Track events and revenue with Apple Search Ads attribution in your Flutter app.

pub.dev repository

Here, you will find the pub.dev appstack_plugin documentation. Please use the latest available version of the SDK.

Requirements

iOS

• iOS version: 13.0+ (14.3+ recommended for Apple Ads)
• Xcode: 14.0+

Android

• Minimum SDK: Android 5.0 (API level 21)
• Target SDK: 34+

General

• Flutter: 3.3.0+
• Dart: 2.18.0+

Initial setup

Advanced usage

Environment-based configuration

Set up different API keys for different environments:

// Use environment variables or configuration
final apiKey = Platform.isIOS 
    ? const String.fromEnvironment('APPSTACK_IOS_API_KEY')
    : const String.fromEnvironment('APPSTACK_ANDROID_API_KEY');

await AppstackPlugin.configure(apiKey);

Platform-specific considerations

iOS

Apple Ads attribution:

• Only works on iOS 14.3+
• Requires app installation from App Store or TestFlight
• Attribution data appears within 24-48 hours
• User consent may be required for detailed attribution (iOS 14.5+)

if (Platform.isIOS) {
  await AppstackPlugin.enableAppleAdsAttribution();
}

Android

Play Store Attribution

• Install referrer data collected automatically
• Attribution available immediately for Play Store installs
• Works with Android 5.0+ (API level 21)

Cross-platform best practices

Future<void> initializeSDK() async {
  final apiKey = Platform.isIOS 
      ? 'your-ios-api-key' 
      : 'your-android-api-key';

  final configured = await AppstackPlugin.configure(apiKey);
  
  if (configured && Platform.isIOS) {
    await AppstackPlugin.enableAppleAdsAttribution();
  }

Limitations

Attribution timing

• iOS: Apple Ads attribution data appears within 24-48 hours after install
• Android: Install referrer data available immediately for Play Store installs
• Attribution only available for apps installed from official stores

Platform constraints

• iOS: Requires iOS 14.3+
• Android: Minimum API level 21 (Android 5.0)
• Flutter: 3.3.0+
• Some Apple Ads features may not work in development/simulator environments

Event tracking

• Event names are case-sensitive and standardized
• For revenue events, always pass a revenue (or price) and a currency parameter
• The SDK must be initialized before any tracking calls
• enableAppleAdsAttribution() only works on iOS and returns false on Android
• Network connectivity required for event transmission (events are queued offline)
