Implementation

final Parser<String> ESC = ((char('\\') & pattern('`\'\\/fnrt')).flatten() |
        (char('\\') & UNICODE).map((value) {
          return String.fromCharCodes(
              [int.parse(value[1].replaceAll('u', ''), radix: 16)]);
        }))
    .map((value) {
  return value == r"\'"
      ? "'"
      : value == r"\`"
          ? '`'
          : jsonDecode('"$value"');
});
