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-web.flutter-io.cn, at the following location: https://pub-web.flutter-io.cn/packages?q=dependency%3Awin32.
