A flexible and lightweight flutter canvas graphic animation library
Zerker
Zerker is a flexible and lightweight flutter Canvas graphic animation library.
With Zerker, you can create a lot of seemingly cumbersome animation effects, such as animated animations, pop-up animations, scene transitions, icon effects, and more.
At the same time, you can create a lot of simple games with Zerker. Zerker contains elements such as sprites, scrolling backgrounds, and atlases, making it easy to create game worlds with them.

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Zerker(app: MyZKApp(), clip: true, interactive: true, width: 350, height: 350),
));
}

Create your Zerker class inherited from ZKApp
class MyZKApp extends ZKApp {
@override

super.init();
/// init zerker scene
}
@override
update(int time) {
super.update(time);
sprite.position.x++;
}
}
Initialize the scene and create elements in the init function
/// Create a zerker sprite
ZKSprite bigboy = ZKSprite(key: "bigboy")
..position.x = size.width / 2
..position.y = size.height / 2
..animator.make("front", [0, 1, 2, 3, 4])
..animator.make("left", ['5-9'])
..animator.make("after", ['10-14'])
..animator.make("right", ['15-19'])
..onTapDown = (event) {
bigboy.animator.play("right", 8, true);
};
stage.addChild(bigboy);
/// Create a zerker text
ZKText text = ZKText()
..setPosition(100, 100)
..text = "hello world"
..setStyle(color: Colors.blueGrey, backgroundColor: Colors.red[50]);
stage.addChild(_text);
