0.2.0 – 2025-10-13

Added

• RAII memory management for DartMetal.

  • RAII class for automatic memory allocation and cleanup with finalizers.

  • RAIITyped helper for type-safe allocations of SizedNativeType (Uint8, Uint16, Uint32, Int32, Float, Double).

  • Methods:

    • allocate / allocateTyped
    • clone (deep copy)
    • move (transfer ownership)
    • withScoped / withScopedTyped (automatic cleanup in a scoped block)

  • Access to raw memory via ptr and typed pointer via typedPtr.

Fixed

• Resolved sizeOf<T>() compile-time error for generic types by mapping SizedNativeType to concrete sizes internally.

Improved

• Memory safety: typed RAII allocations prevent misaligned pointer casts.
• Scoped allocations now automatically free memory when exiting the scope.

Notes

• All RAII allocations are automatically finalized on garbage collection but can be manually freed with free().
• Deep copies (clone) and ownership moves (move) fully support typed memory allocations.
