The Windows embedding was based on the GLFW embedding, which grew organically from a singe-file implementation that used structs to manage all of the important state. It is in the process of being converted to a cleaner object-based architecture, but currently it is a hybrid of objects and structs that have redundant data, making it very prone to errors of forgetting to update pointers in multiple locations. This reduces the remaining structs to only a single pointer to the larger object that manages the responsibilities that handle is associated with, so that there is no need to wire things together in multiple places. For now they continue to exist as projections of the larger objects, but that will be eliminated over time by having an object structure that better reflects the API structure.

Flutter Engine
Flutter is Google's mobile app SDK for crafting high-quality native interfaces in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
The Flutter Engine is a portable runtime for hosting Flutter applications. 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. Most developers will interact with Flutter via the Flutter Framework, which provides a modern, reactive framework, and a rich set of platform, layout and foundation widgets.
If you want to run/contribute to Flutter Web engine, more tooling can be found at felt. This is a tool written to make web engine development experience easy.
If you are new to Flutter, then you will find more general information on the Flutter project, including tutorials and samples, on our Web site at Flutter.dev. For specific information about Flutter's APIs, consider our API reference which can be found at the docs.flutter.dev.
Flutter is a fully open source project, and we welcome contributions. Information on how to get started can be found at our contributor guide.
