Hello community, I am making an application in dart that I want to connect with roboflow inference but I am not able to post correctly. Even following [https://docs.roboflow.com/inference/hosted-api](https://docs.roboflow.com/inference/hosted-api)  
I saw a post that it could be because the image is too big, that’s why I used FlutterImageCompress but still can’t post.  
Does anyone know what I could do?

Thank you very much for reading, best regards, Nuria
