From Text to Program: Exploring an Interpreted Language with Flutter Web

Ever wondered what really happens between the moment you type code and the moment it runs? This talk takes you on a journey **from raw text to a running program**, showing how an interpreted language works under the hood — all inside your browser. Using **Flutter Web**, we’ll build and explore an interactive environment that visualizes the key stages of interpretation: reading source text, parsing it into structure, and executing it step by step. Along the way, we’ll uncover how interpreters make sense of code, how runtime behavior emerges from simple rules, and why this process is both elegant and surprisingly accessible. Whether you’re curious about language design, enjoy visualizing abstract concepts, or just love seeing code come alive, this session will demystify interpreters and showcase how **Flutter Web** can turn them into powerful learning tools. We will be looking into this web app: https://hereket.com/tiny/interpreter-debugger/
