Installation

Add this to your pubspec.yaml:

dependencies:
  sber_id: ^0.0.1+1

iOS Setup

1. Minimum iOS Version

Ensure your iOS deployment target is 14.0+ in ios/Podfile:

platform :ios, '14.0'

2. Configure URL Scheme

Step 2.1: Choose your URL scheme

Your redirectUri should follow this format: yourapp://auth

Examples:

• App name "MyStore" → mystore://auth
• App name "ShopApp" → shopapp://auth

Step 2.2: Add URL Scheme to Info.plist

Replace yourapp with your chosen scheme:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLName</key>
        <string>com.example.app</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>yourapp</string> <!-- Replace with your scheme (e.g., mystore, mango) -->
        </array>
    </dict>
</array>

For example for Mango app:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLName</key>
        <string>com.mango.app</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>mango</string>
        </array>
    </dict>
</array>

3. Register redirectUri with Sber ID

⚠️ Important: You must register your redirectUri with Sber ID:

Contact Sber ID support (support@ecom.sberbank.ru) to register your clientId and redirectUri before using in production.

4. Add LSApplicationQueriesSchemes

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>sberbankidexternallogin</string>
    <string>sbolidexternallogin</string>
    <string>btripsexpenses</string>
    <string>ios-app-smartonline</string>
    <string>sberid</string>
    <string>sberbankid</string>
</array>

5. Add NSAppTransportSecurity

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>id.sber.ru</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
    </dict>
</dict>

Usage

import 'package:sber_id/sber_id.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  // Initialize with your credentials
  await SBerId.instance.initialize(
    SBerIdConfig(
      clientId: 'your-client-id',           // From Sber ID developer portal
      redirectUri: 'yourapp://auth',        // Must match Info.plist URL scheme
      partnerName: 'Your App Name',         // Your app name
    ),
  );

  runApp(MyApp());
}

// Rest of the example code...

Configuration

Required Parameters

Parameter	Description	Example
clientId	Your client ID from Sber ID developer portal	'abc123-def456-ghi789'
redirectUri	Your app's custom URL scheme (must be registered with Sber ID)	'myapp://auth'
partnerName	Your company or application name	'My Company'

URL Scheme Matching

Make sure your configuration matches:

In your Dart code:

redirectUri: 'mango://auth'

In Info.plist:

<string>mango</string>  <!-- Same scheme name -->

Troubleshooting

Common Issues

1. "Invalid redirect URI" error

   • Ensure redirectUri is registered with Sber ID
   • Check URL scheme matches Info.plist exactly

2. App doesn't open after authentication

   • Verify URL scheme in Info.plist
   • Check CFBundleURLSchemes array

3. "Sber ID app not found" error

   • Add all required schemes to LSApplicationQueriesSchemes
