SquareMatrixLoader class

Widget de carga animado con matriz de cuadrados que se expanden y contraen.

Crea un loader con una cuadrícula de cuadrados que se animan siguiendo diferentes patrones direccionales, creando efectos visuales dinámicos y modernos mediante transformaciones de escala.

Los cuadrados se expanden y contraen en secuencia según la dirección especificada, utilizando una onda sinusoidal para crear transiciones suaves. Soporta 8 direcciones diferentes: vertical, horizontal y cuatro variantes diagonales.

Perfecto para:

  • Estados de carga modernos y elegantes
  • Indicadores de progreso creativos
  • Pantallas de splash animadas
  • Transiciones visuales atractivas

Ejemplo básico:

SquareMatrixLoader(
  numberOfSquares: 4,
  squareHeight: 40,
  duration: Duration(milliseconds: 1500),
  color: Colors.blue,
  direction: TraverseDirection.LEFT_UP_RIGHT_BOTTOM,
)

Ejemplo con efecto diagonal:

SquareMatrixLoader(
  numberOfSquares: 5,
  squareHeight: 35,
  duration: Duration(milliseconds: 1800),
  color: Colors.orange,
  direction: TraverseDirection.RIGHT_BOTTOM_LEFT_UP,
  curve: Curves.easeInOut,
)

Ejemplo con matriz grande:

SquareMatrixLoader(
  numberOfSquares: 6,
  squareHeight: 25,
  duration: Duration(milliseconds: 2000),
  color: Colors.purple,
  direction: TraverseDirection.UP_BOTTOM,
  curve: Curves.linear,
)
