code: @NonNull
    public RequestCreator load(@Nullable File file) {
      if (file == null) {
        return new RequestCreator(this, null, 0);
      }
      return load(Uri.fromFile(file));
    }
docs: Start an image request using the specified image file. This is a convenience method for
  calling {@link #load(Uri)}.
  <p>
  Passing {@code null} as a {@code file} will not trigger any request but will set a
  placeholder, if one is specified.
  <p>
  Equivalent to calling {@link #load(Uri) load(Uri.fromFile(file))}.
