Quick start

Track your first install in under 5 minutes.

import 'package:appfiliate/appfiliate.dart';

// In main() or initState():
Appfiliate.configure(appId: 'APP_ID', apiKey: 'API_KEY');
await Appfiliate.trackInstall();

Get your App ID and API Key from your Appfiliate dashboard.

Integration guide

Step-by-step instructions to integrate the Appfiliate Flutter SDK.

1

Add the dependency

Add to your pubspec.yaml:

dependencies:
  appfiliate: ^1.0.0

Then run:

flutter pub get
2

Configure and track installs

Find your main() function or your main widget's initState. Add the following:

import 'package:appfiliate/appfiliate.dart';

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

  Appfiliate.configure(appId: 'APP_ID', apiKey: 'API_KEY');
  await Appfiliate.trackInstall();

  runApp(const MyApp());
}

trackInstall() only fires once per install — it's safe to call on every launch.

3

Track purchases (optional)

After a successful in-app purchase, call trackPurchase():

await Appfiliate.trackPurchase(
    productId: 'premium_monthly',
    revenue: 9.99,
    currency: 'USD',
    transactionId: purchaseDetails.purchaseID,
);
4

Set user ID for webhooks (optional)

If you use RevenueCat, Superwall, Adapty, Qonversion, or Stripe, link the user ID so purchases are attributed automatically:

// RevenueCat example
await Appfiliate.setUserId(await Purchases.appUserID);

// Stripe example
await Appfiliate.setUserId(stripeCustomerId);

Automatic Purchase Tracking

RevenueCat webhook integration

Connect RevenueCat and every purchase, renewal, and cancellation is attributed automatically. No manual trackPurchase() calls needed.

1. Add one line of code

Appfiliate.configure(appId: 'APP_ID', apiKey: 'API_KEY');
await Appfiliate.trackInstall();
await Appfiliate.setUserId(await Purchases.appUserID);

2. Paste the webhook URL

In your RevenueCat dashboard, go to Integrations → Webhooks and paste:

https://us-central1-appfiliate-5a18b.cloudfunctions.net/api/v1/webhooks/revenuecat

Also works with Superwall, Adapty, Qonversion, and Stripe.
