cameraFrameFromRpcMessage function

CameraFrame cameraFrameFromRpcMessage(Map message, Uint8List bytes)

Reconstructs a CameraFrame from an isolate-request message built by cameraFrameRpcFields and the already-materialized bytes.

The pure-Dart counterpart of each detector's OpenCV decode: the cameraFrameToBgrMat-style step that follows stays per-detector (they own the opencv dependency), this only rebuilds the backend-neutral descriptor.

Implementation

CameraFrame cameraFrameFromRpcMessage(Map message, Uint8List bytes) {
  final int? rotationIndex = message['rotation'] as int?;
  return CameraFrame(
    bytes: bytes,
    width: message['width'] as int,
    height: message['height'] as int,
    strideCols: message['strideCols'] as int,
    conversion: CameraFrameConversion.values[message['conversion'] as int],
    rotation: rotationIndex == null
        ? null
        : CameraFrameRotation.values[rotationIndex],
  );
}
