User Input and Program Output

This is the main feature of Runnable.

Runnable does not directly provide a coding environment on a mobile device. Instead, it requires an internet connection to send user input to a backend server which evaluates the code and returns the output. Information on the backend can be found at https://github.com/team-stack-underflow/runnable-backend.

We use a WebSocket channel to communicate with the backend, and a Stream class to receive data and update the frontend. The specifications of the messages sent and received can be found here.
