Overview
ProgressiveImage is a Flutter widget that enhances image loading performance by displaying a low-quality placeholder image first, which gradually improves in quality as the full-resolution image loads. This technique reduces perceived load time and improves user experience, especially on slower networks. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, making it versatile for cross-platform applications. It integrates seamlessly with existing image loading workflows and works well with popular image providers like NetworkImage.
