📱 Flutter iOS Localization Setup for REL-ID IDV SDK

This document describes how to configure localization in a Flutter project (iOS platform) when integrating the REL-ID IDV SDK.

🏷️ Overview

REL-ID IDV Flutter plugins support localization for custom languages. By default, English is supported out-of-the-box via .strings files. Developers can add new languages and override SDK text by integrating localized string files provided by Uniken.

📂 String Files by Module

🔧 Integration Steps (iOS - Xcode)

Step 1: Get the .strings Files

Request default .strings files from Uniken for all modules you're integrating.

Step 2: Drag and Drop

Drag the string files (e.g., IDVCore.strings) into your Xcode project.

Step 3: Localize the File

• Select the added .strings file in the project navigator.
• Open the Identity Inspector.
• Click Localize to enable localization for the file.

Step 4: Add a New Language

• Go to Project > Info > Localizations.
• Enable Base Internationalization if not already.
• Click + to add a new language (e.g., French).

Step 5: Generate Localized Files

• Select the .strings file again.
• Choose the newly added language to generate a localized version (e.g., IDVCore.strings (French)).

Step 6: Translate and Customize

Override default English keys with the translated text in the new .strings file.

"SCAN_DOCUMENT_PROMPT" = "Veuillez scanner le document";
"CAPTURE_SELFIE_PROMPT" = "Veuillez capturer un selfie";

🔁 Repeat for Other Modules

Repeat steps 1–6 for:

• IDVDocumentCapture.strings
• IDVSelfieCapture.strings

This setup ensures a fully localized experience across all REL-ID SDK components in your Flutter iOS app.

🤖 Flutter Android Localization Setup for REL-ID IDV SDK

This guide outlines how to configure localization for the REL-ID IDV SDK in your Flutter app (Android platform).

🏷️ Overview

REL-ID IDV SDK supports multilingual translations through XML string resources. Developers can localize the SDK experience by adding or modifying string resources provided by Uniken for different modules.

📋 Prerequisites

Ensure you have the following files shared by the REL-ID admin:

• strings-idv.xml — For REL-ID Core module
• strings-idv-doc-scan.xml — For Document Capture module
• strings-idv-face-scan.xml — For Selfie Capture module

🛠️ Integration Steps

1. Open Android Studio

Open your Flutter Android project using Android Studio.

2. Create Resource Directory

• Navigate to res folder → right-click → New → Android Resource Directory.
• Set Resource type to values.
• Set Locale to your target language/region (e.g., ru-RU for Russian).

3. Add Localization Files

Copy the provided XML files into the newly created locale folder:

• values-ru-rRU/strings-idv.xml
• values-ru-rRU/strings-idv-doc-scan.xml
• values-ru-rRU/strings-idv-face-scan.xml

4. Translate the Values

Edit the XML files and override the string values with the appropriate translation:

<string name="scan_document_prompt">Пожалуйста, отсканируйте документ</string>
<string name="capture_selfie_prompt">Пожалуйста, сделайте селфи</string>

Repeat this for all supported strings.

📌 Notes

• If needed, you may merge these string files into your app’s strings.xml but retain all REL-ID key names.
• Repeat the above process for each target locale by creating new values-<locale> directories.

By following this guide, your Flutter Android application will deliver a seamless localized user experience for all REL-ID IDV SDK components.
