Overview
Poly is a Dart library designed to determine whether one or more points lie within a polygon. It provides efficient geometric calculations for point-in-polygon testing, useful in spatial data analysis, mapping applications, and interactive graphics. The library supports both simple and complex polygons, including those with holes. It is lightweight, easy to integrate via Flutter's package manager, and ideal for apps requiring real-time spatial queries. The source code is publicly available on GitHub for transparency and customization.
