Implementation

bool isAccount(
    {AccountRegex regex = AccountRegex.def, int min = 6, max = 18}) {
  String regexStr;
  switch (regex) {
    case AccountRegex.def:
      regexStr = "^[0-9A-Za-z\\W]{6,18}\$";
      break;
    case AccountRegex.charNumNoSpecial:
      regexStr = "^(?![0-9]+\$)(?![a-zA-Z]+\$)[0-9A-Za-z]{6,18}\$";
      break;
    case AccountRegex.charOrNumOrSpecial2:
      regexStr = "^(?![0-9]+\$)(?![a-zA-Z]+\$)[0-9A-Za-z\\W]{6,18}\$";
      break;
    case AccountRegex.charNumSpecial:
      regexStr =
          "^(?![0-9]+\$)(?![a-zA-Z]+\$)(?![0-9a-zA-Z]+\$)(?![0-9\\W]+\$)(?![a-zA-Z\\W]+\$)[0-9A-Za-z\\W]{6,18}\$";
