Can you explain the technical essence of the Flutter framework?

Flutter is a UI framework from Google for building cross-platform applications with a single codebase in Dart.

Technically, Flutter works as follows:

• It uses its own rendering engine (Skia), which draws the interface directly on a canvas, bypassing native platform components.
• The application consists of widgets that describe the structure and appearance of the UI.
• Flutter compiles Dart code into native machine code (AOT compilation), ensuring high performance.
• It provides a fast development cycle thanks to the hot reload feature, which allows instant viewing of changes.

Thus, Flutter enables the creation of beautiful and high-performance applications for iOS, Android, and other platforms using a single language and framework.
