Localization

Priority: P1 (HIGH)

Format Selection

  • CSV (Recommended for teams with translators): Google Sheets compatibility via sheet_loader_localization. Store in assets/langs/.
  • JSON (Developer-friendly): Nested structure support with IDE validation. Store in assets/translations/.

Scope Boundary

  • Use this skill for translation assets, EasyLocalization bootstrap, .tr(), plural(), and a language/locale switcher.
  • Do not use it for RTL-only widget direction, typography, or locale-aware date/number formatting when translation assets are unchanged.

Structure

# CSV Format (Google Sheets workflow)
assets/langs/langs.csv

# OR JSON Format (nested keys)
assets/translations/
├── en.json
└── vi.json

Implementation Workflow

  1. Initialize — Call await EasyLocalization.ensureInitialized() before runApp.
  2. Wrap root — Wrap app with EasyLocalization widget specifying supported locales and path.
  3. Translate strings — Use .tr() extension on keys (e.g., 'welcome'.tr()). For dynamic text, use 'welcome_user'.tr(namedArgs: {'name': 'John'}) with a {name} placeholder, or pass positional args:.
  4. Switch locale — Change via context.setLocale(Locale('vi')).
  5. Handle plurals — Use plural() for quantity-dependent strings, such as item_count or cart keys.
  6. Sync translations — Use sheet_loader_localization to auto-generate CSV/JSON from Google Sheets.

Bootstrap & Usage Examples

See implementation examples for bootstrap setup and translation usage patterns.

Anti-Patterns

  • No Hardcoded Strings: Always use translation keys from assets
  • No Manual Localization Calls: Use easy_localization .tr() extension
  • No Mismatched Keys: Ensure keys identical across all locale-specific files

Reference & Examples

For setup and Google Sheets automation: See references/REFERENCE.md.
