When I first started using the Hugging Face Spaces API in Flutter, I thought it would be a simple POST → GET workflow.
But turns out, the GET request is actually a stream, which means you have to:
Continuously listen to the data
Check if the full response has been received
Accumulate all chunks
Parse the final JSON
That’s a lot of moving parts—especially in Dart where this pattern isn’t as straightforward as in Python or JavaScript.
So, I built hugging_face_chat_gradio 
A package that handles all of this for you:
Just send a message, get a response
No need to worry about streaming, parsing, or JSON handling
Fully documented for easy use
