Overview
The show_fps package is a lightweight Flutter tool that displays a real-time FPS (frames per second) badge in the corner of your app during development. It helps developers monitor performance and identify rendering bottlenecks by visualizing frame rate fluctuations. The badge is automatically hidden in release builds, ensuring it doesn't affect production apps. Compatible with all major platforms, including mobile, web, and desktop, it integrates seamlessly into any Flutter project with minimal setup. Ideal for optimizing UI responsiveness and detecting performance issues early in development.
