ffi_helper 5.0.0-alpha

Utilities for Dart's ffi.

1.0.0+

• dropped, shouldn't be used

2.0.0 - 2.0.0+2

• add thin Array wrapper to manage view into contiguous memory
• add Arena class for arena allocation
• add SharedArray for shared (reference counted) memory

2.0.1

• fix subclassing problem of Array

2.1.0

• Array gets a delete() method (just sugar for free(array.ptr))

3.0.0-beta

• use extensions instead of inheritance (otherwise an Array<Uint8> couldn't be passed as an Uint8Array)
• use only NativeType as as generic type parameter, which is much less verbose

3.1.0-beta

• Array.fromList() accepts all Iterable
• Arena also takes a GetView function like Array as constructor argument
• Arena now produces ArrayViews when calling newArray()
• Work on extensibility, meta annotation and documentation
• export utility functions in library utils

3.2.0-beta

• Array only stores Pointer and its length
• Extension method asTypedList() generates and caches view
• General work on API.

3.2.1-beta

• Work on SharedArray

3.2.2-beta

• fix bug! SharedArray and Arena call standard allocator instead of null

3.3.0-beta

• PlatformSpecific contains platform specific functionality for DynamicLibrary, eg. to get the platform specific file extension for dynamic libraries.

3.3.0-beta+1

• update README

4.0.0

• Array is an abstract class
• As a consequence, more dependency injection for classes that take an Array
• SharedArray has less 'questionable' semantics, or rather it now has correct ones.

4.1.0

• Array is a mixin
• ArrayList is a stupid storage class

5.0.0-alpha

Because of Dart 2.12.0 changes to the FFI's API, this package stopped working. At this point, this is only an experiment to figure out how to write some useful utilities for Dart's FFI. The biggest breaking changes are Dart's introduction of Allocator and that the NativeType generic type argument (like in sizeOf<T>()) needs to be known at compile-time.
