Overview
opencv_dart provides OpenCV4 bindings for Flutter using dart:ffi, enabling computer vision and image processing capabilities in cross-platform applications. It allows developers to leverage OpenCV's extensive library of algorithms—such as image filtering, object detection, and feature extraction—directly within Flutter apps on Android, iOS, macOS, Windows, and Linux. The package bridges native OpenCV functionality with Dart code, offering high performance through direct system calls. Ideal for integrating real-time camera processing, OCR, or advanced image analysis into mobile and desktop apps.
