2.1.0-wip

  • Add UnimplementedOptionalMethodException, which is thrown by the ObjC bindings if an optional method is invoked, and the instance doesn't implement the method.
  • Dispatch all object/block releases to the main thread.
  • Add utils for converting Dart Strings to Objective-C selectors and back.
  • Require Dart 3.4 or later (due to the use of dart:ffi Struct.create by package:ffigen).
  • Breaking change: Return structs from ObjC methods by value instead of taking a struct return pointer.

2.0.0

  • Drop API methods that are deprecated in the oldest versions of iOS and macOS that flutter supports.
  • Added ObjCBlock, which is the new user-facing representation of ObjC blocks.
  • Migrate to ARC (Automatic Reference Counting).
  • Enable ObjC objects and blocks to be sent between isolates.
  • Add autorelease and retainAndAutorelease methods to ObjC objects and blocks.
  • Breaking change: Remove some convenience methods from _ObjCRefHolder: isReleased, release, pointer, and retainAndReturnPointer. Uses of these methods now need to go through .ref. Eg obj.pointer becomes obj.ref.pointer.

1.1.0

  • Add DartProxy, which is an implementation of NSProxy that enables implementing ObjC protocols from Dart. Also adds DartProxyBuilder for constructing DartProxy.
  • Add some extensions methods for NSMutableData.
  • Fix the NSError bindings so that they're not empty.
  • Add ObjCProtocolBuilder, which is an ergonomic wrapper around DartProxyBuilder.
  • Add ObjCProtocolMethod, which contains all the information that ObjCProtocolBuilder needs to implement a method. These objects are created by the ffigen bindings for a protocol.
  • Make all of the code-genned structs and enums public so they can be reused by user bindings.
  • Use package:dart_flutter_team_lints.

1.0.1

  • Mention experimental status in readme.

1.0.0

  • Move sharable code from ffigen's generated code into this package, including ObjCObjectBase, and ObjCBlockBase, as well as the core Objective C runtime functions (except objc_msgSend, which is library specific).
  • Move core ObjC classes such as NSString into this package.
  • Delete Dart functions associated with ObjC closure blocks when the block is destroyed. Fixes #204
  • Improve debuggability of memory management errors.
