Intl Utils

Dart package that creates a binding between your translations from .arb files and your Flutter app. It generates boilerplate code for official Dart Intl library and adds auto-complete for keys in Dart code.


You can use this package directly (i.e. for Continuous Integration tools or via CLI) or leave it to Visual Studio Code or IntelliJ/Android Studio plugins to run it automatically whenever you modify ARB files.

Follow these steps to get started:

Configure package

Add package configuration to your pubspec.yaml file. Here is a full configuration for the package:

  enabled: true # Required. Must be set to true to activate the package. Default: false
  class_name: S # Optional. Sets the name for the generated localization class. Default: S
  main_locale: en # Optional. Sets the main locale used for generating localization files. Provided value should consist of language code and optional script and country codes separated with underscore (e.g. 'en', 'en_GB', 'zh_Hans', 'zh_Hans_CN'). Default: en

Add ARB files

Add one ARB file for each locale you need to support in your Flutter app. Add them to lib/l10n folder inside your project, and name them in a following way: intl_<LOCALE_ISO_CODE>.arb. For example: intl_en.arb or intl_en_GB.arb.

If you wonder how to format key-values content inside ARB files, here is detailed explanation.

Run command

To generate boilerplate code for localization, run the generate program inside directory where you pubspec.yaml file is located:

  pub run intl_utils:generate

This will produce files inside lib/generated directory.
