  final fileBytes = File(path).readAsBytesSync();

  final data = await readExifFromBytes(fileBytes);

  if (data.isEmpty) {

    print("No EXIF information found");

    return;

  }

  if (data.containsKey('JPEGThumbnail')) {

    print('File has JPEG thumbnail');

    data.remove('JPEGThumbnail');

  }

  if (data.containsKey('TIFFThumbnail')) {

    print('File has TIFF thumbnail');

    data.remove('TIFFThumbnail');

  }

  for (final entry in data.entries) {

    print("${entry.key}: ${entry.value}");

  }

}
