CameraPlane typedef
A single camera frame plane exposed by a camera plugin.
Structurally identical to YuvPlane. Dart records are compared by shape,
so the two names are interchangeable at call sites. Use CameraPlane when
the plane may be YUV or packed BGRA/RGBA (e.g. passing to
cameraFrameToBgrMat); use YuvPlane for the YUV-specific packYuv420.
Implementation
typedef CameraPlane = ({Uint8List bytes, int rowStride, int pixelStride});
