Faq
Why is Flutter so fast?
Flutter is fast because it compiles to native code and uses its own rendering engine to draw widgets directly, eliminating the JavaScript bridge.
Is Flutter good for beginners?
Yes, Flutter is beginner-friendly due to its simple widget system, hot reload, and strong documentation.
Does Flutter work for web?
Yes, Flutter supports web with the same codebase, though performance varies depending on complexity.
Is Flutter better than React Native?
Flutter is generally more consistent and performant due to its rendering engine, while React Native relies on native components and bridges.
