🎉 Third anniversary and new major release!

NEW FEATURES

• L10N values are now provided in sentence case!
• Tree-shakable via dart define flags.
• Optimized memory usage with lazy locale initialization - translations are now loaded on-demand instead of all at once.
• Reduced initial memory footprint by ~90% - only requested locales are instantiated.
• Added availableLocales getter to query all supported locales without materializing them.
• Single-use design: Mapper instances automatically free memory after localize() is called and cannot be reused. This ensures optimal memory efficiency - create a new instance if you need to localize again.

BREAKING CHANGES

• Single-use design: Mapper instances automatically free memory after localize() is called and cannot be reused. This ensures optimal memory efficiency - create a new instance if you need to localize again.

Previously, localized strings were provided in mixed lowercase (e.g., "islas Malvinas", in Spanish for FLK code) and sentence case. They are now unified and provided in sentence case only (e.g., "Islas Malvinas", in Spanish for FLK code) to preserve capitalization context for proper nouns and ensure immediate compatibility with independent UI labels.

Justification: Capitalization is context-sensitive and cannot be reliably reconstructed from lowercase source strings. By providing values in sentence case, we ensure high-fidelity data for headers and labels. This was also part of discussion in the past.

Migration:

• If you use these values as standalone labels, no action is required (you can also remove your formatter callback, if not needed).
• If you require mid-sentence (inline) text, use the formatter callback to strictly adapt the casing, rather than relying on direct string manipulation.

final localized = mapper.localize(
  isoCodes,
  mainLocale: locale,
  formatter: (_, l10n) => l10n.toLowerCase(), // <-- e.g., inline usage
);
