zstandard_native

Native zstd C sources and FFI bindings used by the zstandard Flutter plugin platform implementations (Android, iOS, macOS, Linux, Windows) and CLI.

Contents

• src/zstd/ — C source code from facebook/zstd (common, compress, decompress).
• lib/zstandard_native_bindings.dart — FFI bindings generated from zstd.h for use by all platform plugins.

Usage

This package is a dependency of the platform-specific zstandard plugins. End users depend on zstandard (or individual platform packages); they do not need to depend on zstandard_native directly.

Development (monorepo)

From the repository root, the main example app uses dependency_overrides in zstandard/example/pubspec.yaml so that all packages (including zstandard_native) resolve from path. Run flutter pub get and builds from the example. When publishing to pub.dev, publish zstandard_native first, then the platform packages and the main plugin (they depend on zstandard_native: ^1.4.0).

Regenerating bindings

From this package directory:

dart run ffigen --config ffigen.yaml

Or from the repo root:

./scripts/regenerate_bindings.sh

Updating zstd sources

From the repository root:

./scripts/update_zstd.sh

This updates zstandard_native/src/zstd/ from the official facebook/zstd repository.
