Methods
-
animate(
Animation< double> parent) → Animation<Alignment> -
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<Alignment> -
Returns a new Animatable whose value is determined by first evaluating
the given parent and then evaluating this object.
inherited
-
evaluate(
Animation< double> animation) → Alignment -
The current value of this object for the given Animation.
inherited
-
lerp(
double t) → Alignment -
Returns the value this variable has at the given animation clock value.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
