RotatingArcLoader class

RotatingArcLoader is a custom loader widget that displays a rotating arc animation.

This loader uses an arc with two colors and rotates it indefinitely. It can be customized with different colors, sizes, stroke widths, and animation duration.

Parameters:

  • size : double - Specifies the size (width and height) of the loader widget.

  • primaryColor : Color - The main color of the loader's arc.

  • secondaryColor : Color - The secondary color for the remaining portion of the arc.

  • strokeWidth : double - The thickness of the loader arc.

  • duration : int - The animation duration in milliseconds, determining the rotation speed.

Assertions:

  • The loader's size must be greater than 0,
  • The stroke width must be positive and less than size/12,
  • The duration must be more than 1000 milliseconds.

Example:

RotatingArcLoader(
  size: 48,
  primaryColor: Colors.white,
  secondaryColor: Colors.red,
  strokeWidth: 5,
  duration: 1000,
)
