Hello, I'd like to understand what Flutter is and what kind of architecture it has. Could you please provide some information about its widget system and how it affects performance? I'd appreciate an explanation based on basic concepts only.
What is Flutter and how does it work?

When comparing Flutter to React Native, both are used for cross-platform mobile development but their architectures are quite different. While Flutter is based on a **widget system**, React Native uses native components directly. Flutter's widgets are rendered in its own engine (Skia), ensuring a consistent UI across all platforms. React Native, on the other hand, accesses native components through a JavaScript bridge, which means performance can vary depending on the platform.
In terms of performance, Flutter runs **AOT (Ahead-of-Time) compiled code**, typically delivering faster applications. For example, you'll get smoother results in screen scrolling or animations compared to React Native. The widget system is also designed as independent, reusable pieces, making the development process easier.
