objective_c 3.0.0

A library to access Objective C from Flutter that acts as a support library for package:ffigen.

3.0.0

• Add the following stream-related types to the core package:
  • NSInputStream
  • NSOutputStream
  • NSRunLoop
  • NSStream
  • NSStreamDelegate
  • NSStreamEvent
  • NSStreamStatus
• 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 https://github.com/dart-lang/native/issues/204
• Improve debuggability of memory management errors.
