final lut = LUT.fromString(File('example.cube').readAsStringSync());
final isLoaded = await lut
    .awaitLoading()
    .timeout(Duration(milliseconds: 1500), onTimeout: () => false);

if (isLoaded) {
  final image = decodeImage(imageFile.readAsBytesSync());
  var lutedBytes = lut.applySync(image.getBytes());

  var imageLUT = Image.fromBytes(image.width, image.height, lutedBytes);
  var outputFile = File('out.jpg')..writeAsBytesSync(encodeJpg(imageLUT));
