Localization

Priority: P1 (STANDARD)

Consistent multi-language support using easy_localization.

Structure

assets/
└── translations/
    ├── en.json
    └── vi.json

Implementation Guidelines

• Bootstrap: Wrap root with EasyLocalization. Always use await EasyLocalization.ensureInitialized().
• Format: Default to JSON. Store in assets/translations/.
• Lookup: Use .tr() extension on strings.
• Locale: Change via context.setLocale(Locale('code')).
• Params: Use {} in JSON; pass via tr(args: [...]).
• Counting: Use plural() for quantities.
• Sheets: Sync via sheet_loader_localization from Google Sheets for Online file storage to JSON/CSV.

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.
