Getting Started

Welcome to Localization Pro, the dynamic localization solution for Flutter apps. This guide will help you integrate Localization Pro into your project effortlessly.

Step 1: Add the package to your project

First, you need to add Localization Pro to your project. Insert the following line into your pubspec.yaml under the dependencies section:

dependencies:
  localization_pro: ^x.y.z

Step 2: Install the package

After updating your pubspec.yaml, run the following command to install the package:

flutter pub get

This command fetches the package and installs it into your project.

Step 3: Import the package

Add the following import to the Dart files where you want to use the localization features:

import 'package:localization_pro/localization_provider.dart';

Usage

The Localization Pro package offers comprehensive localization functionalities. Below is a guide on how to utilize all features in your Flutter application.

Setting Up Locales and Translations

First, define the locales your application will support along with the corresponding translation files. Here's an example of how to set up supported locales and their translations:

List<SupportedLocale> supportedLocales = [
  SupportedLocale(
    locale: Locale('uz', 'UZ'),
    translations: [
      SupportedTranslation(name: 'home', path: 'assets/locales/uz_UZ/home.json'),
      SupportedTranslation(name: 'settings', path: 'assets/locales/uz_UZ/settings.json'),
    ]
  ),
  SupportedLocale(
    locale: Locale('en', 'US'),
    translations: [
      SupportedTranslation(name: 'home', path: 'assets/locales/en_US/home.json'),
      SupportedTranslation(name: 'settings', path: 'assets/locales/en_US/settings.json'),
    ]
  )
];

Ensure your JSON translation files are structured properly and stored at the specified paths.

Initialization in Main

void main(){
// Initialize the LocalizationManager
  LocalizationManager locManager = LocalizationManager(
    supportedLocales: supportedLocales,
    initialLocale: Locale('uz', 'UZ'),
    initialTranslations: ['home'],
    debugMode: true  // Toggle this based on your environment
  );

  // Run the app and wrap MyApp with LocalizationProvider
  runApp(LocalizationProvider(
    localizationManager: locManager,
    child: MyApp()
  ));
}

Dynamic Translation Management

To dynamically add or remove translations during runtime, you can use methods provided by the LocalizationManager through the context. For instance:

Adding a Translation

context.addTranslation('settings');

This would load the 'settings' translation for the current locale.

Removing a Translation

context.removeTranslation('settings');

This would unload the 'settings' translation from the current locale.

Changing Locale

Change the application's locale dynamically and reload the necessary translations:

context.changeLocale(Locale('es', 'ES'));

This switches the application's locale to Spanish and loads the appropriate translations.

Translating Strings

Extend the String class to use translations easily in your UI code:

Text('home_title'.tr())

Translation with Parameters:

Suppose you have a translation entry that expects a name and a date. The JSON might look like this:

{
  "greeting": "Hello, {name}! Today is {date}."
}

Using trParams in Code:

You can use the trParams method to insert dynamic values into this translation:

String greeting = 'greeting'.trParams({
  'name': 'Alice',
  'date': 'April 4th'
});
Text(greeting); // Displays: "Hello, Alice! Today is April 4th."

Documentation for Handling Nested JSON Translations

Purpose:

Handling nested JSON structures allows your localization system to manage complex translation entries organized in a hierarchical manner.

Usage:

Nested JSON Example:

Your JSON file might contain nested keys like so:

{
  "settings": {
    "audio": {
      "volume": "Volume",
      "balance": "Balance"
    },
    "display": {
      "brightness": "Brightness",
      "contrast": "Contrast"
    }
  }
}

Fetching a Nested Translation:

Access the nested translation using dot notation:

Text('settings.audio.volume'.tr()); // Displays: "Volume"
