In-app messages integration

Native in-app messages display automatically on Android and iOS when using Flutter. This article covers different customization options for in-app messages for Flutter.

Analytics

To log analytics using your BrazeInAppMessage, pass the instance into the desired analytics function:

  • logInAppMessageClicked
  • logInAppMessageImpression
  • logInAppMessageButtonClicked (along with the button index)

For example:

1
2
3
4
5
6

// Log a click
braze.logInAppMessageClicked(inAppMessage);
// Log an impression
braze.logInAppMessageImpression(inAppMessage);
// Log button index `0` being clicked
braze.logInAppMessageButtonClicked(inAppMessage, 0);

Disabling automatic display

To disable automatic in-app message display, make these updates in the native layer.

  1. Ensure you are using the automatic integration initializer, which is enabled by default starting in version 2.2.0.
  2. Set the in-app message operation default to DISCARD by adding the following line to your braze.xml file.
1

<string name="com_braze_flutter_automatic_integration_iam_operation">DISCARD</string>

  1. Implement the BrazeInAppMessageUIDelegate delegate as described in our iOS article here.

  2. Update your inAppMessage(_:displayChoiceForMessage:) delegate method to return .discard.

Receiving in-app message data

To receive in-app message data in your Flutter app, the BrazePlugin supports sending in-app message data using Dart Streams.

The BrazeInAppMessage object supports a subset of fields available in the native model objects, including uri, message, header, buttons, extras, and more.

Step 1: Listen for in-app message data in the Dart layer

To receive to the in-app message data in the Dart layer, use the code below to create a StreamSubscription and call braze.subscribeToInAppMessages(). Remember to cancel() the stream subscription when it is no longer needed.

// Create stream subscription
StreamSubscription inAppMessageStreamSubscription;

inAppMessageStreamSubscription = braze.subscribeToInAppMessages((BrazeInAppMessage inAppMessage) {
  // Handle in-app messages
}

// Cancel stream subscription
inAppMessageStreamSubscription.cancel();

For an example, see main.dart in our sample app.

Step 2: Forward in-app message data from the native layer

To receive the data in the Dart layer from step 1, add the following code to forward the in-app message data from the native layers.

The in-app message data is automatically forwarded from the Android layer.

  1. Implement the BrazeInAppMessageUIDelegate delegate as described in our iOS article on core in-app message delegate.

  2. Update your willPresent delegate implementation to call BrazePlugin.process(inAppMessage).

Replaying the callback for in-app messages

To store any in-app messages triggered before the callback is available and replay them after it is set, add the following entry to the customConfigs map when initializing the BrazePlugin:

1

BrazePlugin braze = new BrazePlugin(customConfigs: {replayCallbacksConfigKey: true});

Test displaying a sample in-app message

Follow these steps to test a sample in-app message.

  1. Set an active user in the React application by calling braze.changeUser('your-user-id') method.
  2. Head to the Campaigns page on your dashboard and follow this guide to create a new in-app message campaign.
  3. Compose your test in-app messaging campaign and head over to the Test tab. Add the same user-id as the test user and click Send Test.
  4. Tap the push notification and that should display the in-app message on your device.

A Braze in-app message campaign showing you can add your own user ID as a test recipient to test your in-app message.
