How to add a user to a group via dart sdk

Hello! I can't add user to group via dart sdk. Writes that the url must be either "localhost" or "jettaxi.kz". Although my server is running through "jettaxi.kz" what should I do?

TL;DR

User is having trouble adding a user to a group using the Dart SDK. They receive an error message stating that the URL must be either "localhost" or "jettaxi.kz", even though their server is running through "jettaxi.kz". They are seeking guidance on what to do. Solution: One user suggests using `http://localhost` instead of the actual URL to avoid email sending when using an API key. Another user mentions adding `<@480327814164381697>` to the conversation for more feedback. No specific solution is provided in the thread.

Hi , adding @dlohani to this convo for more feedback

you can use http://localhost no email will be sent when using an API key

The group was created normally but with an error? I use id and name, the console says type "List<dynamic>" is not a subtype of type "Map<String, dynamic>". Or do I need to add roles? It is necessary?
