This is the official Amplitude Flutter SDK developed and maintained by Amplitude Inc.

Installation and Quick Start

• Please visit our 💯Developer Center for instructions on installing and using our the SDK.
• For developing the SDK, please visit our CONTRIBUTING.md to get started.

Compatibility

From Amplitude Flutter v3.11.0, we bump up the kotlin version to v1.7.10 to support latest Gradle. For Gradle Version lower than v6.7.1, we recommend to use the Amplitude Flutter v3.10.0. The following matrix lists the minimum support for Amplitude Flutter SDK version.

Amplitude Flutter	Gradle	Android Gradle Plugin	Kotlin Gradle Plugin
3.11.+	6.7.1	3.6.4	1.7.10

amplitude-flutter's Issues

com.amplitude.api.AmplitudeClient: context cannot be null, set context with initialize() before calling logEvent()

Expected Behavior

logEvent() should be worked correctly

Current Behavior

Got exception after logEvent() function

Possible Solution

According to the log, set context correctly in amplitude sdk can fix this issue.

Steps to Reproduce

Build apk with flutter 1.22.4 and invoke logEvent by amplitude.dart.

Environment

• SDK Version: 2.2.3
• Flutter Version: 1.22.4
• Device: Pixel 3
• Device OS and Version: Android 11

Past data updated todays without any forced customizing

My team just figure out that past data can updated in spite of days ago.
When we service web page with amplitude javascript previously, this case does not happened.
So, my company asking for why this situation happening.
And we've got answered like this; ' This is flutter issue. In flutter library, event fullfil with 30 events then it goes to server. '

I think this can be a little bit critical issue.
I guess, according to that answer, we cannot see whole data with amplitude because if someone's events are less than 30, then we can't get any events with that customer.

So, I wish that amplitude flutter library enhanced as soon as possible.

Always thanks to your service :D

iOS crashes with no trace when .setUserId(null) is called.

Hi! Awesome library btw. Helps my startup stay legal, lol.

Please note, that this code crashes only on iOS, not Android.

This is the relevant code:

  AmplitudeService({
    @required this.apiKey,
    @required this.userLocale,
    @required this.resolvedLocale,
    @required this.optOut,
  }) {
    _client = Amplitude.getInstance(instanceName: 'turnip');
    _client.init(apiKey);
    _client.enableCoppaControl();
    _client.trackingSessionEvents(true);
    _client.setOptOut(optOut);
  }

  void setToken(Token token) {
    if (token == null) {
       _client.setUserId(
        null,
        startNewSession: true,
      );
    } else {
      // set user id
      final userId = token?.userId;
      _client.setUserId(userId);

      final userRole = token?.userRole;
      final subsCategory = token?.subscriptionCategory;

      _client.setUserProperties({
        'userRole': userRole,
        'subscriptionCategory': subsCategory,
      });
    }
  }

Here in void setToken, if token == null, _client.setUserId crashes the whole app and leaves no trace. The same thing happens even if I do not specify startNewSession: true.

If I comment out the _client.setUserId(null). Everything works as expected.

To be honest this is not the end of the world and does not dilute the data too much. But it would be handy to be able to "sign out" a user and be able to there and then start a new session.

Am I doing it wrong perhaps?

Google Play Services SDK not found for app set id!

Summary

Is it considered an error for Amplitude? Can it function with this error, I haven't published my app yet.

Only few of the events get synced to the amplitude dashboard

we have the app which has lots of event. only the events on the home page are getting reported accurately. if the user starts navigating to other screens the event start getting missed even though it is being called accurately. there is no exception related to any thing in the code. plus we have tried to run it in debug mode set to catch all exceptions and there is none.

Expected Behavior

All of the event should be reported perfectly fine.

Current Behavior

some events don't get reported. they don't follow any specific pattern. sometime it keeps on reporting way past few screen sometimes it stops no concentrate way to reproduce that..

Possible Solution

is there a way to turn the dubgging on for the sdk?? to check what's exactly going on there??

Steps to Reproduce

just start the app
navigate back and forth few screens then event will eventually be stopped and you will not see any thing on dashboard.
sometime it keeps on going and only certain events doesn't get sent.
the specific even we are consistently having issue with is "join call" event.

Environment

• SDK Version: ^3.8.1
• Flutter Version: 2.10.2
• Device: Poco X3, oneplus, emulator almost all of the devices
• Device OS and Version: android 11, android 12.

Android sessions not being reported the same as iOS sessions.

Expected Behavior

When I set up the SDK according to the documentation then the start of a user's session should be reported the same for iOS and Android.

Current Behavior

iOS will report when a session starts/ends but android does not.

Possible Solution

The only solution I have found is to call analytics.logEvent() to get data showing up for android.

Steps to Reproduce

1. Create a project from the amplitude flutter example app
2. In the my_app.dart file change the initState() to match the getting started guide.

  @override
  void initState() {
    super.initState();

    analytics = Amplitude.getInstance();
    analytics.init(widget.apiKey);
    analytics.setUserId("test_user");
    analytics.trackingSessionEvents(true);
  }

3. Running this for iOS will send data to the web interface
4. Running this for android will NOT send data to the web interface

Environment

• SDK Version: v3.2.1
• Flutter v2.2.2
• Device: iPhone 11Pro Simulator, Pixel 2
• Device OS and Version: iOS 14.5, Android 11

Linux Support

I develop my app for Android, iOS, Windows, macOS and Linux.
It would be great if you provide support for Linux.

Flutter Web Support

How can we get started to use this on Flutter Web?

Steps to Reproduce

1. Create any fresh flutter project.
2. Add platform :ios, '10.0' to your Podfile.
3. Add amplitude_flutter: 3.8.0 to pubspec.yaml file.
4. Run on iOS simulator.

Expose setOffline

Summary

Expose setOffline via the flutter plugin

Both objective-c and Kotlin counterparts offer a method 'setOffline'.

/**
     * Sets offline. If offline is true, then the SDK will not upload events to Amplitude servers;
     * however, it will still log events.
     *
     * @param offline whether or not the SDK should be offline
     * @return the AmplitudeClient
     */
    public AmplitudeClient setOffline(boolean offline) {
        this.offline = offline;

        // Try to update to the server once offline mode is disabled.
        if (!offline) {
            uploadEvents();
        }

        return this;
    } 

- (void)setOffline:(BOOL)offline {
    _offline = offline;

    if (!_offline) {
        [self uploadEvents];
    }
}

Motivations

Prevent uploading events to Amplitude server in special conditions.

java.lang.NoSuchMethodError: No static method userAgent ()

Current Behavior

The error occurs:
java.lang. NoSuchMethodError: Nostaticmethod user Agent()Ljava/Lang/String; in classLokhttp3
Occurs at the initialization stage of the plugin, when the init() method is called, after that the application crashes.

Possible Solution

It is the result of incompatibility of the versions of okhttp3 in different plugins/ libraries of the project, since many other libraries use the version of the okhttp API 3.12.+.
To solve the problem, you need to build from the build file.gradle should remove an explicit reference to the version of okhttp3 4.2.2, since these different versions of the okhttp3 API are not compatible in the same project.

error from OkHttp with Amplitude init() from android app

Steps to Reproduce

1. use flutter command to create a new project
2. try to init amplitude

not sure is here the right place to ask, but seems amplitude functionality is working properly, just wonder is there a way to avoid this error message?

Adjust + Amplitude broken on Android

Expected Behavior

[adjust] Install is displayed on Android & iOS

Current Behavior

[adjust] Install is only displayed on iOS

Possible Solution

The root of the problem is Android Amplitude SDK, logs show:

W/com.amplitude.api.DeviceInfo( 3416): Google Play Services not available for advertising id
W/com.amplitude.api.DeviceInfo( 3416): Google Play Services SDK not found for app set id!

Seems like class com.google.android.gms.ads.identifier.AdvertisingIdClient is not getting found in DeviceInfo.java

Followed all the instructions regarding the gradle/proguard setup.

Someone suggested a fix (not using reflection), but afaik it got dismissed dantetam/Amplitude-Android@39c70ab due to "we would have to change our tests" 🤷‍♀️

Now Adjust SDK seems to find and assign advertising id on Android just fine. My fix introduces option to set custom advertising id, this involves changes in both Android and Flutter repos:

• Android PR
• Flutter PR

Then I can simply use it at initialisation time and supply valid advertising id:

final amplitude = Amplitude.getInstance();
final adId = await Adjust.getGoogleAdId();
await amplitude.setCustomAdvertisingId(advertisingId);

This fixed problem we saw in our amplitude dashboard.

Steps to Reproduce

1. Integrate Flutter Amplitude SDK
2. Integrate Flutter Adjust SDK
3. Publish your apps
4. Observe Adjust install events are reported on iOS while not reported on Android

Environment

• SDK Version: 3.8.1
• Flutter Version: 2.10 stable
• Device: any Android
• Device OS and Version: any Android

Why minimal ios deployment target is 10?

Summary

I understand that the usage was very low. But my company needs to support ios 9+.
Is there any reason to no support iOS 9?

Implements Amplitude with flutter_segment package

We are trying to implement this package for segment and amplitude integration all at the flutter level.
https://pub.dev/packages/flutter_segment
https://pub.dev/packages/flutter_segment#setting-the-options-globally

The flutter_segment package to identify the user asks me for a session_id but when trying to get this session_id with the amplitude package it always returns -1.

My question is, what would be the best practice to integrate these two packages, maybe there is any suggestion?

As far as I understand I need to identify the user to get a session Id, maybe it works in a similar way with the anonimus id that segment provides?

Windows Support

I develop my app for Android, iOS, Windows, macOS and Linux.
It would be great if you provide support for Windows.

PlatformException(error, TypeError: Cannot read properties of undefined (reading 'getInstance'), null, null)

Expected Behavior

Amplitude should get initialized on Web

Current Behavior

I get an error instead when I run the code on the web but it works on mobile
PlatformException(error, TypeError: Cannot read properties of undefined (reading 'getInstance'), null, null)

Possible Solution

Steps to Reproduce

1. Add amplitude ^3.8.0 to flutter project
2. Try initializing amplitude with the following code

Amplitude amplitude = Amplitude.getInstance();
amplitude.init(Config.amplitudeAppId);

Environment

• SDK Version: ^3.8.0
• Flutter Version: 2.5.1
• Device: Chrome
• Device OS and Version: Web, Chrome Version 96.0.4664.55 on Mac

Pod install fail

Hello, amplitude_flutter 2.0 doesn't work on ios :

 pod install    
Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "Amplitude":
  In Podfile:
    amplitude_flutter (from `.symlinks/plugins/amplitude_flutter/ios`) was resolved to 0.0.1, which depends on
      Amplitude (= 5.1.0)

Specs satisfying the `Amplitude (= 5.1.0)` dependency were found, but they required a higher minimum deployment target.

"pod deintegrate"
"pod install"
"pod update"

doesn't work ! Any idea ?

Thx for your time

Unable to see event on Amplitude

Hi, I'm using Amplitude on 2.0.0 version and I'm trying to log an event to my dashboard, but unsuccessful, I'd like your help.

import 'package:adam/app_config.dart';
import 'package:amplitude_flutter/amplitude.dart';

class AppAnalytics extends Amplitude {
  static final AppAnalytics _analytics = AppAnalytics._internal();

  AppAnalytics._internal() : super('MyCompany');

  factory AppAnalytics() => _analytics;

  static Future<void> start() async {
    await _analytics.init(AppConfig.instance.analyticsKey);
  }

  static void initTrackWithUserId(String userId, {String screenName}) {
    _analytics
      ..setUserId(userId)
      ..trackingSessionEvents(true)
      ..logEvent('acessed_$screenName');
  }

  static void sendEvent(String event, {Map<String, dynamic> props}) {
    _analytics.logEvent(event, eventProperties: props);
  }
}

I've built this Singleton class and I'm starting at main.dart calling start() above.

I have some previous events that are logging but I'm trying to add new ones but they don't show up at Amplitude for me and I don't know what else to do, besides that, I have some questions.

What is the instanceName? It's the my project's name on Amplitude? My workspace name? Or can it be any name as I wish?

Using as a singleton is doing fine with some old events, but new ones, don't.

Am I missing something? Does the singleton is a good way to keep going?

Cocoa pods error preventing build

Hello,
Since the current stable release of Flutter the following error is happening:

Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "Amplitude":
  In snapshot (Podfile.lock):
    Amplitude (= 5.1.0)

  In Podfile:
    amplitude_flutter (from `.symlinks/plugins/amplitude_flutter/ios`) was resolved to 0.0.1, which depends on
      Amplitude (= 5.2.1)


You have either:
 * changed the constraints of dependency `Amplitude` inside your development pod `amplitude_flutter`.
   You should run `pod update Amplitude` to apply changes you've made.

Could you help me?

Include setMinTimeBetweenSessionsMillis API

Summary

The API setMinTimeBetweenSessionsMillis should be exposed to the Flutter SDK.

Motivations

By adding this support the Flutter SDK would be more in line with the native support. The Flutter SDK should include all functionality of the native SDK. Unofficial forks of the Amplitude Flutter SDK will lead to increased fragmentation of the ecosystem. Please consider adding this soon.

minSdkVersion 16 is incorrect

Your android plugin defines minSdkVersion 16. However, you include dependency on com.squareup.okhttp3:okhttp:4.2.2 which supports only Android 21+. Running on device with Android api 16 ends up with java.lang.NoClassDefFoundError: java.util.Objects exception as Objects class is not present in the OS.

Crash on iOS

Expected Behavior

App should not crash

Current Behavior

App is crashing

Possible Solution

userId is passed to the parameters map instead of startNewSession

Steps to Reproduce

1. call method setUserId with startNewSession true
2. app crash is observed on iOS

Environment

• SDK Version: 2.2.1
• Flutter Version: 1.22.2
• Device: any iOS device
• Device OS and Version: any iOS device

Expose EventUploadThreshold property to Flutter

It is currently not possible to change EventUploadThreshold with the Flutter API.

Build for iOS fails when Bitcode is enabled

After regenerating the Podfile file using rm ios/Podfile, and trying to build, the build fails. This was done because the tool itself suggested it (maybe some changes to that file in latest Flutter versions).

Running pod install...                                              5,3s

  This can cause issues if your application depends on plugins that do not
  support iOS.

Flutter macOS Support

Description

Hi! Our Flutter app Sharezone is available as an Android, iOS, Web and macOS app. We would love to see macOS support ❤️

Plugin registration crashes with NPE

Expected Behavior

Plugin registers without crashes when app runs in background e.g. Service handle some platform Intent and starts headless FlutterEngine that executes

Current Behavior

Amplitude plugin registration crashes:
Caused by: java.lang.NullPointerException: Attempt to invoke interface method 'void io.flutter.plugin.common.BinaryMessenger.setMessageHandler(java.lang.String, io.flutter.plugin.common.BinaryMessenger$BinaryMessageHandler)' on a null object reference at io.flutter.plugin.common.MethodChannel.setMethodCallHandler(MethodChannel.java:119) at com.amplitude.amplitude_flutter.AmplitudeFlutterPlugin$Companion.registerWith(AmplitudeFlutterPlugin.kt:22) at com.amplitude.amplitude_flutter.AmplitudeFlutterPlugin.registerWith(Unknown Source:2)

Possible Solution

Migrate the plugin to flutter android v2 embedding.

Don't use PluginRegistry.messenger(). According to the docs This registrar is for Flutter's v1 embedding.

Steps to Reproduce

1. Application uses Android v2 plugin embedding.

<application
        android:name=".Application"
        android:icon="@mipmap/ic_launcher"
        ...>

        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />

2. Execute GeneratedPluginRegistrant.registerWith(engine) when an app runs in background e.g. a Service instantiates a FlutterEngine and registers plugins.

Example:

package example

import android.app.IntentService
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugin.common.MethodChannel
import io.flutter.plugins.GeneratedPluginRegistrant
import io.flutter.view.FlutterCallbackInformation
import io.flutter.view.FlutterMain

class ExampleService : IntentService("Example") {
    private var backgroundChannel: MethodChannel? = null

    private var backgroundFlutterEngine: FlutterEngine? = null

    override fun onCreate() {
        super.onCreate()

        if (backgroundFlutterEngine == null) {

            val callbackHandle = retrieveCallbackHandler(....)
            val callbackInfo = try {
                FlutterCallbackInformation.lookupCallbackInformation(callbackHandle)
            } catch (e: IllegalStateException) {
                null
            }

            if (callbackInfo != null) {
                // Create a FlutterEngine which will process the events.
                backgroundFlutterEngine = FlutterEngine(this.applicationContext)

                GeneratedPluginRegistrant.registerWith((backgroundFlutterEngine!!)

                val args = DartExecutor.DartCallback(this.applicationContext.assets, FlutterMain.findAppBundlePath(this.applicationContext)!!, callbackInfo)
                // Start running callback dispatcher code in our background FlutterEngine instance.
                backgroundFlutterEngine!!.dartExecutor.executeDartCallback(args)

                backgroundChannel = MethodChannel(backgroundFlutterEngine!!.dartExecutor.binaryMessenger, "com.example.callback")
            }
        }

    }

    override fun onDestroy() {
        super.onDestroy()
        backgroundFlutterEngine?.destroy()
    }
}

when i remove amplitude plugin and build app all works fine

Set useDynamicConfig for China Mainland?

I use amplitude for my flutter project, by checking the reports we found out we can't get any analytics report from Mainland China, by checking the docs I found this:

But so far Amplitude-Flutter do not expose this useDynamicConfig configuration.

I try to change the iOS code but still the Amplitude.instance still do not have any useDynamicConfig method/props.

Is there any sulutions?

A user ID that comes from another project is set without calling setUserID

Expected Behavior

The user profile should not show a user ID, only Amplitude ID, as setUserID was not called

Current Behavior

User profile shows a user ID that comes from another project linked to a different app with a different bundle ID. Both projects are inside the same organization

Steps to Reproduce

This issue was only reproducible in iOS for me. I installed the apps from TestFlight.
You need to have two applications linked to two different projects within the same organization in Amplitude.

• Application A
• Application B

1. Install Application A from TestFlight
2. Call setUserID within application A with ID 12345
3. Install Application B from TestFlight
4. Do NOT call setUserId in Application B
5. Go to Amplitude's console, project linked to Application B: user profile shows ID 12345(the one set in A), but user ID should be empty

If Application A is uninstalled before installing B (between steps 2 and 3), then the issue doesn't happen and everything works fine

Environment

• SDK Version: 2.2.1
• Flutter Version: 2.0.3
• Device: iPhone SE
• Device OS and Version: iOS 14.4.2

Is there a way to record the time a user is in specific page?

For example, I have a home page. I want to record the period of time (maybe in seconds or minutes) that a user stays on this page. Is there a function to do so using amplitude? I couldn't find a related function in the document so i'm wondering if i missed some information. Thank you.
