Only one-third of mobile developers use cross-platform frameworks or technologies, while the rest use native tools. As Flutter is very popular, it’s a smart choice to use this framework for web app development.

How Does Flutter Web Function?

Using Flutter for web applications is a smart choice as it’s rich in interactive content. Web support for Flutter offers a browser-based delivery model for existing apps. Flutter renders apps in the same manner as it renders iOS and android apps. Developers can even easily convert the project into native code (CSS, JS, HTML) whenever they wish.

You can create a Single Page web app, which has multiple pages. But when you use Flutter for web application, you can convert the web app into the native language which will have one HTML file, that is, index.html. What can you do if you have multiple pages? The answer is simple, you can follow the Stack data structure. Flutter web app is a single page, but it pushes many pages on a single native page.
