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.

Installation

Add this to your package’s pubspec.yaml file, And execute the commandflutter pub get:

dependencies:

  zerker: <latest_version_here>

Getting started

Import the package

import 'package:zerker/zerker.dart';

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")
	..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);
