Flutter plugin to implement Zstandard compression

Zstandard

Zstandard (zstd) is a fast, high-compression algorithm developed by Meta (formerly Facebook) designed for real-time compression scenarios. It provides a flexible range of compression levels, allowing both high-speed and high-ratio compression, making it ideal for applications with diverse performance needs. Zstandard is commonly used in data storage, transmission, and backup solutions.

This is a Flutter plugin that provides a pure implementation of the zstd compression algorithm, developed by Meta. It integrates the zstd library in C through FFI for native platforms, ensuring efficient compression and decompression. For web platforms, it leverages WebAssembly to deliver the same robust compression capabilities. This plugin enables seamless, cross-platform data compression, making it ideal for applications requiring high-speed and efficient data processing.

The C files to build the compression library come from the original facebook/zstd repository.

Usage

void act() async {
  final zstandard = Zstandard();

  Uint8List original = Uint8List.fromList([...]);

  Uint8List? compressed = await zstandard.compress(original);
  
  Uint8List? decompressed = await zstandard.decompress(compressed ?? Uint8List(0));
}

With extension functions:

void act() async {
  Uint8List original = Uint8List.fromList([...]);

  Uint8List? compressed = await original.compress();
  
  Uint8List? decompressed = await compressed.decompress();
}
