DiagnosticMallocAllocator class final

A non-zero-initializing TrackingAllocator.

Memory is not zeroed before it is returned. Integrates with the leak tracker to record allocation metadata when leak tracking is enabled.

Platform behavior:

• Windows: uses CoTaskMemAlloc / CoTaskMemFree
• POSIX: uses malloc / free

Obtain an instance via diagnosticMalloc. Do not instantiate directly.

Implemented types

• TrackingAllocator

Available extensions

• AllocatorAlloc
• AllocatorExtensions

Methods

allocate<T extends NativeType>(int byteCount, {int? alignment}) → Pointer<T>

Allocates byteCount bytes of memory on the native heap.

override

Available on Allocator, provided by the AllocatorAlloc extension

Allocates sizeOf<T>() * count bytes of memory using allocate.

free(Pointer<NativeType> pointer) → void

Releases memory allocated on the native heap.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
