WaveSticksLoader class

Widget de carga animado con efecto de onda gaussiana.

Crea un loader con múltiples barras (sticks) que se animan siguiendo una distribución gaussiana, creando un efecto de onda suave que se mueve de izquierda a derecha.

El parámetro waveWidth controla el ancho de la onda gaussiana, garantizando que la animación siempre sea suave: la onda comienza y termina fuera del área visible, asegurando que los sticks visibles siempre tengan transiciones naturales.

Perfecto para:

  • Estados de carga elegantes
  • Visualizadores de audio
  • Efectos de progreso creativos
  • Indicadores de actividad

Ejemplo básico:

WaveSticksLoader(
  size: Size(350, 100),
  duration: Duration(milliseconds: 1500),
  numberOfSticks: 10,
  stickWidth: 5,
  stickHeight: 30,
  middleWaveStickHeight: 45,
  stickSpacing: 8,
  stickColor: Colors.blue,
  waveWidth: 1.5,
)

Ejemplo de visualizador de audio:

WaveSticksLoader(
  size: Size(400, 120),
  numberOfSticks: 20,
  stickWidth: 4,
  stickHeight: 20,
  middleWaveStickHeight: 60,
  stickColor: Colors.orange,
  waveWidth: 2.0,
)
