Localization

Priority: P1 (STANDARD)

Consistent multi-language support using easy_localization.

Format Selection

  • CSV (Recommended for teams with translators):
    • Non-technical editors can update easily
    • Native Google Sheets compatibility via sheet_loader_localization
    • Store in assets/langs/ (common convention)
  • JSON (Developer-friendly):
    • Nested structure support (e.g., items_count.zero)
    • IDE validation and autocomplete
    • Store in assets/translations/

Both formats work identically with easy_localization.

Structure

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

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

Implementation Guidelines

  • Bootstrap: Wrap root with EasyLocalization. Always use await EasyLocalization.ensureInitialized().
  • Lookup: Use .tr() extension on strings (e.g., 'welcome'.tr()).
  • Locale: Change via context.setLocale(Locale('code')).
  • Params: Use {} placeholders; pass via tr(args: [...]).
  • Counting: Use plural() for quantities.
  • Sheets Sync: Use sheet_loader_localization to auto-generate CSV/JSON from Google Sheets.

Anti-Patterns

  • Hardcoding: No raw strings in UI; use keys.
  • Manual L10n: Avoid standard Localizations.of; use GetX or easy_localization context methods.
  • Desync: Keep keys identical across all locale files.
