The ffigen config has fields that allow you to filter outĪll the functions, structs, enums, etc., that you’re not interested in.įor this example, we’re only interested in AVAudioPlayer,įinal status = player. The resulting file can be millions of lines long. If bindings are generated without any filters, Most Objective-C libraries depend on Apple’s internal libraries, In this example, it is the internal AVAudioPlayer.h header.īy default, ffigen generates bindings for everythingĪnd everything that those bindings depend on in other headers. The entry point is the header file containing the API. The output is the path of the Dart file that ffigen will create. The name is the name of the native library wrapper classĪnd the description will be used in the documentation for that class. language : objc output : ' avf_audio_bindings.dart' headers : entry-points : - ' /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/amework/Headers/AVAudioPlayer.h' So check your version and update Xcode if necessary:įfigen : name : AVFAudio description : Bindings for AVFAudio. This API requires at least macOS SDK 10.7, That uses package:ffigen to generate bindings for You can generate Objective-C headers for Swift APIs,Īllowing dart:ffi and package:ffigen to interact with Swift. To learn more about FFI and interfacing with C code directly, The Dart FFI bindings for a given Objective-C API.

So you can use package:ffigen to automatically generate However, doing so involves a lot of boilerplate code, So it is possible to interact with Objective-C APIs using only dart:ffi. Objective-C is based on and compatible with C, Running on the Dart Native platform, on macOS or iOS,ĭart:ffi allows Dart code to interact with native C APIs. Generating the Objective-C wrapper headerĭart mobile, command-line, and server apps.Callbacks and multithreading limitations.
