win32 6.0.0

Call common Windows APIs directly from Dart using FFI.

example/README.md

Examples

This package includes a comprehensive set of examples in the examples directory, demonstrating practical, idiomatic use of Windows APIs from Dart.

What you will find

Across the examples, you will see how to:

• Invoke C-style Win32 APIs, including struct layout, pointer management, and lifetime control
• Build classic Win32 desktop applications using user32, gdi32, and common dialogs
• Register and use native callback functions safely from Dart
• Create and consume COM objects via both IUnknown and IDispatch
• Integrate low-level Windows APIs into Flutter desktop applications

For real-world usage beyond these samples, explore packages on that depend on package:win32.
