Basic Integration

You can add Singular Plugin to your Flutter app by adding following to your pubspec.yaml file:

dependencies:
  singular_flutter_sdk: ^1.0.9

Then navigate to your project in the terminal and run:

flutter packages get

Before you initialize the Singular SDK, you have to create a SingularConfig object. The object contains your API key and API secret for the Singular SDK. Optionally, you can add settings to enable various SDK features.

Example:

import 'package:singular_flutter_sdk/singular.dart';
import 'package:singular_flutter_sdk/singular_config.dart';

SingularConfig config = new SingularConfig('API_KEY', 'API_SECRET');
config.customUserId = "[email protected]";
Singular.start(config);

Tracking Events

You can send events to Singular using the event and eventWithArgs methods.

Example:

Singular.event(eventName);

Singular.eventWithArgs(eventName, {"level-up":"5"});

Tracking Revenues

Report a custom event to Singular

Example:

Singular.customRevenue("MyCustomRevenue", "USD", 5.50);

Report an IAP event to Singular

Example:

import 'package:singular_flutter_sdk/singular_iap.dart';

 singularPurchase = new SingularIOSIAP(
   product.price,
   product.currencyCode,
   purchase.productId,
   purchase.purchaseId,
   purchase.verificationData.serverVerificationData
 );

 singularPurchase = new SingularAndroidIAP(
   product.price,
   product.currencyCode,
   purchase.singature,
   purchase.verificationData.serverVerificationData
 );

Singular.inAppPurchase(eventName, singularPurchase);

Implementing Deeplinks

To enable Singular Links in iOS and in Android, see Singular Links Prerequisites.

Handling Singular Links

The Singular SDK provides a handler mechanism to read the details of the tracking link that led to the app being opened.

Example:

SingularConfig config = new SingularConfig('API_KEY', 'API_SECRET');
    config.singularLinksHandler = (SingularLinkParams params) {
    String deeplink = params.deeplink;
    String passthrough = params.passthrough;
    bool isDeferred = params.isDeferred;
    // Add your code here to handle the deep link
});
Singular.init(config);

iOS Prerequisites

Objective-C:

In the project’s AppDelegate.m, add the following:

// Top of the AppDelegate.m
#import "SingularAppDelegate.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  [GeneratedPluginRegistrant registerWithRegistry:self];

  [SingularAppDelegate shared].launchOptions = launchOptions;
  return [super application:application didFinishLaunchingWithOptions:launchOptions];

  }

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray<id<UIUserActivityRestoring>> *restorableObjects))restorationHandler {

  [[SingularAppDelegate shared] continueUserActivity:userActivity restorationHandler:restorationHandler];
  return YES;

  }

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {

    [[SingularAppDelegate shared] handleOpenUrl:url options:options];
    return YES;

  }

Swift:

import singular_flutter_sdk

override func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    if let singularAppDelegate = SingularAppDelegate.shared() {
        singularAppDelegate.launchOptions = launchOptions
    }
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
    
override func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
    if let singularAppDelegate = SingularAppDelegate.shared() {
        singularAppDelegate.continueUserActivity(userActivity, restorationHandler: nil)
    }
   return true
}
    
override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    if let singularAppDelegate = SingularAppDelegate.shared() {
        singularAppDelegate.handleOpen(url, options: options)
    }
   return true
}
    

Android Prerequisites

Java:

In the project’s MainActivity.java, add the following:

import com.singular.flutter_sdk.SingularBridge;

@Override
protected void onNewIntent(@NonNull Intent intent) {
  super.onNewIntent(intent);
  SingularBridge.onNewIntent(intent);
}

Kotlin:

import com.singular.flutter_sdk.SingularBridge;

override fun onNewIntent(intent: Intent) {
  super.onNewIntent(intent)
  SingularBridge.onNewIntent(intent);
}

Adding SKAdNetwork Support

To enable SKAdNetwork tracking for your app, turn on the skAdNetworkEnabled configuration option before initializing Singular:

Example:

SingularConfig config = new SingularConfig('API_KEY', 'API_SECRET');
config.skAdNetworkEnabled = true;
config.manualSkanConversionManagement = true; // Enable manual conversion value updates
config.conversionValueUpdatedCallback = (int conversionValue) {
     print('Received conversionValueUpdatedCallback: ' + conversionValue.toString());
};
Singular.init(config);

Retrieving the Conversion Value

Singular.skanGetConversionValue().then((conversionValue) {
     print('conversion value: ' + conversionValue.toString());
});

Tracking Uninstalls

Send Singular the APNS/FCM token in order to let it track app uninstalls.

Example:

//iOS
  Singular.registerDeviceTokenForUninstall(apnsToken);

//Android
  Singular.registerDeviceTokenForUninstall(fcmToken);
