logOut static method
Logs out the Purchases client, clearing the saved appUserID. This will generate a random user id and save it in the cache.
Returns a CustomerInfo
object, or throws a PlatformException if there
was a problem restoring transactions or if the method is called while the
current user is anonymous.
Implementation
static Future<CustomerInfo> logOut() async {
final result = await _channel.invokeMethod('logOut');
return CustomerInfo.fromJson(Map<String, dynamic>.from(result));
}
