ViaLink 딥링크 SDK for Flutter - 네이티브 SDK 기반 브릿지 플러그인

ViaLink Flutter SDK

English | 한국어

ViaLink deep link SDK for Flutter — a bridge plugin built on the native SDKs (AAR/XCFramework).

Features

• Deep link routing — automatic handling of App Links / Universal Links
• Deferred deep linking — fingerprint-based matching on the first launch after install
• Event tracking — batched delivery of custom events
• Payment attribution — records payment attempts and automatically attaches link_id
• Link creation — generate deep links from within the app (static/dynamic)

Installation

dependencies:
  vialink_flutter_plugin: ^3.2.15

Usage

1. Initialization

import 'package:vialink_flutter_plugin/vialink_flutter_plugin.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await ViaLinkSDK.instance.configure(apiKey: 'YOUR_API_KEY');
  runApp(MyApp());
}

2. Deep link callbacks

// Receive App Links / Universal Links
ViaLinkSDK.instance.onDeepLink((data) {
  Navigator.pushNamed(context, data.path);
  print('params: ${data.params}');
});

// Deferred deep link (matched after the first install)
ViaLinkSDK.instance.onDeferredDeepLink((data, error) {
  if (error != null) {
    print('deferred match failed: ${error.message}');
    return;
  }
  if (data != null) {
    print('deferred match succeeded: ${data.path}');
    Navigator.pushNamed(context, data.path);
  } else {
    print('no match (organic install)');
  }
});

3. Pull API

// Synchronous (returns the cached value immediately)
final deepLink = ViaLinkSDK.instance.getDeepLinkData();
final deferred = ViaLinkSDK.instance.getDeferredLinkData();

// Asynchronous (waits until the result arrives)
final deepLinkAsync = await ViaLinkSDK.instance.awaitDeepLinkData();    // 3-second timeout
final deferredAsync = await ViaLinkSDK.instance.awaitDeferredLinkData(); // waits until the result

4. Event tracking

ViaLinkSDK.instance.track('purchase', data: {
  'product_id': '123',
  'revenue': '29900',
  'currency': 'KRW',
});

5. Payment tracking

final result = await ViaLinkSDK.instance.trackPayment(
  orderId: 'ORD-2026-0001',
  amount: 19900,
  currency: 'KRW',
  paymentMethod: 'card',
);
print('success: ${result.success}, id: ${result.paymentEventId}');

6. Link creation

final url = await ViaLinkSDK.instance.createLink(
  path: '/product/123',
  data: {'promo_code': 'FRIEND'},
  campaign: 'referral',
  linkType: 'dynamic', // when click tracking is needed
);
print('created link: $url');
