This blog covers how Flutter supports web, mobile and desktop applications from a single codebase. It explains how Flutter’s rendering engine, the use of the Dart language, and widget-driven UI let you share logic and layouts across platforms for Flutter cross-platform development. You’ll also learn how it works on browsers (HTML, CSS, JS compile), on iOS/Android (native-style features) and on Windows/macOS/Linux (keyboard/mouse, file system access). Finally, it highlights when Flutter is a strong choice and when another tool might suit you better.
