processCameraImage method

@override Future<Code> processCameraImage(CameraImage image, DecodeParams params)

Reads barcode from the camera

Implementation

@override
Future<Code> processCameraImage(
  CameraImage image,
  DecodeParams params,
) async {
  // The isolate picks single vs. multi decoding from `params.isMultiScan`, so
  // force it to match the method that was called instead of returning a
  // `Codes` that would fail an unrelated cast at the call site.
  final Object? result = await zxingProcessCameraImage(
    image,
    params.isMultiScan ? params.copyWith(isMultiScan: false) : params,
  );
  if (result is! Code) {
    throw StateError('Expected a Code from the decoder, got $result');
  }
  result.source = CodeSource.camera;
  return result;
}
