A Flutter widget that shoots confetti all over the screen.
Blast some confetti all over the screen and celebrate user achievements!
A video walkthrough is available here.
To use this plugin, add
confettias a dependency in your pubspec.yaml file.
See the example to get started quickly.
To begin you need to instantiate a
ConfettiControllervariable and pass in a
ConfettiControllercan be instantiated in the
initStatemethod and disposed in the
buildmethod return a
ConfettiWidget. The only attribute that is required is the
Other attributes that can be set are: *
blastDirectionality-> an enum value to state if the particles shoot in random directions or a specific direction.
BlastDirectionality.explosivewill shoot in random directions and don't require a
blastDirectionto be set.
blastDirectionto specify the direction of the confetti. *
blastDirection-> a radial value to determine the direction of the particle emission. The default is set to
PI(180 degrees). A value of
PIwill 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
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
maxBlastForceis set to
minBlastForce-> will determine the minimum blast force applied to a particle within it's first 5 frames of life. The default
minBlastForceis set to
truea 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
controlling the minimum possible size of the confetti. To be used in conjuction withmaximumSize
. For example, setting aminimumSize
will ensure that the confetti will never be smaller than the specified size. Must be positive and smaller than themaximumSize
. Can not be null. *maximumSize
controlling the maximum possible size of the confetti. To be used in conjuction withminimumSize
. For example, setting amaximumSize
will create confetti with a size somewhere between the minimum and maximum size of (100, 100) [widht, height]. Must be positive and bigger than theminimumSize
, Can not be null. *gravity
-> change the speed at which the confetti falls. A value between 0 and 1. The higher the value the faster it will fall. Default is set to0.1
-> configure the drag force to apply to the confetti. A value between 0 and 1. A value of 1 will be no drag at all, while 0.1, for example, will be a lot of drag. Default is set to0.05
*canvas` -> set the size of the area where the confetti will be shown, by default this is set to full screen size.
Enjoy the confetti.
NOTE: Don't be greedy with the number of particles. The more particles that are on screen the more calculations need to be performed. Performance improvements have been made, however this is still ongoing work. Too many particles will result in performance issues. Use wisely and carefully.
