ParticlesCanvas

Particle dissipating effect created using Flutter, FlutterFlow, and some math!

Try out the DEMO! (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)

The ParticleCanvas is a FlutterFlow Custom Widget, 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:

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<ParticleCanvas> createState() => _ParticleCanvasState();
}
