Please note that this is the alpha version of the mParticle Flutter Plugin. Public APIs are subject to change before v1.0.0 is released.

Flutter allows developers to use a single code base to deploy to multiple platforms. Now, with the mParticle Flutter Plugin, you can leverage a single API to deploy your data to hundreds of integrations from your iOS, Android, and Web apps.

See the table below to see what features are currently supported. The Flutter mParticle plugin is under ongoing development and the goal is to fully support all the below features on all 3 core platforms.

  1. Add the Flutter SDK as a dependency to your Flutter application:
flutter pub add mparticle_flutter_sdk

Specifying this dependency adds a line like the following to your package's pubspec.yaml:

    mparticle_flutter_sdk: ^0.0.1
  1. Import the package into your Dart code:
import 'package:mparticle_flutter_sdk/mparticle_flutter_sdk.dart'

Now that you have the mParticle Dart plugin, install mParticle on your native/web platforms. Be sure to include an API Key and Secret where required or you will see errors in your logs when launching your app.


To install mParticle on an Android platform:

  1. Add the following dependencies to your app's build.gradle:
dependencies {
    implementation 'com.mparticle:android-core:5+'

    // Required for gathering Android Advertising ID (see below)
    implementation ''

    // Recommended to query the Google Play install referrer
    implementation ''
  1. Grab your mParticle key and secret from your workspace's dashboard and construct an MParticleOptions object.

  2. Call start from the onCreate method of your app's Application class. It's crucial that the SDK be started here for proper session management. If you don't already have an Application class, create it and then specify its fully-qualified name in the <application> tag of your app's AndroidManifest.xml.

package com.example.myapp;

import com.mparticle.MParticle;

public class MyApplication extends Application {
    public void onCreate() {
        MParticleOptions options = MParticleOptions.builder(this)
            .credentials("REPLACE ME WITH KEY","REPLACE ME WITH SECRET")
                new BaseIdentityTask()

import com.mparticle.MParticle
import com.mparticle.MParticleOptions

class ExampleApplication : Application() {
    override fun onCreate() {
        val options = MParticleOptions.builder(this)
            .credentials("REPLACE ME WITH KEY", "REPLACE ME WITH SECRET")

Warning: Don't log events in your Application.onCreate(). Android may instantiate your Application class for a lot of reasons, in the background, while the user isn't even using their device. For more help, see the Android set up docs.


Configuring iOS:

To install mParticle on an iOS platform:

  1. Copy your mParticle key and secret** from your app's dashboard.
  1. Install the SDK using CocoaPods:
$ # Update your Podfile to depend on 'mParticle-Apple-SDK' version 8.5.0 or later
$ pod install

The mParticle SDK is initialized by calling the startWithOptions method within the application:didFinishLaunchingWithOptions: delegate call. Preferably the location of the initialization method call should be one of the last statements in the application:didFinishLaunchingWithOptions:. The startWithOptions method requires an options argument containing your key and secret and an initial Identity request.

Note that you must initialize the SDK in the application:didFinishLaunchingWithOptions: method. Other parts of the SDK rely on the UIApplicationDidBecomeActiveNotification notification to function properly. Failing to start the SDK as indicated will impair it. Also, please do not use GCD's dispatch_async to start the SDK. For more help, see the full iOS set up docs.

  1. Import and start the mParticle Apple SDK into Swift or Objective-C.

Swift Example

import mParticle_Apple_SDK

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
       // Override point for customization after application launch.
        let mParticleOptions = MParticleOptions(key: "<<<App Key Here>>>", secret: "<<<App Secret Here>>>")
       //Please see the Identity page for more information on building this object
        let request = MPIdentityApiRequest() = ""
        mParticleOptions.identifyRequest = request
        mParticleOptions.onIdentifyComplete = { (apiResult, error) in
            NSLog("Identify complete. userId = %@ error = %@", apiResult?.user.userId.stringValue ?? "Null User ID", error?.localizedDescription ?? "No Error Available")
        mParticleOptions.onAttributionComplete = { (attributionResult, error) in
                    NSLog(@"Attribution Complete. attributionResults = %@", attributionResult.linkInfo)
       //Start the SDK
        MParticle.sharedInstance().start(with: mParticleOptions)
       return true

Objective-C Example

For apps supporting iOS 8 and above, Apple recommends using the import syntax for modules or semantic import. However, if you prefer the traditional CocoaPods and static libraries delivery mechanism, that is fully supported as well.

