Response from OpenAIStreamChatCompletionModel missing "usage"

[Tryad0]

In the response from OpenAI.instance.chat.createStream() I see everything from official API Reference but not "usage".

Official API from OpenAI Reference:

{ "id": "chatcmpl-123", "object": "chat.completion", "created": 1677652288, "choices": [{ "index": 0, "message": { "role": "assistant", "content": "\n\nHello there, how may I assist you today?", }, "finish_reason": "stop" }], "usage": { "prompt_tokens": 9, "completion_tokens": 12, "total_tokens": 21 } }

Thanks a lot for your work!

Thank you for your note, I guess I might forget to expose it, I will review and fix it.

@anasfik How can I find the usage when using OpenAIStreamChatCompletionModel? I've got 1.9.1 from pub.dev
