applicationUserName property

String? applicationUserName
final

An opaque id for the user's account that's unique to your app. (Optional)

Used to help the store detect irregular activity. Do not pass in a clear text, your developer ID, the user’s Apple ID, or the user's Google ID for this field. For example, you can use a one-way hash of the user’s account name on your server.

Implementation

final String? applicationUserName;
