gomarketme 5.0.3

Affiliate Marketing for Flutter-Based iOS and Android Apps.

GoMarketMe Flutter SDK

Affiliate marketing for Flutter apps on iOS and Android.

Installation

Run this command:

flutter pub add gomarketme

This will add a line like this to your app's pubspec.yaml and run an implicit flutter pub get:

dependencies:
  gomarketme: ^5.0.3

Usage

GoMarketMe takes only a few lines to set up.

Step 1/3: Initialize

Import gomarketme and initialize the SDK with your GoMarketMe API key.

import 'package:flutter/widgets.dart';
import 'package:gomarketme/gomarketme.dart';

final goMarketMeSDK = GoMarketMe();

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  goMarketMeSDK.initialize('API_KEY');

  runApp(const MyApp());
}

Replace API_KEY with your actual GoMarketMe API key. You can find it on the product onboarding page and under Profile > API Key.

Alternative Step 1/3: Programmatic Affiliate Marketing

For apps that want to customize the user experience based on affiliate attribution, initialize GoMarketMe and read affiliate marketing data after initialization.

This enables Programmatic Affiliate Marketing, including affiliate-aware paywalls, personalized onboarding, promotions, and custom in-app experiences.

import 'package:flutter/material.dart';
import 'package:gomarketme/gomarketme.dart';

final goMarketMeSDK = GoMarketMe();
GoMarketMeAffiliateMarketingData? affiliateData;

Future<void> initializeGoMarketMe(String apiKey) async {
  await goMarketMeSDK.initialize(apiKey);

  final data = goMarketMeSDK.affiliateMarketingData;

  if (data == null) {
    debugPrint('No GoMarketMe affiliate data found.');
    return;
  }

  // Maps to GoMarketMe > Affiliates > Export > id column.
  debugPrint('Affiliate ID: ${data.affiliate.id}');

  // Maps to GoMarketMe > Campaigns > [Name] > Affiliate\'s Revenue Split (%).
  debugPrint('Affiliate %: ${data.saleDistribution.affiliatePercentage}');

  // Maps to GoMarketMe > Campaigns > [Name] > id in the URL.
  debugPrint('Campaign ID: ${data.campaign.id}');

  // Use this data to customize onboarding, paywalls, promotions, or in-app experiences.
  affiliateData = data;
}

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await initializeGoMarketMe('API_KEY');

  runApp(const MyApp());
}

Step 2/3: Sync after purchase

After your app completes a purchase through in_app_purchase, RevenueCat, Adapty, or another in-app purchase provider, call:

await goMarketMeSDK.syncAllTransactions();

If your purchase library lets you decide when to finish, acknowledge, consume, or complete the transaction, call syncAllTransactions() first.

final purchaseParam = PurchaseParam(productDetails: productDetails);
await InAppPurchase.instance.buyConsumable(purchaseParam: purchaseParam);

// After you receive a successful purchase update:
await goMarketMeSDK.syncAllTransactions();
await InAppPurchase.instance.completePurchase(purchaseDetails);

Step 3/3: iOS consumables only

If your iOS app sells consumable in-app purchases, add this key to your app's ios/Runner/Info.plist:

<key>SKIncludeConsumableInAppPurchaseHistory</key>
<true/>

That's it. GoMarketMe automatically attributes and reports affiliate sales.
