Overview
Perfect Freehand is a Dart package that enables pressure-sensitive freehand drawing by converting input points into smooth, accurate polygon outlines. It enhances digital sketching and signature capture by simulating natural pen strokes with precise control over line thickness and shape. Ideal for applications requiring expressive, fluid drawing such as art tools, note-taking apps, or electronic signatures. The package supports multiple platforms including mobile, web, and desktop, ensuring consistent performance across devices.
