Easy to build an animation set

✨ Flutter Animation Set

[Lanuage ~~] English | 中文文档

Simplified Flutter stagger animation.To drive the Flutter stagger animation through a timeline in the form of an animation configuration.You can

1. Uses the existing Animation Widget of Flutter Animation Set
2. Use Flutter Animation Set to create a new Animation Widget
3. Contribute your Flutter Animation Set Widget
4. Watch All of the Curves of Flutter in example

🎖 Installing

dependencies:
  flutter_animation_set: ^0.0.3

⚡ Use Animation Set Widget

1、import

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

2、use

child: YYRotatingPlane(),

⚡ 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

Assemble the animation using an AnimatorSet Widget

• child:The component that executes the animation
• animatorSet:Collection of animation

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

3、use api

about animation widget

Widget	Mean	Description
W	width	Control the change of width. If it is scaled up, SX is recommended instead
H	height	Control the change of height. If it is scaled up, SY is recommended instead
P	padding	Control padding changes
O	opacity	Control opacity changes
SX	scaleX	Scale the X-axis with the midpoint
SY	scaleY	Scale the Y-axis with the midpoint
RX	rotateX	Rotate the X-axis with the midpoint
RY	rotateY	Rotate the Y-axis with the midpoint
RZ	rotateZ	Rotate the Z-axis with the midpoint
TX	transitionX	Translate the Z-axis with the midpoint
TY	transitionY	Translate the Y-axis with the midpoint
C	color	Control background color changes
B	border	Control background border changes

about support widget

Widget	Mean	Description
Delay	delay timeLine	Extend the timeline to wait
Serial	combine animation	Through the combination of animation, to achieve the effect of playing together

⚡ For Example

1、create timeLine

1. This figure shows that the composition of the animation is made according to the timeLine
2. If you need to extend the time line, use the Delay Widget to extend the line; the duration property is the extended time
3. If you need to combine various animations, use the Serial Widget to do so, the duration property being the time of the composition

2、build animatorSet

Assemble our animation components by the above icon, just need to control the time of Delay

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:Animation initial value
• to:End of animation value
• duration:Animation time
• delay:The delay in actually executing the animation
• curve:Animation interpolator

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),
        ],
      ),
    );
  }
}

More

1、Combination of animation

The scaling effect requires scaling both the X and Y axes

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),
      O(from: 0.5, to: 0.0, delay: 1000, curve: Curves.easeInOut),
    ],
  ),
],

done

2、Time-lapse animations

Deal with the delay attribute when you actually do the animation

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、Reverse animation

After the animation can be played, set animationtype.reverse through the animationType property, making the animation play back

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),
        ],
      ),
    ],
  );
}
