A flutter plugin which provides a Dart API for the User Messaging Platform (UMP) SDK, which is the Consent Management Platform (CMP) SDK provided as part of Google's Funding Choices.

Also, see the iabtcf_consent_info package, for reading TCF consent info, made available though Consent Management Platform SDKs, such as UMP. If you have configured Funding Choices to obtain consent for additional purposes for you, the publisher, this package allows you to access that information.

If you're looking for a database solution, check out cbl, another project of mine. It brings Couchbase Lite to standalone Dart and Flutter, with support for:

  • Full-Text Search,
  • Expressive Queries,
  • Data Sync,
  • Change Notifications

and more.


The UMP SDK requires some platform dependent setup.

This basic usage example show how to update the consent info and show the consent form to the user if consent is required:

void updateConsent() async {
  // Make sure to continue with the latest consent info.
  var info = await UserMessagingPlatform.instance.requestConsentInfoUpdate();

  // Show the consent form if consent is required.
  if (info.consentStatus == ConsentStatus.required) {
    // `showConsentForm` returns the latest consent info, after the consent from has been closed.
    info = await UserMessagingPlatform.instance.showConsentForm();

iOS: App Tracking Transparency

You can let the UMP SDK handle the ATT permission request.

If you would like to determine when to show the permission request yourself, you can check the TrackingAuthorizationStatus and requestTrackingAuthorization through this plugin:

void showATTPermissionRequest() async {
  final status = await UserMessagingPlatform.instance.getTrackingAuthorizationStatus();

  if (status == TrackingAuthorizationStatus.notDetermined) {
    await UserMessagingPlatform.instance.requestTrackingAuthorization();
