dart:core tryParse method    DateTime? tryParse(

String formattedString )  Constructs a new DateTime instance based on formattedString. Works like parse except that this function returns null where parse would throw a FormatException. Implementation static DateTime? tryParse(String formattedString) {
  // TODO: Optimize to avoid throwing.
  try {
    return parse(formattedString);
  } on FormatException {
    return null;
  }
}
