🚀 Stateless Animation

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

Example: Square with an animated background color.

import 'package:flutter/material.dart';
import 'package:simple_animations/simple_animations.dart';
import 'package:supercharged/supercharged.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // create animation widget with type of animated variable
    return PlayAnimation<Color?>(
        tween: Colors.red.tweenTo(Colors.blue), // define tween
        duration: 2.seconds, // define duration
        builder: (context, child, value) {
          return Container(
            color: value, // use animated value
            width: 100,
            height: 100,
          );
        });
  }
}

Note: We use supercharged extensions here. If you don't like it, refer to this dependency-less example.

🎭 Timeline Tween

Timeline Tween is a mighty tool that enables you to tween multiple properties or designing staggered animations in a single Animatable.

Example: Custom tween with multiple properties.

import 'package:flutter/material.dart';
import 'package:simple_animations/simple_animations.dart';
import 'package:supercharged/supercharged.dart';

// define animated properties
enum AniProps { width, height, color }

// design tween by composing scenes
final tween = TimelineTween<AniProps>()
  ..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));

Note: We use supercharged extensions here. If you don't like it, refer to this dependency-less example.

🎥 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.

import 'package:flutter/material.dart';
import 'package:simple_animations/simple_animations.dart';
import 'package:supercharged/supercharged.dart';

class MyWidget extends StatefulWidget {
  @override
  _MyWidgetState createState() => _MyWidgetState();
}

// add AnimationMixin to widget's state
class _MyWidgetState extends State<MyWidget> with AnimationMixin {
  // declare animation variable
  late Animation<double> size;

  @override
  void initState() {
    // connect tween and controller and apply to animation variable
    size = 0.0.tweenTo(200.0).animatedBy(controller);

    controller.play(); // start the animation playback

    super.initState();
  }

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

⏯ Animation Developer Tools

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

devtools

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