Easy to build an animation set

✨ Flutter Animation Set

简化Flutter交错动画。用动画配置的形式，通过时间线去驱动Flutter的交错动画。你可以

1. 使用Flutter Animation Set现有的动画组件
2. 使用Flutter Animation Set去创建新的动画组件
3. 贡献你的Flutter Animation Set动画组件

🎖 Installing

dependencies:
  flutter_animation_set: ^0.0.1

⚡ Use Animation Set Widget

1、import

import 'package:flutter_animation_set/widget/transition_animations.dart';
import 'package:flutter_animation_set/widget/behavior_animation.dart';

2、use

child: YYRotatingPlane(),

3、road map

⚡ Create Animation Set Widget By YourSelf

1、import

import 'package:flutter_animation_set/animation_set.dart';
import 'package:flutter_animation_set/animator.dart';

2、use widget

通过使用AnimatorSet组装动画

• child:执行动画的组件
• animatorSet：动画集合

AnimatorSet(
    child: widget.child
    animatorSet: [],
)

3、use api

about animation widget

Widget	Mean	Description
W	width	控制宽度的变化，如果是按比例拉升，建议用SX替代
H	height	控制高度的变化，如果是按比例拉升，建议用SY替代
P	padding	控制边距的变化
O	opacity	控制透明度的变化
SX	scaleX	以中点进行X轴的缩放
SY	scaleY	以中点进行Y轴的缩放
RX	rotateX	以中点进行X轴的旋转
RY	rotateY	以中点进行Y轴的旋转
RZ	rotateZ	以中点进行Z轴的旋转
TX	transitionX	进行X轴的平移
TY	transitionY	进行Y轴的平移
C	color	控制背景颜色变化
B	border	控制背景边框变化

about support widget

Widget	Mean	Description
Delay	delay timeLine	延长时间线，进入等待阶段
Serial	combine animation	通过组合动画，达到通知播放的效果

⚡ For Example

1、create timeLine

1. 此图表明动画的组成是根据时间线(timeLine)去制作的
2. 如果需要延长时间线，就用Delay组件去拖长时间线，duration属性为延长的时间
3. 如果需要组合各种动画，就用Serial组件去组合动画，Serial的duration属性为组合动画时间

2、build animatorSet

通过上面的图示组装我们的动画组件，只需要控制好Delay的时间即可

Widget makeWave(int before, int after) {
  return AnimatorSet(
    child: Container(
      color: Colors.white,
      width: 5,
      height: 15,
    ),
    animatorSet: [
      Delay(duration: before),
      SY(from: 0.8, to: 1.6, duration: 200, delay: 0, curve: Curves.linear),
      SY(from: 1.6, to: 0.8, duration: 200, delay: 0, curve: Curves.linear),
      Delay(duration: after),
    ],
  );
}

• from:动画初始值
• to:动画结束值
• duration:动画时间
• delay:真正执行动画的延时
• curve:动画插值器

3、convert to code

class YYWave extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      width: 40,
      height: 40,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          makeWave(0, 500),
          makeWave(100, 400),
          makeWave(200, 300),
          makeWave(300, 200),
          makeWave(400, 100),
          makeWave(500, 0),
        ],
      ),
    );
  }
}

4、done

More

1、组合动画

缩放效果需要同时缩放X、Y轴

animatorSet: [
  Serial(
    duration: 2000,
    serialList: [
      SX(from: 0.0, to: 1.0, curve: Curves.easeInOut),
      SY(from: 0.0, to: 1.0, curve: Curves.easeInOut),
    ],
  ),
],

2、延时动画

对真正做动画的时候处理delay属性

class YYThreeLine extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      width: 40,
      height: 40,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          makeLine(0),
          makeLine(50),
          makeLine(100),
        ],
      ),
    );
  }
}

Widget makeLine(int delay) {
  return AnimatorSet(
    child: Container(
      color: Colors.white,
      width: 10,
      height: 5,
    ),
    animatorSet: [
      TY(
        from: 0.0,
        to: 5.0,
        duration: 400,
        delay: delay,
        curve: Curves.fastOutSlowIn,
      ),
      TY(
        from: 5.0,
        to: 0.0,
        duration: 400,
        curve: Curves.fastOutSlowIn,
      ),
    ],
  );
}

done

3、倒退动画

动画可以播放完成后，通过animationType属性设置AnimationType.reverse，让动画接着倒退播放

class YYFoldMenu extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      width: 40,
      height: 40,
      child: Column(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          makeFoldMenu(0, 40),
          makeFoldMenu(100, 26.0),
          makeFoldMenu(200, 12.0),
        ],
      ),
    );
  }
}

Widget makeFoldMenu(int delay, double toY) {
  return AnimatorSet(
    animationType: AnimationType.reverse,
    child: Container(
      decoration: BoxDecoration(
        color: Colors.white,
      ),
      width: 30,
      height: 10,
    ),
    animatorSet: [
      Serial(
        duration: 2000,
        delay: delay,
        serialList: [
          TY(from: 0.0, to: toY, curve: Curves.elasticInOut),
          SX(from: 1.0, to: 0.1, curve: Curves.elasticInOut),
          SY(from: 1.0, to: 0.1, curve: Curves.elasticInOut),
        ],
      ),
    ],
  );
}
