rlp
rlp #
An Ethereum RLP library for Dart - https://pub.dartlang.org/packages/rlp
The purpose of RLP (Recursive Length Prefix) is to encode arbitrarily nested arrays of binary data, and RLP is the main encoding method used to serialize objects in Ethereum
rlp takes a String, int or List and returns an RLP encoded Uint8List
Usage #
A simple usage example:
import 'package:rlp/rlp.dart';
main() {
var encoded = Rlp.encode(["dog", "cat"]);
print(encoded); // Uint8List [200, 131, 100, 111, 103, 131, 99, 97, 116]

A more complex usage example:
import 'package:convert/convert.dart';
import 'package:pointycastle/digests/keccak.dart';
import 'package:rlp/rlp.dart';
main() {
var sender = Address('0xba52c75764d6f594735dc735be7f1830cdf58ddf');
var nonce = 3515;
var encoded = Rlp.encode([sender, nonce]);
var out = KeccakDigest(256).process(encoded);
var contractAddress = hex.encode(out.sublist(12));
print('Cryptokitties contract address is 0x$contractAddress'); // 0x06012c8cf97bead5deae237070f9587f8e7a266d
