ColorToHex(Color).tostring() dont returns the hex code

[visign3d]

var string hexcode = ColorToHex(HexColor('#460000')).toString();
Expected: '#460000'
  Actual: 'Color(0xff460000)'

Ran across this issue and wrote my own helper function to get around it. Thought I'd share here in case anyone else found it useful.

String colorToHexCode(Color color, {ignoreTransparency = false}) {
  // takes in a number from 0-255 and converts it to the equivalent Hex value
  String rgbValueToHexValue(int num) {
    assert(num <= 255 && num >= 0);
    if (num == 0) {
      return "00";
    }
    const hexChars = "0123456789ABCDEF";
    final val = (num / 16);
    final firstVal = val.floor().toInt();
    final secondVal = (val.remainder(firstVal) * 16).toInt();
    return "${hexChars[firstVal]}${hexChars[secondVal]}";
  }

  var result =
      "#${rgbValueToHexValue(color.red)}${rgbValueToHexValue(color.green)}${rgbValueToHexValue(color.blue)}";
  if (color.opacity < 1.0 && !ignoreTransparency) {
    final numVal = (255 * color.opacity).round();
    result += rgbValueToHexValue(numVal);
    return result;
  }
  return result;
}
