Whether you're a designer or developer, Particular empowers you to bring your creative visions with ease.

- Some Presets:

- Installation

Add particular to your pubspec.yaml file:
For detailed installation instructions, refer to the installation guide on pub.dev.

- Configurate your particles

You have two options for configuring your particles:

1. Using Editors:

Generate your particles system configurations by Particular Editor.

2. Programmatic Configuration:
   Manually configure your particle controller in code. Refer to the following steps for more details.

- Getting Started with Coding

Follow these steps to integrate the particles system into your Flutter app:

I. Insert Particle Files into Your Project:
The Particular Editor exports one or multiple particle layers. For each particle layer, it generates a configuration file (configs.json) and a related image file (texture.png). In the configuration file, there is a node named textureFileName, which refers to the image file. Place the image and configs.json file in your project's assets folder, and add the necessary assets entry in your pubspec.yaml file.

assets:
  - assets/configs.json
  - assets/texture.png

https://docs.flutter.dev/ui/assets/assets-and-images

To use this library, import package:particular/particular.dart.

final _particleController = ParticularController();
...
@override
void initState() {
  _loadParticleAssets();
  super.initState();
}

// Load configs and texture of particle
Future<void> _loadParticleAssets() async {

  // Load particle configs file
  String json = await rootBundle.loadString("assets/configs.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
  );
}

III. Add the Particular widget in your widget three:

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

IIII. Live Update Particle Layer:

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

You can also use different image types supported by Flutter, with varying names and locations, following the guidelines below:

{
  "textureFileName": "images/particle_snow.webp"
}

assets:
  - assets/data/particle_snow.json
  - assets/images/particle_snow.webp

...

// Load particle configs file
String json = await rootBundle.loadString("assets/data/particle_snow.json");

...
