  /// Construct a color from a hex code string, of the format #RRGGBB.
  Color hexToColor(String code) {
    return new Color(int.parse(code.substring(1, 7), radix: 16) + 0xFF000000);
  }

  我最终这样做了：

  hexStringToHexInt(String hex) {
    hex = hex.replaceFirst('#', '');
    hex = hex.length == 6 ? 'ff' + hex : hex;
    int val = int.parse(hex, radix: 16);
    return val;
  }

  一个简单的字符串替换将使用正确的语法：

  String html_colour = '#AAABBCC';
  String fixed_colour = html_colour.replace(new RegExp(r'#'), '0xFF');
  

  应该这样做 .
