Description:

dart native compression

dart_native_compression #
#
LZ4 #
The lz4 in this library is a ffi binding to lz4 v1.9.3, the compressed block and frame format are both interoperable with official C api, as well as other interoperable ports, bindings and CLI tools.
Getting Started
import 'dart:ffi';
import 'package:dart_native_compression/dart_native_compression.dart';

final lz4 = Lz4Lib(lib: DynamicLibrary.open('libnative_compression.so'));
print('LZ4 version number: ${lz4.getVersioinNumber()}');

To compress data into a lz4 frame
final compressedFrame = lz4.compressFrame(data);

To decompress a lz4 frame with a single function
final decompressed = lz4.decompressFrame(compressedFrame);
copied to clipboard
To decompress a lz4 frame with stream api
await for (final decompressedChunk
in lz4.decompressFrameStream(compressedStream)) {
// Your logic here
}
