Implementation

Color? parseDesignColor(dynamic colorValue) {
  if (colorValue == null || colorValue.toString().isEmpty) return null;
  String colorStr = colorValue.toString().trim();

  if (colorStr.startsWith('rgba(')) {
    final match =
        RegExp(r'rgba\((\d+),\s*(\d+),\s*(\d+),\s*([\d.]+)\)')
            .firstMatch(colorStr);
    if (match != null) {
      return Color.fromRGBO(
        int.parse(match.group(1)!),
        int.parse(match.group(2)!),
        int.parse(match.group(3)!),
        double.parse(match.group(4)!),
      );
    }
  }

  if (colorStr.startsWith('#')) {
    colorStr = colorStr.substring(1);
    if (colorStr.length == 6) {
      return Color(int.parse('FF$colorStr', radix: 16));
    } else if (colorStr.length == 8) {
      return Color(int.parse(colorStr, radix: 16));
    }
  }

  return null;
