套件介紹

根據套件公開資料產生的選型評估，僅供參考。

The zstandard_linux package provides a Linux-specific implementation of the Zstandard compression library for Flutter applications. It enables efficient, high-performance compression and decompression of data directly within Linux-based Flutter apps. Built for compatibility with the Zstandard algorithm, it offers fast speeds and strong compression ratios. The package is designed to integrate seamlessly into Flutter projects targeting Linux platforms, leveraging native C bindings for optimal performance. It supports common use cases involving file compression, data transmission, and storage optimization on Linux systems.

Zstandard

Zstandard (zstd) is a fast, high-compression algorithm developed by Meta (formerly Facebook) designed for real-time compression scenarios. It offers 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 widely used in data storage, transmission, and backup solutions.

This repository contains a federated Flutter plugin and a CLI package for zstandard compression, enabling both in-app and command-line usage. The two main components are:

zstandard: A Flutter plugin for cross-platform compression, supporting mobile, desktop, and web platforms. This package integrates the zstd library through FFI for native platforms and WebAssembly for the web, allowing efficient data compression in any Flutter environment.
zstandard_cli: A pure Dart package providing CLI capabilities for macOS, Windows, and Linux. It enables command-line compression and decompression for data files and streams.

Native platform packages and the CLI share the zstd C source and FFI bindings via the zstandard_native package (zstandard_native/src/zstd/). zstandard_native is published to pub.dev as part of this repo’s release set, so a single copy is used whether you depend on the plugin from the repo or from pub.dev.

Basic Usage

In-App (Flutter)

import 'package:zstandard/zstandard.dart';

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

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

  Uint8List? compressed = await zstandard.compress(originalData, 3);
  
  final decompressed = compressed == null
      ? null
      : await zstandard.decompress(compressed, maxOutputSize: 64 * 1024 * 1024);
}

Using extensions:

import 'package:zstandard/zstandard.dart';

void main() async {
  Uint8List originalData = Uint8List.fromList([...]);

  Uint8List? compressed = await originalData.compress();
  
  final decompressed = await compressed.decompress(
    maxOutputSize: 64 * 1024 * 1024,
  );
}

Command Line (zstandard_cli)

# Compress a file with a specified compression level
dart run zstandard_cli:compress --level 3 myfile.txt

# Decompress a file
dart run zstandard_cli:decompress myfile.txt.zstd

Dart Code Example (CLI)

import 'package:zstandard_cli/zstandard_cli.dart';

void main() async {
  var cli = ZstandardCLI();

  final originalData = Uint8List.fromList([...]);

  final compressed = await cli.compress(originalData, compressionLevel: 3);

  final decompressed = await cli.decompress(compressed ?? Uint8List(0));
}

Using extensions in Dart:

import 'package:zstandard_cli/zstandard_cli.dart';

void main() async {
  final originalData = Uint8List.fromList([...]);

  final compressed = await originalData.compress(compressionLevel: 3);

  final decompressed = await compressed.decompress();
}
