TimelineTween<T> class
Animatable that handles complex animations which handles multiple properties or scenes.
You can specify a default curve for the tween by setting curve.
Example: (using supercharged)
enum Prop { width, height, color }
var timeline = TimelineTween<Prop>();
timeline
.addScene(begin: 0.seconds, duration: 1.seconds)
.animate(Prop.width, tween: 100.0.tweenTo(200.0))
.animate(Prop.height, tween: 50.0.tweenTo(100.0));
timeline
.addScene(begin: 1.2.seconds, end: 2.seconds)
.animate(Prop.color, tween: Colors.black.tweenTo(Colors.black));

Properties
Methods
-
addScene(
{Duration? begin, Duration? duration, Duration? end, Curve? curve}) → TimelineScene< T> - Adds a new scene to the timeline. A scene is specified with a time span. The time span can be set by providing either
-
animate(
Animation< double> parent) → Animation<TimelineValue< T> > -
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<TimelineValue< T> > -
Returns a new Animatable whose value is determined by first evaluating
the given parent and then evaluating this object.
inherited
-
evaluate(
Animation< double> animation) → TimelineValue<T> -
The current value of this object for the given Animation.
inherited
-
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) → TimelineValue< T> -
Computes the tween
