Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
init(
) → void - Initializes the particle effect by resetting all the particles and assigning a random color from the palette.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
resetParticle(
int i) → Particle - Resets a particle's values.
-
setPalette(
Palette palette) → void - Sets the palette used for coloring.
-
setParticleCount(
int count) → void -
setParticleSize(
double min, double max) → void -
setShape(
ParticleShapeType shape) → void -
setSize(
Size size) → void - Sets the canvas size and updates dependent values.
-
setVelocity(
double vx, double vy) → void -
tick(
Duration duration) → void -
toString(
) → String -
A string representation of this object.
