l10n_flutter

Description:

l10n flutter

Flutter Localization Framework. #
This single framework will help you localize your Flutter application without the headache. You can reorganize and rename keys in the contact variable as well as in local files without breaking the application. Later, when you run the builder, you'll get auto-generated locale output files for all supported locales.




Compile and test #
git clone https://github.com/dgofman/l10n_flutter.git

cd l10n_flutter

flutter create --org l10n_flutter -i objc -a java -t app .

flutter run -d chrome -t lib/examples/l10n_demo3_app.dart

Getting Started #
flutter create myapp

cd myapp
copied to clipboard

Add access to app resource directory in pubspec.yaml

dependencies:
flutter:
sdk: flutter

# Copy and paste
l10n_flutter: ^1.0.0
copied to clipboard

Create a locale model file - models/app_ln10.dart

import 'package:l10n_flutter/l10n_core.dart';

// Supported locales
const AppL10nSettings = L10nSettings(locales: [
L10nLocale('en', 'US', 'English, (US)'),
L10nLocale('en', 'GB', 'English (United Kingdom)'),
]);

@AppL10nSettings
class AppL10n {
static const truck = L10nSet('app_truck', 'Truck'); // where "app_truck" is the key in the locale file
}
copied to clipboard

Replace code in lib/main.dart

import 'package:flutter/material.dart';
import 'package:l10n_flutter/l10n_material_app.dart';
import './models/app_ln10.dart';

void main() => runApp(L10nMaterialApp(
locale: const Locale('en', 'GB'), // Set a default locale
supportedLocales: AppL10nSettings.supportedLocales, // Provide a list of supported locales
builder: (BuildContext context, Widget? child) => Scaffold(body: Text(AppL10n.truck.$)) // or AppL10n.truck.toString()
));

Note. These are the minimum requirements to run the application. However, your app is showing the default values as we are getting loading errors:

L10nLoader Error: Unable to load asset: l10n/en_GB.json

Generate Assets #

Create build.yaml file

builders:
l10n_builder:
import: "package:l10n_flutter/builder/builder.dart"
builder_factories: ["l10nBuilderFactory"]
build_extensions: {".dart:": [".json"]}
build_to: source

targets:
$default:
builders:
'l10n_flutter|l10n_builder':
enabled: true
generate_for: # the directory specified
- lib/models/app_ln10.dart
copied to clipboard

Include path to the locale output directory in pubspec.yaml

flutter:

# To add assets to your application, add an assets section, like this:
assets:
- assets/l10n/
copied to clipboard

Include the latest version of the build into dev dependencies https://pub.dev/packages/build_runner

dev_dependencies:
flutter_test:
sdk: flutter

build_runner: ^2.1.7
copied to clipboard

Generate files

flutter pub run build_runner build --delete-conflicting-outputs
copied to clipboard

Finally update content in assets/l10n/en_GB.json

{
"app_truck": "Lorry"
}
