CameraFrameProxy class final

Zero-copy proxy for CameraFrame. Extends CameraFrame and overrides every getter to read lazily from native memory — no field is copied at construction time. Because CameraFrameProxy <: CameraFrame, a Stream<CameraFrameProxy> satisfies Stream<CameraFrame> via Dart covariant generics. Native memory is freed via a NativeFinalizer backed by the generated C symbol 'nitro_camera_release_CameraFrame'. Ownership: this proxy owns the generated struct shell. Zero-copy field buffers remain owned by the native implementation and must stay valid until this proxy is released by the finalizer or toDartAndRelease.

Constructors

CameraFrameProxy(Pointer<CameraFrameFfi> _native)

Takes ownership of native. Super fields are zeroed and never read; all getters below are overridden to read from native memory instead. Do NOT call malloc.free on the struct shell after passing it here, and do not free zero-copy field buffers while the proxy may be read.

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDartAndRelease() → CameraFrame

Eagerly copies all fields to a plain CameraFrame value, detaches the finalizer, and frees native memory immediately. Use this only when you need an immutable snapshot; for streams prefer consuming the proxy fields lazily then letting it GC. Must not be called more than once.

toNative(Arena arena) → Pointer<CameraFrameFfi>

Available on CameraFrame, provided by the CameraFrameExt extension

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
