How to apply HDR fillter to image in flutter

Question

I am trying to add HDR filter effect to image in flutter using photofilters: ^3.0.1 library. In this library HDR filter is not available so I try to make custom.

What I try

class HDRISHFilter extends ColorFilter {
  HDRISHFilter() : super(name: "HDR-ish") {
    subFilters.add(new SaturationSubFilter(0.5));
    subFilters.add(new HueRotationSubFilter(30));
  }
}

Expected output is HDR-ish:
