NativeHeapUsage class
C heap accounting: what the allocator holds vs what is actually live.
A growing arenaBytes with a flat inUseBytes is allocator residency or fragmentation, not a leak. All fields are 0 where the platform allocator has no equivalent (currently: everything but glibc ≥ 2.33).

Properties
- arenaBytes → int
-
Total bytes the allocator obtained from the OS for its main arena.
final
- freeBytes → int
-
Bytes free inside the arena — held by the process, unused by the program.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- inUseBytes → int
-
Bytes handed out and not yet freed.
final
- isSupported → bool
-
no setter
- mmappedBytes → int
-
Bytes in blocks the allocator mapped separately (returned to the OS on
free, so they do not accumulate).
final
- runtimeType → Type
-
A representation of the runtime type of the object.
