Exampleĭemonstrate enumerating Bluetooth devices These examples use the Win32 API for all UI display and do not require Flutter. The package includes a number of examples in the example subdirectory. This example demonstrates creating a Win32 window and responding to common messages such as WM_PAINT through a WindowProc callback function.ĭart compile exe example\hello.dart -o example\bin\hello.exeįor more information on working with the Win32 library from Dart, consult the documentation, in particular the sections on string manipulation and COM objects. Many more samples can be found in the example\ subdirectory, along with a test suite in the test\ subdirectory that shows other API calls.Ī good starting point is hello.dart.

Or filepicker_windows, which provides a modern Windows file picker for Flutter: You might even build a package that depends upon it, like dart_console, which enables advanced console manipulation:
Or even, perhaps, a fully-fledged game using GDI: You could even use it to build a traditional Win32 app, written purely in Dart, that could have come straight out of a classic Charles Petzold book on programming Windows apps: You could use it to build a Windows app with Flutter that relies on Win32 APIs: Or access system information that is not exposed directly by the Dart framework libraries: You could use it to call a Win32 API like EnumFontFamiliesEx to enumerate all locally-installed fonts: This package lets you write apps that use the Windows API directly from Dart, by wrapping common Win32, COM and Windows Runtime APIs using Dart FFI. A good example of that is filepicker_windows, which offers a common item dialog suitable for incorporation into an existing Flutter app. Other Dart packages may build on these primitives to provide a friendly API for Dart and Flutter developers. The goal is to provide high familiarity to an existing Win32 developer. In addition to exposing the APIs themselves, this package offers a variety of instructive examples for more complex FFI usage scenarios.īy design, this package provides minimal modifications to the Win32 API to support Dart idioms.
#THE MODULE MYCOMOBJECT.DLL FAILED TO LOAD. CODE#
A package that wraps some of the most common Win32 API calls using FFI to make them accessible to Dart code without requiring a C compiler or the Windows SDK.
