⚡ 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

AnimatorSet Supported properties

PropertyMeanDefault
childThe component that performs the animationnot have
animatorSetCollection of animationnot have
animationTypeControls the type of animation executionAnimationType.repeat
debugThe output logfalse

The properties of the animationType

PropertyMean
repeatRepeat animation
reverseRewind animation
onceOne play animation
AnimatorSet(
    child: widget.child,
    animatorSet: [],
    animationType: AnimationType.reverse,
    debug: false,
)

3、use AnimatorSet api

⚡ For Example

1、create timeLine


  1. This figure shows that the core components of the animation are made according to the timeLine
  2. In the process of execution, there are 6 animations simultaneously, and the total animation duration is 900ms
  3. ScaleY components are used to scale up and down in order to make each rectangle have a wave effect
  4. Drag the timeline with the Delay component to reach the animation duration of 900ms

2、build animatorSet

Assemble our animation component using the diagram above, which has the following properties

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

The object that the animation executes is Container rectangle

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),
    ],
  );
}

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, uses the Serial Widget

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),
        ],
      ),
    ],
  );
}
