The official Flutter documentation can be found here.

After color.value is deprecated in Flutter 2.17 how do you get HEX value of a color?

Since color.value is deprecated in Flutter 2.17,
Colors.red.value, gives 'value' is deprecated and shouldn't be used. Use component accessors like .r or .g..
How do you get HEX value of a color? Not only green, red or blue values but HEX value?

 int get value {
    return _floatToInt8(a) << 24 |
        _floatToInt8(r) << 16 |
        _floatToInt8(g) << 8 |
        _floatToInt8(b) << 0;
  }

Should we now write this depricated method ourselves or is there better way?

    There will be a replacement method toARGB32() in the next version. Until then you can use the deprecated getter or re-implement it. I would just wait until toARGB32() makes it into the stable Flutter version.

    String rgbToHex(Color color) {
  return '${color.red.toRadixString(16).padLeft(2, '0')}${color.green.toRadixString(16).padLeft(2, '0')}${color.blue.toRadixString(16).padLeft(2, '0')}';
}
