# ParticlesCanvas

Particle dissipating effect created using [Flutter](https://flutter.dev/), [FlutterFlow](https://flutterflow.io/), and some math!

> Try out the [**DEMO**](https://app.flutterflow.io/run/4JpKoK5qLbS3TuZpU0Fn)! *(But it's recommended to run it as a desktop or mobile app as it's not that optimized, so on web might be a little jarring)*

> 

> **FlutterFlow project:** https://app.flutterflow.io/project/particles-demo-vd2vhs

The `ParticleCanvas` is a FlutterFlow [Custom Widget](https://docs.flutterflow.io/customizing-your-app/custom-widgets), the color selector and the property editor are all built inside FlutterFlow.

## ParticleCanvas

This holds the logic for accepting user input for drawing on the canvas and particle dissipation effect. It accepts the following properties that you can customize:

``` dart

class ParticleCanvas extends StatefulWidget {

  const ParticleCanvas({

    Key? key,

    this.width,

    this.height,

    this.particleGroupRadius = 30.0,

    this.particleMaxSize = 6.0,

    this.effectDuration = 5.0,

    this.numberOfParticles = 12,

    this.gapBetweenDrawFraction = 0.5,

    this.particleColor = Colors.tealAccent,

  }) : super(key: key);

  final double? width;

  final double? height;

  final double particleGroupRadius;

  final double particleMaxSize;

  final double effectDuration;

  final int numberOfParticles;

  final double gapBetweenDrawFraction;

  final Color particleColor;

  @override

  State createState() => _ParticleCanvasState();

}

```
