What technologies and components form the basis of the Flutter framework?

Flutter is a UI framework from Google for cross-platform development of mobile, web, and desktop applications. The core technologies and components of Flutter include:

• Dart — the programming language used to write Flutter applications. Dart is compiled into native code for mobile platforms and into JavaScript for the web.
• Flutter Engine — a engine written in C++ responsible for rendering graphics (using Skia), handling input, and interacting with the platform.
• Widgets — the basic building blocks of UI in Flutter. Everything in Flutter is widgets, which can be combined to create interfaces.
• Framework — a set of libraries in Dart providing tools for building UI, managing state, navigation, and more.

Thus, Flutter combines its own rendering engine with a high-level Dart framework for creating interfaces and application logic.
