iOS Android License: MIT

Flutter plugin for the SEON Orchestration SDK, providing identity verification flows for iOS and Android. Built using Flutter’s MethodChannel for communication between Dart and native code.

Features

  • Cross-platform — One Dart API on iOS and Android
  • MethodChannel — Standard Flutter platform channel integration
  • Typed API — Dart classes and enums for configuration and results

Installation

Add the dependency to your pubspec.yaml:

dependencies:
  seon_orchestration_flutter: ^1.0.3   # use pub.dev once published

For a local checkout during development:

dependencies:
  seon_orchestration_flutter:
    path: ../seon-orchestration-flutter

For iOS, install CocoaPods dependencies:

cd ios && pod install

Quick start

import 'package:seon_orchestration_flutter/seon_orchestration_flutter.dart';

// 1. Initialize the SDK
await SeonOrchestration.initialize(const SeonConfig(
  baseUrl: 'https://your-api-endpoint.com',
  token: 'your-auth-token',
  language: 'en', // optional
));

// 2. Start the verification flow
final result = await SeonOrchestration.startVerification();

switch (result.status) {
  case SeonVerificationStatus.completedSuccess:
    print('Verification passed!');
    break;
  case SeonVerificationStatus.completedFailed:
    print('Verification failed.');
    break;
  case SeonVerificationStatus.interruptedByUser:
    print('User cancelled.');
    break;
  case SeonVerificationStatus.error:
    print('Error: ${result.errorMessage}');
    break;
  default:
    break;
}

Custom theme

The theme parameter is a Map<String, dynamic> that is JSON-encoded for the native SDK. See the SEON Orchestration Flutter SDK repository for theme and API details.

await SeonOrchestration.initialize(SeonConfig(
  baseUrl: 'https://your-api-endpoint.com',
  token: 'your-auth-token',
  language: 'en',
  theme: { /* your theme config */ },
));

Cleanup

await SeonOrchestration.dispose();

Permissions

The SEON SDK may require camera, microphone, and storage. Location is optional if your workflow uses it.

iOS (Info.plist)

<key>NSCameraUsageDescription</key>
<string>Required for ID verification and selfie capture</string>
<key>NSMicrophoneUsageDescription</key>
<string>Required for video liveness checks</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Required for proof of address document upload</string>

Android

The plugin merges required permissions into your app manifest. For location-based checks, add ACCESS_FINE_LOCATION and the matching iOS location usage key.
