Overview
The image_compare package is a Dart utility for comparing images to detect differences using multiple algorithms. It enables developers to assess visual discrepancies between two images, useful for testing UI consistency, validating image transformations, or detecting changes in screenshots. The package supports cross-platform use on Android, iOS, macOS, Windows, and Linux, making it ideal for automated testing workflows. It provides a simple API to integrate image comparison logic into Flutter applications.
