🚀 Stateless Animation

Stateless Animation provides your app with a powerful set of Flutter widgets that hide the most complex part of creating animations.

Example: Square with a animated, fading background color.

PlayAnimation<Color>( // <-- specify type of animated variable
  tween: Colors.red.tweenTo(Colors.blue), // <-- define tween of colors
  builder: (context, child, value) { // <-- builder function
    return Container(
        color: value, // <-- use animated value
        width: 100, 
        height: 100
    );
});

🎭 MultiTween

MultiTween gives is mighty tool thats enables you to tween multiple properties in a single Animatable or designing staggered animations.

Example: Custom tween with multiple properties.

enum AniProps { width, height, color } // <-- define properties

class MyWidget extends StatelessWidget {

  final _tween = MultiTween<AniProps>() // <-- design tween
    ..add(AniProps.width, 0.0.tweenTo(400.0), 1000.milliseconds)
    ..add(AniProps.width, 400.0.tweenTo(300.0), 1000.milliseconds)
    ..add(AniProps.height, 500.0.tweenTo(200.0), 2000.milliseconds)
    ..add(AniProps.color, Colors.red.tweenTo(Colors.blue), 2.seconds);

  @override
  Widget build(BuildContext context) {
    return ... // <-- use tween
  }
}

🎥 Anicoto

Anicoto fully manages your AnimationController instances and handles initialization, configuration and disposing. No more boilerplate code.

Example: Animated stateful widget with full-fledged AnimationController instance.

class _MyAnimatedWidgetState extends State<MyAnimatedWidget>
    with AnimationMixin {  // <-- add AnimationMixin to state class

  Animation<double> size; // <-- declare animation variable

  @override
  void initState() {
    size = 0.0.tweenTo(200.0).animatedBy(controller); // <-- connect tween and controller and apply to animation variable
    controller.play(); // <-- start the animation playback
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      width: size.value, // <-- use animation variable's value here 
      height: size.value, // <-- use animation variable's value here
      color: Colors.red
    );
  }
