## Instalation
add dependency in pubsec.yaml
from [pub.dartlang.org][pub-repo]:

dependencies:
dart_lut: ^0.0.4
```

import 'dart:io';
import 'package:image/image.dart';
import 'package:dart_lut/src/lut.dart';
```
```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));
}
```
```dart
lut.applyAsStream(image.getBytes()).listen((result) {
print('#${result.toRadixString(16).padLeft(4, '0')}'); //print ARGB value after applying LUT in HEX format
});
```
