API Methods

Getting started

In order to install the plugin, visit this page.

To start using AppsFlyer you first need to create an instance of AppsflyerSdk before using any other of our sdk functionalities.

AppsflyerSdk(Map options)
optionsMapSDK configuration


afDevKeystringAppsflyer Dev key
afAppIdstringApple Application ID (for iOS only)
isDebugbooleanfalsedebug mode (optional)


import 'package:appsflyer_sdk/appsflyer_sdk.dart';

Map options = { "afDevKey": afDevKey,
                "afAppId": appId,
                "isDebug": true};

AppsflyerSdk appsflyerSdk = AppsflyerSdk(appsFlyerOptions);

Or you can use AppsFlyerOptions class instead

AppsflyerSdk(Map options)
optionsAppsFlyerOptionsSDK configuration


import 'package:appsflyer_sdk/appsflyer_sdk.dart';

final AppsFlyerOptions options = AppsFlyerOptions(afDevKey: "af dev key",
                                                  showDebug: true,
                                                  appId: "123456789");

Once AppsflyerSdk object is created, you can call initSdk method.

static Future<Map<dynamic, dynamic>> initSdk({bool registerConversionDataCallback, bool registerOnAppOpenAttributionCallback}) async (Changed in 1.2.2)

initialize the SDK, using the options initialized from the constructor| Return response object with the field status The user can access conversionDataStream and appOpenAttributionStream to listen for events


import 'package:appsflyer_sdk/appsflyer_sdk.dart';

AppsflyerSdk _appsflyerSdk = AppsflyerSdk({...});

FutureBuilder<dynamic> ( future: _appsflyerSdk.initSdk(registerConversionDataCallback: true, registerOnAppOpenAttributionCallback: true), builder: (BuildContext context, AsyncSnapshot snapshot) {
  if (snapshot.hasData)
    return  HomeContainer(
      onData: _appsflyerSdk.conversionDataStream,
      onAttribution: _appsflyerSdk.appOpenAttributionStream,

static Future<bool> trackEvent(String eventName, Map eventValues) async (optional)
  • These in-app events help you track how loyal users discover your app, and attribute them to specific campaigns/media-sources. Please take the time define the event/s you want to measure to allow you to track ROI (Return on Investment) and LTV (Lifetime Value).
  • The trackEvent method allows you to send in-app events to AppsFlyer analytics. This method allows you to add events dynamically by adding them directly to the application code.
eventNameStringcustom event name, is presented in your dashboard. See the Event list HERE
eventValuesMapevent details


Future<bool> sendEvent(String eventName, Map eventValues) async {
    bool result;
    try {
      result = await appsflyerSdk.trackEvent(eventName, eventValues);
    } on Exception catch (e) {}
      print("Result trackEvent: ${result}");

Conversion Data and on app open attribution

static Stream<dynamic> registerConversionDataCallback()

Returns Stream. Accessing AppsFlyer Attribution / Conversion Data from the SDK (Deferred Deeplinking). Read more: Android, iOS. AppsFlyer plugin will return attribution data as JSON Map in Stream.


appsflyerSdk.registerConversionDataCallback().listen((data) {
      //print("GCD: " + data.toString());
    }).onError((handleError) {

Example of success Organic response:

  "status": "success",
  "type": "onInstallConversionDataLoaded",
  "data": {
    "af_status": "Organic",
    "af_message": "organic install",
    "is_first_launch": "false"

Example of failure response:

  "status": "failure",
  "type": "onInstallConversionDataLoaded",
static Stream<dynamic> registerOnAppOpenAttributionCallback()

In case you want to use deep links in your app, you will need to use registerOnAppOpenAttributionCallback on the AppsflyerSdk instance you've created.

appsflyerSdk.registerOnAppOpenAttributionCallback().listen((data) {
      //print("OnAppOpenAttribution: " + data.toString());
    }).onError((handleError) {

Example of response on deep-link "https://flutter.demo" :

  "status": "success",
  "type": "onAppOpenAttribution",
  "data": {
    "link": "https://flutter.demo"

Android Out of store

Please make sure to go over this guide to get general understanding of how out of store attribution is set up in AppsFlyer. If the store you distribute the app through supports install referrer matching or requires the referrer in the postback, make sure to add the following to the AndroidManifest.xml:

	<receiver android:name="com.appsflyer.SingleInstallBroadcastReceiver" android:exported="true">
			 <action android:name="" />

Other functionalities:

void setUserEmails(List<String> emails, [EmailCryptType cryptType] Set the user emails with the given encryption (EmailCryptTypeNone, EmailCryptTypeSHA1, EmailCryptTypeMD5, EmailCryptTypeSHA256). the default encryption is EmailCryptTypeNone. Example:

       ["", ""], EmailCryptType.EmailCryptTypeSHA1);

void setMinTimeBetweenSessions(int seconds) You can set the minimum time between session (the default is 5 seconds)


void stopTracking(bool isTrackingStopped) You can stop sending events to Appsflyer by using this method. Example:


void setCurrencyCode(String currencyCode) Example:


void setIsUpdate(bool isUpdate) Example:


void enableUninstallTracking(String senderId) Example:


void setImeiData(String imei) Example:


void setAndroidIdData(String androidIdData) Example:


void enableLocationCollection(bool flag) Example:


void setCustomerUserId(String userId) What is customer user id? Example:


void waitForCustomerUserId(bool wait) You can set this function to true if you don't want to track events without setting customer id first. Example:


void setAdditionalData(Map addionalData) Example:

appsFlyerSdk.setAdditionalData({"customData": "data"});

void setCollectAndroidId(bool isCollect) Example:


void setCollectIMEI(bool isCollect)
NOTE: Make sure to add <uses-permission android:name="android.permission.READ_PHONE_STATE" /> in the AndroidManifest and request these permissions in the runtime in order for the SDK to be able to collect IMEI Example:


void setHost(String hostPrefix, String hostName) You can change the default host (appsflyer) by using this function Example:

appsFlyerSdk.setHost("pref", "my-host");

Future<String> getHostName() Example:

appsFlyerSdk.getHostName().then((name) {
         print("Host name: ${name}");

Future<String> getHostPrefix() Example:

appsFlyerSdk.getHostPrefix().then((name) {
         print("Host prefix: ${name}");

void updateServerUninstallToken(String token) Example:


Stream validateAndTrackInAppPurchase( String publicKey, String signature, String purchaseData, String price, String currency, Map<String, String> additionalParameters) Example:

           {"fs": "fs"}).listen((data) {
       }).onError((error) {
