✨ touch_fx

A Flutter package that adds dynamic touch-based particle effects — inspired by interactive visuals seen in games and creative apps.
When users drag their fingers across the screen, glowing animated triangles appear, move, fade, and react like sparks.

📱 Demo

🚀 Features

  • Interactive particle system using GestureDetector and CustomPainter
  • Randomized triangle size, velocity, color, and rotation
  • Automatically removes faded-out triangles for better performance
  • Fully customizable and extendable
