IntTween class Null safety

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.



IntTween({int? begin, int? end})
Creates an int tween.


begin int?
The value this variable has at the beginning of the animation.
read / write, inherited
end int?
The value this variable has at the end of the animation.
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


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.
lerp(double t) int
Returns the value this variable has at the given animation clock value.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
toString() String
A string representation of this object.
transform(double t) int
Returns the interpolated value for the current value of the given animation.


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