When adding new strings to be localized, update intl_en_US.arb, which
is used by this project as the template. When creating new entries, they
have to be in the following format:
"dartGetterVariableName": "english translation of the message",
"@dartGetterVariableName": {
"description": "description that the localizations delegate will use."
},
In this example, dartGetterVariableName should be the Dart method/property
name that you will be using in your localizations delegate.
After adding the new message in intl_en_US.arb, it can be used in the app by
regenerating the GalleryLocalizations delegate and the messages_*.dart files.
This allows use of the English message through your localizations delegate in
the application code immediately without having to wait for the translations
to be completed.
How to Generate GalleryLocalizations with Grinder
From the samples/gallery/ directory:
Make sure you have grinder installed by
running flutter pub get.
Then run flutter pub run grinder l10n to generate GalleryLocalizations.
For more details on what flutter pub run grinder l10n runs, you can read below
under How to Generate GalleryLocalizations with l10n scripts. The current
supported locales list is sorted alphabetically. This means that after running
the script, you have to update gallery_localizations.dart and move the en_US
locale to the top of the list.
How to Generate GalleryLocalizations with l10n scripts
To generate GalleryLocalizations, from samples/gallery/ run:
From samples/gallery/, run dart tool/l10n_cli/main.dart, which
will generate intl_en_US.xml. This will be used by the internal translation
console to generate messages in the different locales.
Run the formatter to make the Flutter analyzer happy:
flutter format .
Generating New Locale Arb Files
Use the internal tool to create the intl_<locale>.arb files once the
translations are ready.
Generating Flutter Localization Files
If new translations are ready and the intl_<locale>.arb files are already
available, run the following commands to generate all necessary
messages_<locale>.dart files and the localizations_delegate.dart file:
