Installation and Usage #

Add the dependency to your project.

dependencies:
  amplitude_flutter: ^2.0.0

Import the module and use its APIs.

import 'package:amplitude_flutter/amplitude.dart';
import 'package:amplitude_flutter/identify.dart';

class YourClass {
  Future<void> exampleForAmplitude() async {
    // Create the instance
    final Amplitude analytics = Amplitude.getInstance(instanceName: "project");

    // Initialize SDK
    analytics.init(widget.apiKey);

    // Enable COPPA privacy guard. This is useful when you choose not to report sensitive user information.
    analytics.enableCoppaControl();

    // Set user Id
    analytics.setUserId("test_user");

    // Turn on automatic session events
    analytics.trackingSessionEvents(true);

    // Log an event
    analytics.logEvent('MyApp startup', eventProperties: {
      'friend_num': 10,
      'is_heavy_user': true
    });

    // Identify
    final Identify identify1 = Identify()
      ..set('identify_test',
          'identify sent at ${DateTime.now().millisecondsSinceEpoch}')
      ..add('identify_count', 1);
    analytics.identify(identify1);

    // Set group
    analytics.setGroup('orgId', 15);

    // Group identify
    final Identify identify2 = Identify()
      ..set('identify_count', 1);
    analytics.groupIdentify('orgId', '15', identify2);
  }
}

Advertising Id Tracking #

In iOS, to enable Advertising Id tracking, you will need to add AdSupport.framework in your project setting page.

In Android, firstly you need to add com.google.android.gms:play-services-ads as a dependency in your build.gradle. If you use Google Mobile Ads SDK version 17.0.0 above. You need to add AD_MANAGER_APP into your androidmanifest.xml file.

Secondly, since we don't assume user's project will depend on this library, we use reflection to invoke its APIs. So the names of its classes can't be changed since reflection will use original name to find the class. You also need to add exception rules into your proguard-android.txt or proguard-rules.pro.

-keep class com.google.android.gms.ads.** { *; }
