This Flutter plugin allows you to display ios tracking authorization dialogue and request permission to collect data.
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.
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.
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>
Google recommends that you should be using Google Mobile Ads SDK 7.64.0 or higher. The Google Mobile Ads SDK supports conversion tracking using Apple's SKAdNetwork, which means Google is able to attribute an app install even when IDFA is unavailable. To enable this functionality, you will need to update the SKAdNetworkItems key with an additional dictionary in your Info.plist.
<key>SKAdNetworkItems</key> <array> <dict> <key>SKAdNetworkIdentifier</key> <string>cstr6suwn9.skadnetwork</string> </dict> </array>
// 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. Until a user grants authorization, the UUID returned will be all zeros: 00000000-0000-0000-0000-000000000000. Also note, the advertisingIdentifier will be all zeros in the Simulator, regardless of the tracking authorization status.
final uuid = await AppTrackingTransparency.getAdvertisingIdentifier();
To use this plugin you should compile your project using XCode 12 and run your app on an ios 14 device.
Google (admob) recommends implementing an explainer message that appears to users immediately before the consent dialogue. For additional info on this topic please refer to this article: https://support.google.com/admob/answer/9997589?hl=en
