What is 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.

Useage

Create a zerker widget

class _MyHomePageState extends State<MyHomePage> {
  @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
  init() {
    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")
  ..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);
