Implementation

@override
void run() async {
  final googleVision = await GoogleVision.withJwtFile(
      globalResults!['credential-file'],
      'https://www.googleapis.com/auth/cloud-vision');

  final imageFile = File(argResults!['image-file']).readAsBytesSync();

  final aspectRatios = argResults?['aspect-ratios'] == null
      ? null
      : argResults!['aspect-ratios']
          .toString()
          .split(',')
          .map((aspectRatio) => double.parse(aspectRatio))
          .toList();

  final requests = AnnotationRequests(requests: [
    AnnotationRequest(
      jsonImage: JsonImage(byteBuffer: imageFile.buffer),
      features: [Feature(type: AnnotationType.cropHints)],
      imageContext: aspectRatios != null
          ? ImageContext(

            )
          : null,
