flutter_barcode_sdk

flutter_barcode_sdk

A cross-platform Flutter plugin for barcode reading and scanning, powered by the Dynamsoft Barcode Reader SDK. Supports Android, iOS, Web, Windows, and Linux.

Repository Structure

This is a monorepo for the flutter_barcode_sdk federated plugin, following the Flutter camera package pattern. All packages are siblings under packages/ and are published to pub.dev independently:

Package	Description
flutter_barcode_sdk	App-facing package. Add this to your app.
flutter_barcode_sdk_platform_interface	Platform interface contract and shared data models.
flutter_barcode_sdk_android	Android implementation.
flutter_barcode_sdk_macos	macOS implementation (universal-2).
flutter_barcode_sdk_windows	Windows implementation.
flutter_barcode_sdk_linux	Linux implementation.
flutter_barcode_sdk_web	Web implementation with a self-hosted JS/WASM bundle — no CDN <script> tag needed.

The platform packages are endorsed by the app-facing package, so app developers only need to depend on flutter_barcode_sdk.

Related Packages

• flutter_capture_vision — same six-platform architecture, plus MRZ (passport/ID) recognition and document boundary detection.
• flutter_lite_camera — lightweight camera preview and frame capture on all six platforms; the bundled example apps use it as the frame source for live scanning.

Development

The repository uses a pub workspace — run flutter pub get once at the repository root and all packages resolve local dependencies automatically.

flutter pub get        # once at the repo root
flutter analyze        # per package: cd packages/<pkg> && flutter analyze
flutter test

Each package has its own example/ app for standalone testing:

cd packages/flutter_barcode_sdk_windows/example
flutter run -d windows

# macOS (requires Xcode + CocoaPods, macOS 12+)
cd packages/flutter_barcode_sdk_macos/example
flutter run -d macos

Publishing

Each package is published independently from its own directory, with its own version:

cd packages/flutter_barcode_sdk_web
dart pub publish       # dry run: dart pub publish --dry-run

The GitHub Actions workflow .github/workflows/publish.yml publishes automatically when a tag of the form <package-name>-v<version> is pushed, e.g. flutter_barcode_sdk_web-v1.2.3, or manually via Actions → Publish to pub.dev → Run workflow.

Because each platform package ships its own native binaries, each package gets the full 100 MB pub.dev size limit independently.
