Flux Borders

A high-performance Flutter package for creating stunning, animated, and customizable borders using Fragment Shaders (GLSL).

Flux Borders allows you to add unique visual effects to your Flutter widgets with minimal performance impact, thanks to hardware-accelerated shaders.

Features

• High Performance: Uses Fragment Shaders (.frag) for smooth animations (60 FPS+).
• Diverse Effects: Includes 13+ unique border types ranging from classic Neon to complex effects like Fire, Liquid, and Circuit.
• Highly Customizable: Adjust colors, speeds, widths, spacing, and more.
• Global Parameters:
  • Glow: Add a beautiful outer glow to any border.
  • Speed: Control animation speed and direction (positive for clockwise, negative for counter-clockwise, 0 for static).
  • Responsive: Automatically adapts to widget size and border radius.