If you are using mParticle as a framework, your import statement will be as follows:

@import mParticle_Apple_SDK;                // Apple recommended syntax, but requires "Enable Modules (C and Objective-C)" in pbxproj
#import <mParticle_Apple_SDK/mParticle.h>   // Works when modules are not enabled

Otherwise, for CocoaPods without use_frameworks!, you can use either of these statements:

#import <mParticle-Apple-SDK/mParticle.h>
#import "mParticle.h"

Next, you'll need to start the SDK:

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

    MParticleOptions *mParticleOptions = [MParticleOptions optionsWithKey:@"REPLACE ME"
                                                                   secret:@"REPLACE ME"];
    //Please see the Identity page for more information on building this object
    MPIdentityApiRequest *request = [MPIdentityApiRequest requestWithEmptyUser]; = @"";
    mParticleOptions.identifyRequest = request;
    mParticleOptions.onIdentifyComplete = ^(MPIdentityApiResult * _Nullable apiResult, NSError * _Nullable error) {
        NSLog(@"Identify complete. userId = %@ error = %@", apiResult.user.userId, error);
    mParticleOptions.onAttributionComplete(MPAttributionResult * _Nullable attributionResult, NSError * _Nullable error) {
        NSLog(@"Attribution Complete. attributionResults = %@", attributionResult.linkInfo)
    [[MParticle sharedInstance] startWithOptions:mParticleOptions];
    return YES;

See Identity for more information on supplying an MPIdentityApiRequest object during SDK initialization.

Each of our Dart methods is mapped to an underlying mParticle SDK at the platform level. Note that per Dart's documentation(, calling into platform specific code is asynchronous to ensure the user interface remains responsive. In your code, you can swap usage between async and then in accordance to your app's requirements.


Importing the module:

import 'package:mparticle_flutter_sdk/mparticle_flutter_sdk.dart';

You must first call getInstance on MparticleFlutterSdk before each method is called. This ensures the underlying mParticle SDK has been initialized. Per Flutter's plugin documentation, messages between the Dart plugin and underlying platforms must be passed asynchronously to ensure the user interface remains responsive. Therefore, to ensure code is performant to your team's requirements, you may refactor instances of await with then and vice versa in the examples below.

MparticleFlutterSdk? mpInstance = await MparticleFlutterSdk.getInstance();

Log Events

To log events, import mParticle EventTypes and MPEvent to write proper event logging calls:

import 'package:mparticle_flutter_sdk/events/event_type.dart';
import 'package:mparticle_flutter_sdk/events/mp_event.dart';

MPEvent event = MPEvent('Clicked Search Bar', EventType.Search)
  ..customAttributes = { 'key1': 'value1' }
  ..customFlags = { 'flag1': 'value1' };

To log screen events, import mParticle ScreenEvent:

import 'package:mparticle_flutter_sdk/events/screen_event.dart';

ScreenEvent screenEvent = ScreenEvent('Screen event logged')
  ..customAttributes = { 'key1': 'value1' }
  ..customFlags = { 'flag1': 'value1' };

