Major components of Flutter Architecture are: –

• Dart Platform
  • Flutter apps are written in the Dart language.
  • While writing and debugging an application, Flutter runs in the Dart virtual machine, which features a just-in-time execution engine. This allows for fast compilation times as well as “hot reload”, with which modifications to source files can be injected into a running application.
  • For better performance, release versions of Flutter apps on all platforms use ahead-of-time (AOT) compilation.
• Flutter Engine (Skia Graphics Engine)
  • Flutter’s engine, written primarily in C++, provides low-level rendering support using Google’s Skia graphics library.
  • Additionally, it interfaces with platform-specific SDKs such as those provided by Android and iOS.
  • It implements Flutter’s core libraries, including animation and graphics, file and network I/O, accessibility support, plugin architecture, and a Dart runtime and compile toolchain.
• Foundation Library
  • The Foundation library, written in Dart, provides basic classes and functions that are used to construct applications using Flutter, such as APIs to communicate with the engine.
• Design-Specific Premade Widgets
  • Material Design widgets implement Google’s design language of the same name.
  • Cupertino widgets implement Apple’s iOS Human interface guidelines.
• Flutter Development Tools (SDK)
