💡 This Skill includes references (resource) components.

What problem does it solve?

Flutter apps often ship without localization, making it hard to reach multilingual users. This guide provides a complete approach to add internationalization using gen-l10n and the intl package, manage translations, and format locale-specific content.

Core Features & Use Cases

  • Setup and configuration for flutter_localizations, gen-l10n, and ARB workflow.
  • Message management, translation workflows, and locale-aware formatting for numbers and dates.
  • Use Case: Internationalize a chat app to support English, Spanish, and Chinese users with proper translations and locale formatting.

Quick Start

Create a new Flutter project, enable gen-l10n, add ARB files under lib/l10n, and wire LocalizationsDelegates in MaterialApp.

FAQPage Schema
How do I add internationalization to a Flutter app using gen-l10n?▼

To add internationalization to a Flutter app, integrate gen-l10n by enabling flutter_localizations, adding ARB files under lib/l10n, and wiring LocalizationsDelegates in MaterialApp. This setup enables multi-language user interfaces and translation management.

What is the best way to manage multilanguage translations in Flutter with ARB files?▼

Managing multilanguage translations in Flutter relies on the ARB workflow with gen-l10n. You create ARB files for each locale under lib/l10n, which the intl package then processes to generate localization classes for your app's UI.

Does Flutter intl package support locale-aware formatting for numbers and dates?▼

Yes, the Flutter intl package supports locale-aware formatting for numbers and dates. By integrating intl with your localization setup, you ensure numbers and dates display correctly according to the user's selected locale conventions.

How do I configure Flutter pubspec.yaml for multi-language UI support?▼

To configure Flutter for multi-language UI support, update pubspec.yaml to include flutter_localizations and enable the gen-l10n tool. This configuration activates the ARB workflow and LocalizationsDelegates required for multilanguage interfaces.

When do I need ARB files for Flutter localization?▼

You need ARB files for Flutter localization when setting up multi-language interfaces with gen-l10n. These ARB files store your translated messages and locale-specific resources, which gen-l10n uses to generate the Dart code for your app.

Can I use Flutter gen-l10n to support English, Spanish, and Chinese users simultaneously?▼

Yes, you can use Flutter gen-l10n to support English, Spanish, and Chinese users simultaneously. By creating dedicated ARB files for each locale, gen-l10n generates the necessary code to switch languages and format content per region.
