Flutter plugin to support iOS and Android Sources at https://segment.com.


  1. Import flutter-segment
  2. Setup your Android and iOS Sources as described at Segment.com and generate your write keys
  3. Android: Add your write key to AndroidManifest Meta Data:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    <!-- io.flutter.app.FlutterApplication is an android.app.Application that
         calls FlutterMain.startInitialization(this); in its onCreate method.
         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->
            <!-- This keeps the window background of the activity showing
                 until Flutter renders its first frame. It can be removed if
                 there is no splash screen (such as the default splash screen
                 defined in @style/LaunchTheme). -->
                android:value="true" />
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
        <meta-data android:name="com.claimsforce.segment.WRITE_KEY" android:value="<YOUR_WRITE_KEY_GOES_HERE>" />
  1. iOS: Add your write key to Info.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

  1. Start tracking events
                eventName: 'TestEvent',
                properties: {
                  'price': 12.22,
                  'product': 'TestProduct',

Sending device tokens for push notifications

Segment integrates with 3rd parties that allow sending push notifications. In order to do that you will need to provide it with the device token - which can be obtained using one of the several Flutter libraries.

As soon as you obtain the device token, you need to add it to Segment's context and then emit a tracking event named Application Opened or Application Installed. The tracking event is needed because it is the only moment when Segment propagates it to 3rd parties.

Both calls (putDeviceToken and track) can be done sequentially at startup time, given that the token exists. Nonetheless, if you don't want to delay the token propagation and don't mind having an extra Application Opened event in the middle of your app's events, it can be done right away when the token is acquired.

await FlutterSegment.putDeviceToken(token);
/// the token is only propagated when one of two events are called:
/// - Application Installed
/// - Application Opened
await FlutterSegment.track(
	eventName: 'Application Opened'
