Structure

This project is cargo workspace with multiple targets.

flust-winit creates an event loop and a window and interfaces with the flust-engine crate.
flust-engine is the library that make flutter run. It provides a MethodChannel struct to iterop with flutter and dart.

When an engine instance is run, a platform_message_callback is passed to flutter engine using C ffi. A registry listens to flutter MethodChannel calls. Various plugins are registered with the registry using the add_plugin method. When flutter makes a native platform request, the callback is called and processed by a registered plugin.
flust-engine-sys is the crate for ffi with flutter engine C apis. It generates bindings using bindgen.
