yaml_localizations
A minimal YAML localization package for Flutter.
YAML is a human-readable, configuration file format with a minimal syntax, which allows you to represent strings as key/value pairs.
Usage
See example.
Install
Add to your pubspec.yaml
dependencies:
yaml_localizations:
Add a YAML file per language
Add a YAML file per language you support in an asset path
and describe it in your pubspec.yaml
flutter:
assets:
- assets/yaml_translations/
The YAML file name must match exactly the combination of language and country
code described in supportedLocales
.
That is Locale('en', 'US')
must have a corresponding assetPath/en-US.yaml
file.
Example YAML file
Hi: Hi
Text: |
There once was a tall man from Ealing
Who got on a bus to Darjeeling
It said on the door
"Please don't sit on the floor"
So he carefully sat on the ceiling
Long: >
Wrapped text
will be folded
into a single
paragraph
Blank lines denote
paragraph breaks
Tip: Yaml supports several ways of expressing strings. Use the vertical bar character to indicate that a string will span several lines. Use the greater-than character to break up long lines.
MaterialApp
Add YamlLocalizationsDelegate
to MaterialApp
and set supportedLocales
using language/country codes.
MaterialApp(
localizationsDelegates: [
... // global delegates
YamlLocalizationsDelegate('assets/yaml_translations'),
],
supportedLocales: [
Locale('en', 'GB'),
Locale('en', 'US'),
Locale('en'),
Locale('nb'),
],
}
API
Translate strings using
YamlLocalizations.of(context)?.string('Hi')
We keep the API simple, but you can easily add an extension method to String
like this:
extension LocalizedString on String {
String tr(BuildContext context) => YamlLocalizations.of(context)!.string(this);
}
Note on iOS
Add supported languages to ios/Runner/Info.plist
as described
here.
Example:
<key>CFBundleLocalizations</key>
<array>
<string>en-GB</string>
<string>en</string>
<string>nb</string>
</array>