Commerce Events

To log product commerce events, import CommerceEvent, Product and ProductActionType (optionally TransactionAttributes)

import 'package:mparticle_flutter_sdk/events/commerce_event.dart';
import 'package:mparticle_flutter_sdk/events/product.dart';
import 'package:mparticle_flutter_sdk/events/product_action_type.dart';
import 'package:mparticle_flutter_sdk/events/transaction_attributes.dart';

final Product product1 = Product('Orange', '123abc', 5.0, 1);
final Product product2 = Product('Apple', '456abc', 10.5, 2);
final TransactionAttributes transactionAttributes =
  TransactionAttributes('123456', 'affiliation', '12412342',
      1.34, 43.232, 242.2323);
CommerceEvent commerceEvent = CommerceEvent.withProduct(ProductActionType.Purchase, product1)
    ..transactionAttributes = transactionAttributes
    ..currency = 'US'
    ..screenName = 'One Click Purchase';

To log promotion commerce events, import CommerceEvent, Promotion and PromotionActionType:

import 'package:mparticle_flutter_sdk/events/commerce_event.dart';
import 'package:mparticle_flutter_sdk/events/promotion.dart';
import 'package:mparticle_flutter_sdk/events/promotion_action_type.dart';

final Promotion promotion1 = Promotion('12312', 'Jennifer Slater', 'BOGO Bonanza', 'top');
final Promotion promotion2 = Promotion('15632', 'Gregor Roman', 'Eco Living', 'mid');

CommerceEvent commerceEvent = CommerceEvent.withPromotion(PromotionActionType.View, promotion1)
    ..currency = 'US'
    ..screenName = 'PromotionScreen';

To log impression commerce events, import CommerceEvent, Impression and Product

import 'package:mparticle_flutter_sdk/events/commerce_event.dart';
import 'package:mparticle_flutter_sdk/events/impression.dart';
import 'package:mparticle_flutter_sdk/events/product.dart';

final Product product1 = Product('Orange', '123abc', 2.4, 1);
final Product product2 = Product('Apple', '456abc', 4.1, 2);
final Impression impression1 = Impression('produce', [product1, product2]);
final Impression impression2 = Impression('citrus', [product1]);
CommerceEvent commerceEvent = CommerceEvent.withImpression(impression1)
  ..currency = 'US'
  ..screenName = 'ImpressionScreen';


Get the current user in order to apply and remove attributes, tags, etc.

var user = await mpInstance?.getCurrentUser();

User Attributes:

user?.setUserAttribute('age', '45');
user?.setUserAttributeArray('Test key', ['Test value 1', 'Test value 2']);
user?.getUserIdentities().then((identities) {
    print(identities); // Map<IdentityType, String>


IDSync is mParticle’s identity framework, enabling our customers to create a unified view of the customer. To read more about IDSync, see here.

All IDSync calls require an Identity Request.


import 'package:mparticle_flutter_sdk/identity/identity_type.dart';

var identityRequest = MparticleFlutterSdk.identityRequest;
    .setIdentity(IdentityType.CustomerId, 'customerid5')
    .setIdentity(IdentityType.Email, '');

After an IdentityRequest is passed to one of the following IDSync methods - identify, login, logout, or modify.

Import the SuccessResponse and FailureResponse classes to write proper callbacks for Identity methods. For brevity, we included an example of full error handling in only the identify example below, but this error handling can be used for any of the Identity calls.


The following is a full Identify example with error and success handling.

import 'package:mparticle_flutter_sdk/identity/identity_api_result.dart';
import 'package:mparticle_flutter_sdk/identity/identity_api_error_response.dart';

var request = MparticleFlutterSdk.identityRequest();

    .identify(identityRequest: identityRequest)
        (IdentityApiResult successResponse) =>
            print("Success Response: $successResponse"),
        onError: (error) {
            var failureResponse = error as IdentityAPIErrorResponse;
            print("Failure Response: $failureResponse");

