Unable to load asset - Flutter

I've a function that receives 2 images: one from image picker and another from a slider , then it supposes to run a ML model and return an output image, but when I call the function, I get an error 'Unable to load asset'

Future ff(String styleImagePath, String originalImagePath) async {
  ImageTransferFacade showtime = ImageTransferFacade();

  var style_image = showtime.loadStyleImage(await '${styleImagePath}');
  var original_image = showtime.loadoriginalImage(await '${originalImagePath}');

  var output_image = showtime.transfer(await original_image, await style_image);
  return output_image;
}

这两个文件都在您的pubspec.yaml<\/code>中吗?
