Getting Started

To use this plugin, add confetti as a dependency in your pubspec.yaml file.

See the example to get started quickly.

To begin you need to instantiate a ConfettiController variable and pass in a Duration argument. The ConfettiController can be instantiated in the initState method and disposed in the dispose method.

In the build method return a ConfettiWidget. The only attribute that is required is the ConfettiController.

Other attributes that can be set are:

• blastDirection -> a radial value to determine the direction of the particle emission. The default is set to PI (180 degrees). A value of PI will emit to the left of the canvas/screen.
• emissionFrequency -> should be a value between 0 and 1. The higher the value the higher the likelihood that particles will be emitted on a single frame. Default is set to 0.02 (2% chance)
• numberOfParticles -> the number of particles to be emitted per emission. Default is set to 10
• shouldLoop -> determines if the emission will reset after the duration is completed, which will result in continues particles being emitted, and the animation looping
• maxBlastForce -> will determine the maximum blast force applied to a particle within it's first 5 frames of life. The default maxBlastForce is set to 20
• minBlastForce -> will determine the minimum blast force applied to a particle within it's first 5 frames of life. The default minBlastForce is set to 5
• displayTarget -> if true a crosshair will be displayed to show the location of the particle emitter
• colors -> a list of colors can be provided to manually set the confetti colors. If omitted then random colors will be used. A single color, for example [Colors.blue], or multiple colors [Colors.blue, Colors.red, Colors.green] can be provided as an argument in the `ConfettiWidget

Enjoy the confetti.

NOTE: Don't be greedy with the number of particles. Too many will result in performance issues. Future versions might be more performant. Use wisely and carefully.
