Core Concepts & Terminology

FFI (Foreign Function Interface): The dart:ffi library used to bind Dart directly to native C/C++ APIs.

Platform Channel: The asynchronous message-passing system (MethodChannel, BasicMessageChannel) connecting the Dart client (UI) to the host platform (Kotlin/Java, Swift/Objective-C, C++).

Pigeon: A code-generation tool that creates type-safe Platform Channels.

Platform View: A mechanism to embed native UI components (e.g., Android View, iOS UIView) directly into the Flutter widget tree.

JS Interop: The modern, Wasm-compatible approach to interacting with JavaScript and DOM APIs using package:web and dart:js_interop.

Binding to Native C/C++ Code (FFI)

Use FFI to execute high-performance native code or utilize existing C/C++ libraries without the overhead of asynchronous Platform Channels.
