Implementation

String fromAscii(String stringValue) {
  ArgumentError.checkNotNull(stringValue);

  var hexString = ''; // eslint-disable-line
  for (var i = 0; i < stringValue.length; i++) {
    // eslint-disable-line
    var code = stringValue.codeUnitAt(i);
    var n = hex.encode([code]);
    hexString += n.length < 2 ? "0$n" : n;
  }

  return "0x$hexString";
}
