Flutter App Internationalization: An Easy Guide to Flutter Localization

Normally, the Localized apps have been widely downloaded by 128% higher than others. About 26% of revenue is increased for the business having the localized app. App localization involves the developers adding multiple languages to the applications. This caters to users who speak different languages. 

Flutter Localization Package provides the user with a better way to easily create the app. These also extensively support multiple languages. Internationalizing and localizing the Flutter app is quite important for gaining more audience.

Introduction: App Localization

App Localization involves the process of making the App completely adaptable for diverse people, linguistics and cultures. These can be easily achieved by providing a better ability for the user to easily use the app across different languages.

The process of making an app is quite different, and these are adaptable for the locales. This does not involve changing codes or even UI in the app. App localization in the modern day is not limited to the languages of a particular user.

• Generating Classes

Open pubspec.yaml

Replace # TODO: Add intl and flutter_localizations here. With:

intl: 0.16.1
flutter_localizations:
  sdk: flutter

Adding packages

Intl:

The Facilities for i18n as well as l10n are enabled, so this provides better message translation. It is also a suitable option for changing the date/number formatting or even parsing. It is quite a convenient option for dealing with various packages, even with generated classes.

flutter_localizations

Installing the flutter_localizations would be a much more secure option for enabling the feature-rich and user-friendly app.

• Choose the starter folder in the project directory
• Click Tools
• Click Flutter Intl
• Initialize for Project

• Command enabled can be added as the flutter_intl section for pubspec.yaml.

Add main_locale: en_US

flutter_intl: 

main_locale: en_US

  enabled: true

• Click “Pub” to get Flutter commands bar
• Click the Tools
• Open the Flutter Intl on IDE’s menu bar
• Click ‘Remove Locale’
• Choose ‘en’
• Click ‘OK’

Normally, the plugin created using the 2 folders will be added in the lib:

• Generated:

Enabled with generated classes

• l10n:

Home of.arbs

JSON syntax files hold your translations

You can extensively set Flutter Intl for configuring the app based on usage.

Benefits of Using Localize the App Using Flutter

In the modern day, there are more than 2 million apps that can be seen on the App store and Google Play Store. Competition in the business is also tougher with a plethora of apps.

It is quite a convenient option to leverage different strategies for generating revenue for the app. Common strategies involved are:

• In-app advertising
• Subscriptions to users
• In-app purchases

Increased Engagement

Localizing the Flutter web app also allows you to easily facilitate people across the world. Larger approach is a suitable option for gaining more engagements. Normally, the user also prefers to access apps providing better content tailored based on their preference and needs.

Methods to Localize a Flutter App

In the modern day, it is quite important to make the app visible to multiple locals. You also require localizing the apps. These help to extensively scale the audience level for maximum benefit. It provides better reach in driving the leads and traffic.

Step 1: Adding Dependencies

Installing the dependencies “pubspec.yaml” file is quite important for Flutter app localization. It is quite convenient for adding the ‘flutter_localizations’ as well as ‘intl’ packages in the Flutter project. You can also go to pubspec.yaml file even from the Flutter app with codes.

dependencies:
Flutter:
sdk: flutter 
flutter_localizations:
sdk: flutter
flutter:
generate: true

Step 2: Creating l10n.yaml file

Adding the dependencies includes a better way of creating the “l10.n.yaml” file. Using files enables localization classes, and you can generate the localization process. it is quite a convenient option for easily using these codes such as:

arb-dir: lib/l10n
template-arb-file: app_en.arb
output-localization-file: app_localizations.dart

The ‘arb-dir’ is enabled with the directory, so input files are found accordingly. You can also easily use the directory for adding message catalogs even without any hassle. Now you can use ‘template-arb-file’, which specifies the message with applications that support it. It is also enabled with the ‘output-localization-file’, giving you better stability in the main dart class file.

Step 3: Adding Template ARB Or Creating lib/l10n/app_en.arb file

Defining the path of the ARB file, especially with the l10n.yaml file, which allows you to create the template .arb file. It is a convenient option for adding this template to specific attributes. These are efficient options for creating .arb file templates in each language on the app supporting multiple languages.

{
"@@locale": "en",
 "helloWorld": "Hello World!",
 "@helloWorld": {
 "description": "The conventional newborn programmer greeting."
 }
}

Step 4: Integration of Localization Classes

You can integrate these localization classes using the Flutter app upon creating the template .arb file. Follow the code to automatically integrate localization classes.

import 'package:flutter/material.dart';
import 'package:flutter_gen/gen_l10n/app_localizations.dart'; // Add this
line.
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
// Add the `localizationsDelegate` and `supportedLocales` lines.
localizationsDelegates: AppLocalizations.localizationsDelegates,
supportedLocales: AppLocalizations.supportedLocales,
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
