when we build a Flutter app, it creates static web files that can be easily served by a web server like nginx. Think of it like placing a book on a shelf, and nginx is the librarian who knows where to find and share that book when you ask for it. So, nginx doesn't need to understand Flutter code directly. It's designed to handle these static files, making it a friendly host for your Flutter app when people visit it in a web browser. If you have any more questions, please feel free to ask!
