTween class
An interpolation between two integers that rounds.
This class specializes the interpolation of Tween<int> to be appropriate for integers by interpolating between the given begin and end values and then rounding the result to the nearest integer.
This is the closest approximation to a linear tween that is possible with an integer. Compare to StepTween and Tween<double>.
The begin and end values must be set to non-null values before calling lerp or transform.
See Tween for a discussion on how to use interpolation objects.

Methods
-
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.
inherited
-
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 at the result.
inherited
-
evaluate(
Animation< double> animation) → int -
The current value of this object for the given Animation.
inherited
-
lerp(
double t) → int -
Returns the value this variable has at the given animation clock value.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
transform(
double t) → int -
Returns the interpolated value for the current value of the given animation.

Operators

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