MultiTween<P> class

Animatable that animates multiple properties at once. It can also chain multiples Tweens for a property.

Example: (using supercharged)

// Define your animation properties somewhere
enum AniProps { width, height, color }

// Create MultiTween based on your enum
final tween = MultiTween<AniProps>()
  ..add(AniProps.width, 0.0.tweenTo(100.0), 1000.milliseconds)
  ..add(AniProps.width, 100.0.tweenTo(200.0), 500.milliseconds)
  ..add(AniProps.height, 0.0.tweenTo(200.0), 2500.milliseconds)
  ..add(AniProps.color, Colors.red.tweenTo(Colors.blue), 3.seconds);

For details on the add method: MultiTween.add.

If you don't want to define your own enum, you can use DefaultAnimationProperties that comes with MultiTween.

Methods

add(P property, Animatable tween, [Duration duration = const Duration(seconds: 1), Curve curve = Curves.linear]) → void
Adds a new tweening task for a specified property.
animate(Animation<double> parent) Animation<MultiTweenValues<P>>
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<MultiTweenValues<P>>
Returns a new Animatable whose value is determined by first evaluating the given parent and then evaluating this object.
inherited
evaluate(Animation<double> animation) MultiTweenValues<P>
The current value of this object for the given Animation.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
