About This Article
Flutter developers building web apps faced a challenge. They needed to handle different screen sizes and input methods, which meant using different UI patterns than what worked for mobile.
Flutter 2 added dynamic layout constraints that let developers switch between single-column and two-column layouts based on screen size. It also introduced web-specific widgets like Scrollbar and built-in support for keyboard shortcuts and mouse hover states.
Now developers can use the same codebase for iOS, Android, and web. The UI automatically adapts to how each platform works without needing to build separate applications.
