TapParticle class

A TapParticle display particles when push button. If syncAnimation is set, display particles according to it.

{@tool snippet} This example shows how to create the button that can display particle.

final controller = AnimationController(
vsync: this,
duration: Duration(milliseconds: 300),
lowerBound: 0.0,
upperBound: 1.0,
);
TapParticle(
size: 50,
particleCount: 5,
color: Colors.red,
syncAnimation: controller,
duration: const Duration(milliseconds: 500),
child: TapFillIcon(
  animationController: controller,
  borderIcon: const Icon(
    Icons.star_border,
    color: Colors.grey,
    size: 50,
  ),
  fillIcon: const Icon(
    Icons.star,
    color: Colors.yellow,
    size: 50,
  ),
  initialPushed: false,
  ),
),

Properties

child → Widget?
The widget in the center of a particle.
final
color → Color
The color of particles.
final
controller → AnimationController?
The animation controller for controlling the particle animation.
final
duration → Duration
The animation's duration.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
particleCount → int
The number of particle lines. The particles display in a circle.
final
particleLength → double?
The maximum length of a particle. Particles are to this length when the animation value is just half.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
size → double
The size of child in this object. It display empty space of the size.
final
syncAnimation → AnimationController?
The Animation for synchronizing the particle animation. The particle animation is starting when syncAnimation called forward method. If syncAnimation called reverse method, the particle animation reset animation.
