win32 5.0.2

A Dart library for accessing common Win32 APIs using FFI. No C required!

example/README.md

The package includes a number of examples in the example subdirectory, which demonstrate various aspects of invoking Windows APIs, including:

• Invoking C-style APIs, including creating structs and memory management
• Building classic (Win32) desktop UI
• Using callback functions with Win32 APIs
• Invoking COM classes (both IUnknown and IDispatch interface types)
• Integrating Windows code with Flutter

Other examples of packages that use Win32 can be found on pub.dev, at the following location: https://pub.dev/packages?q=dependency%3Awin32.
