extension HexColor on Color {
/// String is in the format "aabbcc" or "ffaabbcc" with an optional leading "#".
static Color fromHex(String hexString) {
final buffer = StringBuffer();
if (hexString.length == 6 || hexString.length == 7) buffer.write('ff');
buffer.write(hexString.replaceFirst('#', ''));
return Color(int.parse(buffer.toString(), radix: 16));
}
/// Prefixes a hash sign if [leadingHashSign] is set to `true` (default is `true`).
String toHex({bool leadingHashSign = true}) => '${leadingHashSign ? '#' : ''}'
'${alpha.toRadixString(16).padLeft(2, '0')}'
'${red.toRadixString(16).padLeft(2, '0')}'
'${green.toRadixString(16).padLeft(2, '0')}'
