Usage

generic example:

import 'dart:io';

import 'package:image/image.dart';
import 'package:dart_lut/src/lut.dart';

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));
}

lut.applyAsStream(image.getBytes()).listen((result) {
  print('#${result.toRadixString(16).padLeft(4, '0')}'); //print ARGB value after applying LUT in HEX format
});
