🍹 Liquid

Liquid provides ready-to-use, stunning visual animations that can be explored and configured with Liquid Studio.

🚀 Stateless Animation

Stateless Animation provides 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
  builder: (context, child, value) { // <-- builder function
    return Container(
        color: value, // <-- use animated value
        width: 100, 
        height: 100
    );
});

🎭 Timeline Tween

Timeline Tween (successor of MultiTween) is a mighty tool thats enables you to tween multiple properties or designing staggered animations in a single Animatable.

Example: Custom tween with multiple properties.

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

class MyWidget extends StatelessWidget {

  final _tween = TimelineTween<AniProps>() // <-- design tween
    ..addScene(begin: 0.milliseconds, duration: 500.milliseconds)
        .animate(AniProps.width, tween: 0.0.tweenTo(400.0))
        .animate(AniProps.height, tween: 500.0.tweenTo(200.0))
        .animate(AniProps.color, tween: Colors.red.tweenTo(Colors.yellow))
    ..addScene(begin: 700.milliseconds, end: 1200.milliseconds)
        .animate(AniProps.width, tween: 400.0.tweenTo(500.0));

  @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
    );
  }
}

⏯ Animation Developer Tools

Tired of watching the same animation over and over again, in order to fine tune it?

The Animation Developer Tools allows you pause anywhere, scroll around, speed up, slow down or focus on a certain interval of the animation.
