Can you describe the main levels of Flutter architecture and their functions?

Main levels of Flutter architecture and their functions:

1. Framework

   • Written in Dart.
   • Contains widgets that describe the interface and application logic.
   • Allows for declarative UI creation.

2. Engine

   • Written in C++.
   • Responsible for rendering, input handling, and access to platform APIs.
   • Uses Skia for graphics rendering.

3. Embedder

   • Platform-dependent code (e.g., for Android, iOS, Windows).
   • Responsible for integrating the engine with the OS, event handling, and window creation.

This architecture enables Flutter to create high-performance cross-platform applications with a unified UI codebase.
