What it does

Flutter Localization is an agent skill from HoangNguyen0403/agent-skills-standard. Add Flutter translation assets, locale initialization, localized strings, locale switching, and plurals with easylocalization and CSV or JSON files. Use for Flutter i18n work; not RTL-only layout or locale-specific date formatting.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/REFERENCE.md` and `references/implementation.md`).

It sits in Mobile, covering Internationalization, Cross-platform mobile apps and Translation. It works with Flutter and Google Sheets. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Flutter i18n work
  • Not RTL-only layout
  • Locale-specific date formatting

Example prompts

  • “/flutter-localization”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  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'…
  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.

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flutter Localization loads about 640 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 63 tokens; SKILL.md has 199 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~640
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

flutter-localization
description
Add Flutter translation assets, locale initialization, localized strings, locale switching, and plurals with easy_localization and CSV or JSON files. Use for Flutter i18n work; not RTL-only layout or locale-specific date formatting.

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

text
# 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.
