Things you can do with enough_ascii_art:

• Convert common UTF-8 emoticons to their text-representation with convertEmoticons(..).
• Create FIGlet text banners with renderFiglet(..).

Usage :

  var image = img.decodeImage(File('./example/enough.jpg').readAsBytesSync());
  var asciiImage = convertImage(image, maxWidth: 40, invert: true);
  print('');
  print(asciiImage);
