CRC8 Algorithm for Dart/Flutter

class CRC8Utils {
  static final CRC8Utils _singleton = new CRC8Utils._internal();

  factory CRC8Utils() {
    return _singleton;

    return new CRC8Utils();
  }

  static var polynomial = 0x07;
  static var mask = 0xff;
  static var table = Uint8List(256);

    for (var idx = 0; idx < table.length; idx++) {
      var c = idx;

        if (c & 0x80 != 0) {
          c = (((c << 1) & mask) ^ polynomial);
        } else {
          c <<= 1;
        }
      }
      table[idx] = c;

  int makeCRC8Int(Uint8List list) {
    var crc8 = initialValue;
    for (var idx = 0; idx < list.length; idx++) {
      crc8 = table[crc8 ^ list[idx]];
    }
    return crc8;
  }
}

// Using
print(CRC8Utils.getInstance().makeCRC8Int(Uint8List.fromList([0x49, 0x4E, 0x46, 0x4F]))); // Result: 88
