Overview
i69n is a lightweight internationalization package for Dart and Flutter that uses YAML files to manage translations and leverages source code generation for type-safe, compile-time checks. It simplifies localization by allowing developers to define language strings in structured YAML files and automatically generates Dart code for easy access. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, making it ideal for cross-platform apps requiring robust yet simple translation workflows.
Use cases
- Multi-language app support
- Static translation management
- Type-safe string access
- Cross-platform localization
- CI/CD integration
- Developer-friendly translation workflow
Key features
- YAML-based translation files

Suitable for
- Flutter projects needing simple i18n
- Teams managing translations via YAML
- Developers wanting compile-time safety
- Apps targeting multiple languages
- Projects with strict CI/CD pipelines
- Small to medium-sized localization needs
Considerations
