app_tracking_transparency #

This Flutter plugin allows you to display ios 14+ tracking authorization dialog and request permission to collect data. Collected data is crucial for ad networks (ie admob) to work efficiently on ios 14+ devices.

Introduction #

Starting in iOS 14, IDFA will be unavailable until an app calls the App Tracking Transparency framework to present the app-tracking authorization request to the end user. If an app does not present this request, the IDFA will automatically be zeroed out which may lead to a significant loss in ad revenue.

This plugin lets you display App Tracking Transparency authorization request and ask for permission.

Usage #

Make sure you update Info.plist file located in ios/Runner directory and add the NSUserTrackingUsageDescription key with a custom message describing your usage.

<key>NSUserTrackingUsageDescription</key>
<string>This identifier will be used to deliver personalized ads to you.</string>

Example #

// Import package
import 'package:app_tracking_transparency/app_tracking_transparency.dart';

// Show tracking authorization dialog and ask for permission
final status = await AppTrackingTransparency.requestTrackingAuthorization();

// Now you can safely initialize admob and start to show ads. Admob should use
// advertising identifier automatically.
// FirebaseAdMob.instance.initialize(...)

You can also get advertising identifier after authorization if you want.

final uuid = await AppTrackingTransparency.getAdvertisingIdentifier();

Notes #

To use this plugin you should compile your project using XCode 12 and run your app on an ios 14 device.
