Overview
BlurHash Dart is a pure Dart implementation of the BlurHash algorithm, enabling efficient generation and decoding of compact image placeholders. It provides encoder and decoder functionality along with useful utility extensions for seamless integration into Flutter applications. Ideal for displaying low-bandwidth previews of images during loading, it supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux. The package is lightweight and designed for performance without external dependencies.
Use cases
- Generating image placeholders during loading
- Creating low-resolution previews for large images
