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

Uses the existing Animation Widget of Flutter Animation Set

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



This figure shows that the core components of the animation are made according to the timeLine
In the process of execution, there are 6 animations simultaneously, and the total animation duration is 900ms
ScaleY components are used to scale up and down in order to make each rectangle have a wave effect
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),
],
copied to clipboard
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),
],
);
}
copied to clipboard
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),
],
),
);
}
}
copied to clipboard
4、done

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),
],
),
],
copied to clipboard
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,),
],
);
}
copied to clipboard
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),
],
),
],
);
}

done
