Translate AppFlowy

We'd like AppFlowy to be usable by people from all over the globe. You can help us reach that goal by contributing to our translation efforts. See below on how to fill out missing translations, modify existing translations, or add a language that isn't supported yet.

Modify an Already-Supported Language

Using the inlang no-code editor

  1. 1.
    Open the inlang-editor
  2. 2.
    Edit translations (filter & search can help)
  3. 3.
    Run flutter pub run easy_localization:generate -S assets/translations/
  4. 4.
    Run flutter pub run easy_localization:generate -f keys -o locale_keys.g.dart -S assets/translations
  5. 5.
    Verify that the translation has changed appropriately by compiling and running the app.

Directly in the source code

  1. 1.
    Modify the specific translation file located at: frontend/appflowy_flutter/assets/translations/<language-code>-<country_code>.json
  2. 2.
    Run flutter pub run easy_localization:generate -S assets/translations/
  3. 3.
    Run flutter pub run easy_localization:generate -f keys -o locale_keys.g.dart -S assets/translations
  4. 4.
    Verify that the translation has changed appropriately by compiling and running the app.

Add an Unsupported Language

Adding new languages from within the inlang editor is not supported yet, but you can add the language and then do the translations in inlang. (Adding via inlang is coming soon)
  1. 1.
    Create a JSON file that contains the translation tokens and values. You can simply copy frontend/appflowy_flutter/assets/translations/en.json and edit it from there.
  2. 2.
    The name of the file should be <language_code>-<country_code>.json, where language_code follows the ISO-639-1 standard and the country_code is a valid ISO3166 alpha2 country code. For example, Spanish in Venezuela would be es-VE.json. If the language doesn't change much between countries that use it, you can simply use the language code instead, e.g. pl.json.
  3. 3.
    Run the following commands from frontend/appflowy_flutter:
    flutter pub run easy_localization:generate -S assets/translations/
    flutter pub run easy_localization:generate -f keys -o locale_keys.g.dart -S assets/translations -s en.json
  4. 4.
    Alternatively, run the AF: Generate Language Task from VSCode by hitting F1, selecting Tasks: Run Task, then searching for the task.
  5. 5.
    In frontend/appflowy_flutter/lib/startup/tasks/app_widget.dart, search for the InitAppWidgetTask class and add the new language (e.g. Locale('en', 'IN')) to the supportedLocales list :
    runApp(
    EasyLocalization(
    supportedLocales: const [
    Locale('am', 'ET'),
    Locale('ar', 'SA'),
    Locale('ca', 'ES'),
    Locale('de', 'DE'),
    Locale('en'),
    ... // <---- Add locale to this list
    ],
    path: 'assets/translations',
    fallbackLocale: const Locale('en'),
    child: app),
    );
  6. 6.
    Add the name of the language in that language to the list of language names in frontend/appflowy_flutter/packages/flowy_infra/lib/language.dart.
    String languageFromLocale(Locale locale) {
    switch (locale.languageCode) {
    case "en":
    return "English";
    case "zh":
    return "简体中文";
    case "de":
    return "Deutsch";
    case "es":
    return "Español";
    case "fr":
    return "Français";
    ... // <- add your language here.
    default:
    return locale.languageCode;
    }
    }

How to test your changes

Once you are pleased with your translations, compile AppFlowy, select the language and see your work come to life! If everything is working fine, don't forget to create a PR on Github so that others can also benefit from your effort.
Change your language in the settings page of AppFlowy
