- Getting Started with Coding

To use this library, import package:particular/particular.dart.
Follow these steps to integrate the particles system into your Flutter app:
I. Initialize the Particles Controller in initState:

final _particleController = ParticularController();
...
@override
void initState() {
  // Load particle configs file
  String json = await rootBundle.loadString("assets/particle.json");
  final configsData = jsonDecode(json);

  // Load particle texture file
  ByteData  bytes = await rootBundle.load("assets/${configsData["textureFileName"]}");
  ui.Image texture = await loadUIImage(bytes.buffer.asUint8List());

  // Add particles layer
  _particleController.addLayer(
    texture: frameInfo.image, // Remove in default-texture case
    configsData: configsData, // Remove in programmatic configuration case
  );
  super.initState();
}

II. Add the Particular widget in your widget three:

@override
Widget build(BuildContext context) {
  return MaterialApp(
    home: Scaffold(
      backgroundColor: Colors.black,
      body: Particular(
        controller: _particleController,
      ),
    ),
  );
}

III. Live Update Particle Layer:

_particleController.layers.first.update(
    maxParticles: 100,
    lifespan:1.2,
    speed:100,
    angle:30,
);
