Particle class

The Particle class represents a single particle in the animation.

The Particle class holds information about the particle's configuration, position, size, and appearance. It is responsible for drawing the particle on the canvas using the provided configuration and applying any transformations specified by the rotation.

Constructors

Particle({required ParticleConfiguration configuration, required Offset position, double rotation = 0})
Creates a Particle with the specified configuration and position.

Properties

color → Color
The current color of the particle
no setter
hashCode → int
The hash code for this object.
no setterinherited
initialColor → ParticleColor
The initial color of the particle as defined in its configuration.
final
initialPosition → Offset
The initial position of the particle when it was created.
final
initialSize → Size
The initial size of the particle as defined in its configuration.
final
position ↔ Offset
The current position of the particle relative to the top left of the canvas.
getter/setter pair
postEffectBuilder → PostEffectBuilder?
Effect to trigger once particle travel is over.
final
rotation ↔ double

getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shape ↔ Shape
The shape of the particle as defined in its configuration.
latefinal
size ↔ Size
