What languages and technologies do the layers in Flutter architecture consist of?

The architecture of Flutter consists of several layers, each using different languages and technologies:

• Flutter Framework — written in Dart. It contains widgets, rendering, animations, and UI logic.

• Flutter Engine — implemented in C++. It handles rendering (using Skia), input processing, text, and other low-level tasks.

• Platform-specific Embedder — written in Java/Kotlin for Android and Objective-C/Swift for iOS. This layer facilitates interaction with native APIs and system services.

Thus, Flutter combines Dart for UI and business logic, C++ for high-performance rendering, and native languages for platform integration.