            // It is possible for either a client error or a server error to occur during identity calls.
            // First check for the client side error, then you can check the http code for the server error.
            // More details can be found in the platform specific IDSync error handling:
                // iOS -
                // Web -
                // Android -
            if (failureResponse.clientErrorCode != null) {
                switch (failureResponse.clientErrorCode) {
                case IdentityClientErrorCodes.RequestInProgress:
                    // there is an Identity request in progress, wait for it to complete before attempting another
                case IdentityClientErrorCodes.ClientSideTimeout:
                case IdentityClientErrorCodes.ClientNoConnection:
                    // retry the IDSync request
                case IdentityClientErrorCodes.SSLError:
                    // SSL configuration issue. 
                case IdentityClientErrorCodes.OptOut:
                    // The user has opted out of data collection
                case IdentityClientErrorCodes.Unknown:
                case IdentityClientErrorCodes.ActiveSession:
                case IdentityClientErrorCodes.ValidationIssue:
                    // A web error that should never arise due to Dart's stronger typing
                case IdentityClientErrorCodes.NativeIdentityRequest:
            int? httpCode = failureResponse.httpCode;
            if (httpCode != null && httpCode >= 400) {
                switch (httpCode) {
                case 400:
                case 401:
                case 429:
                case 529:
                        (error) => print('${error.code}\n${error.message}'));


var identityRequest = MparticleFlutterSdk.identityRequest;
    .setIdentity(IdentityType.CustomerId, 'customerid2')
    .setIdentity(IdentityType.Email, '');

    .login(identityRequest: identityRequest)
        (IdentityApiResult successResponse) =>
            print("Success Response: $successResponse"),
        onError: (error) {
            var failureResponse = error as IdentityAPIErrorResponse;
            print("Failure Response: $failureResponse");


var identityRequest = MparticleFlutterSdk.identityRequest;
    .setIdentity(IdentityType.CustomerId, 'customerid3')
    .setIdentity(IdentityType.Email, '');

    .modify(identityRequest: identityRequest)
        (IdentityApiResult successResponse) =>
            print("Success Response: $successResponse"),
        onError: (error) {
            var failureResponse = error as IdentityAPIErrorResponse;
            print("Failure Response: $failureResponse");


var identityRequest = MparticleFlutterSdk.identityRequest;
// depending on your identity strategy, you may have identities added to your identityRequestk

    .logout(identityRequest: identityRequest)
        (IdentityApiResult successResponse) =>
            print("Success Response: $successResponse"),
        onError: (error) {
            var failureResponse = error as IdentityAPIErrorResponse;
            print("Failure Response: $failureResponse");

Aliasing Users

This is a feature to transition data from "anonymous" users to "known" users. To learn more about user aliasing, see here.

mpInstance?.identity.login(identityRequest: identityRequest).then(
    (IdentityApiResult successResponse) {
        String? previousMPID = successResponse.previousUser?.getMPID();
        if (previousMPID != null) {
            var userAliasRequest = AliasRequest(
                previousMPID, successResponse.user.getMPID()
            mpInstance?.identity.aliasUsers(aliasRequest: userAliasRequest);

Native-only Methods

A few methods are currently supported only on iOS/Android SDKs:

  • Get the SDK's opt out status -

      var isOptedOut = await mpInstance?.getOptOut;
      mpInstance?.setOptOut(optOutBoolean: !isOptedOut!);
  • Check if a kit is active

      import 'package:mparticle_flutter_sdk/kits/kits.dart';
      mpInstance?.isKitActive(kit: Kits['Braze']!).then((isActive) {
  • Push Registration

    The method mpInstance.logPushRegistration() accepts two parameters. For Android, provide both pushToken and senderId. For iOS, provide the push token in the first parameter, and simply pass null for the second parameter


      mpInstance?.logPushRegistration(pushToken: 'pushToken123', senderId: 'senderId123');


      mpInstance?.logPushRegistration(pushToken: 'pushToken123', senderId: null);
  • Set App Tracking Transparency (ATT) Status

    For iOS, you can set a user's ATT status as follows: import 'package:mparticle_flutter_sdk/apple/authorization_status.dart';

            attStatus: MPATTAuthorizationStatus.Authorized,
