Problem Statement
What are the three main layers in Flutter's architecture?
Explanation
Flutter's architecture consists of the Framework layer written in Dart containing all the widgets, animation, gestures, and material/cupertino libraries that developers interact with directly. This layer provides the reactive framework and widget system that makes Flutter development productive and expressive.
The Engine layer is written in C/C++ and handles low-level rendering using Skia graphics library, text layout, file and network I/O, accessibility, plugin architecture, and Dart runtime. The engine is what gives Flutter its performance, rendering widgets directly to a canvas without going through platform widgets.
The Embedder layer is platform-specific code (Java/Kotlin for Android, Objective-C/Swift for iOS) that integrates Flutter into each platform, handling the app lifecycle, window management, and providing an entry point for the Flutter engine. This layered architecture allows Flutter to maintain consistent behavior across platforms while still accessing platform-specific features.
