The Pulsator widget allows you to create pulsating animations with customizable styles. You can control the number of pulses, animation duration, repetition, and more. This widget is perfect for adding dynamic visual effects to specific areas of your app.

Pulsator(
  style: PulseStyle(color: Colors.blue),
  count: 5,
  duration: Duration(seconds: 4),

  startFromScratch: false,
  autoStart: true,
  fit: PulseFit.contain,
  child: YourContentWidget(),
)

`PulseIcon` Widget

The PulseIcon widget simplifies the process of displaying an icon with a pulsing effect. It allows you to customize the pulse and icon properties effortlessly.

PulseIcon(
  icon: Icons.favorite,
  pulseColor: Colors.red,

  iconSize: 44,
  innerSize: 54,
  pulseSize: 116,
  pulseCount: 4,
  pulseDuration: Duration(seconds: 4),
)

Features
