Flutter is an open-source framework created by Google that lets you build beautiful, natively compiled apps — for mobile, web, and desktop — from a single codebase.
Released in 2017, Flutter stands out because it doesn’t rely on native UI components. Instead, it uses its own rendering engine to draw everything from buttons to animations, giving developers full control over every pixel. That’s why Flutter apps often feel slick, consistent, and super responsive — regardless of platform.
It uses a programming language called Dart, which is easy to pick up if you know JavaScript or Java. With Flutter, you write your app once, and it runs on both Android and iOS — and now even on web browsers and desktop systems like Windows or macOS. It’s fast, flexible, and has a killer feature called hot reload — meaning you can see code changes instantly, without restarting your app.
Flutter is used by startups and giants alike (like Google Pay and BMW), and is known for letting designers and devs work closely thanks to its customizable UI system.
