Migration Guide #

This is the initial release, so no migration is needed.

Known Limitations #

• Languages are limited to the 9 currently supported
• Error codes are predefined (no custom error codes yet)
• Translation context is service-based only

Future Roadmap #

• Additional language support (Japanese, Korean, Chinese)
• Custom error code support
• Integration with Flutter's Localizations
• Contextual error messages
• Error analytics and reporting
