Particles class

Inheritance

Constructors

Particles({Key? key, required List<Particle> particles, required double height, required double width, bool connectDots = false, Emitter? particleEmitter, ParticlePhysics? particlePhysics, BoundType boundType = BoundType.None, ParticleInteraction? interaction, List<BurstEmitter> burstEmitters = const [], void onParticleExpired(Particle particle)?})
Creates a widget that handles per-frame animation of particles.
const

Properties

boundType → BoundType
Define the boundary type for the engine, one of:
final
burstEmitters → List<BurstEmitter>
Burst emitters run alongside the main particle pool.
final
connectDots → bool
Toggle line connections between particles. Not recommended for performance reasons.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double
Define the boundary size for the particle engine.
final
interaction → ParticleInteraction?
Define the touch control interaction settings for the engine.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onParticleExpired → void Function(Particle particle)?
Called when a particle's lifetime expires, before it is respawned/recycled. Lets the caller swap out particle state (e.g. a new image) for reuse.
final
particleEmitter → Emitter?
Set emission options.
final
particlePhysics → ParticlePhysics?
Set physics options.
final
particles → List<Particle>
Set a list of pre-defined particles to be used by the particle engine.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
width → double
Define the boundary size for the particle engine.
final

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → _ParticlesState
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.

Operators

operator ==(Object other) → bool
The equality operator.
