Hi. It seems that you are running in a web environment. dart:io (that process_run uses) does not run on the web and is only for io applications (mainly desktop). The only solution (that I personally use but sorry not public yet) is having a local server (websocket) running in a terminal or in a flutter application that a web page talks to.
