In-app events and user data

Attention

Please input the value into AirbridgeAttribute.VALUE instead of the existing AirbridgeAttributes.TOTAL_VALUE.

If you're using AirbridgeAttributes.TOTAL_VALUE and defining a value, the logic that AirbridgeAttributes.TOTAL_VALUE overwrites the value has been removed from Flutter SDK v4 onwards.

The function Airbridge.event.trackEvent has been replaced with Airbridge.trackEvent.

Please change the function Airbridge.event.trackEvent to Airbridge.trackEvent following the example code below.

-         label: '...',
-         value: 100,
-         semanticAttributes: {
-             AirbridgeAttributes.QUERY: '...',
-         },
-         customAttributes: {
-             'key1': '...',
-             'key2': '...',
-             'key3': '...',
-         },
-     ));
+ import 'package:airbridge_flutter_sdk/airbridge_flutter_sdk.dart';
+ ...

+     category: 'event',
+     semanticAttributes: {
+         AirbridgeAttribute.ACTION: '...',
+         AirbridgeAttribute.LABEL: '...',
+         AirbridgeAttribute.VALUE: 100,
+         AirbridgeAttribute.QUERY: '...',

+             'key2': '...',
+             'key3': '...',
+     });

Attention

The action , label , value , semanticAttributes values, which are in the second parameter of the Airbridge.event.trackEvent function must be included in the second parameter of the Airbridge.trackEvent function.

The customAttributes value, which is the second parameter of the Airbridge.event.trackEvent function must be included in the third parameter of the Airbridge.trackEvent function.

The functions Airbridge.state.setUser and Airbridge.state.updateUser have been replaced with the Airbridge.setUser related functions. The setUser , updateUser functions, which set user information all at once, are no longer supported.

Update within v3.x

See the major changes in each version of the Flutter SDK.

For Airbridge Apps created after September 4, 2023, an issue where the deep link URL provided in the deep link callback was decoded twice from the content entered in the Airbridge dashboard has been resolved. This issue was found in versions v3.4.2 to v3.4.7.

For Airbridge Apps created after September 4, 2023, the "airbridge_referrer" will no longer be added to the deep link URL provided in the deep link callback.

In the case of an iOS app update, the last calculated SKAdNetwork Conversion Value is finalized. No additional calculations are processed.

  • In versions earlier than v3.4.2, the SKAdNetwork Conversion Value is only calculated for up to 24 hours.

  • This does not affect users who newly installed the app.

deeplink.page has been deprecated. From v3.4.2, we recommend writing code using the deep link domain, abr.ge.

  • deeplink.page will still be supported and functioning for backward compatibility.

v3.4.1 - kotlin

The Kotlin plugin version has been updated to 1.5.21.

v3.4.0 - User privacy

The default value of "trackingAuthorizeTimeout" has been changed to 30 seconds.
