deploy method

Future<Map> deploy(Wallet wallet, Contract contract, List<String> paramsTypes, List params, BigInt value,)

Deploy a smart contract to blockchain This is a single clause transaction. paramsTypes Constructor params types, params Constructor params, value send VET in Wei with constructor call

Implementation

Future<Map> deploy(Wallet wallet, Contract contract, List<String> paramsTypes,
    List params, BigInt value) async {
//build transaction body
  Uint8List dataBytes;
  if (paramsTypes.isEmpty) {
    dataBytes = contract.getBytecode();
  } else {
    dataBytes = Uint8List.fromList(
        contract.getBytecode() + buildParams(paramsTypes, params));
  }
  var data = "0x" + bytesToHex(dataBytes);

  var b = await getBlock();
  var txBody = buildTransaction(
    [dev.Clause(null, value.toString(), data)],
    await getChainTag(),
    calcBlockRef(b["id"]),
    calcNonce(),
    gas: 0, // We will estimate the gas later
  );

  var eResponses = await emulateTx(
      wallet.adressString, json.decode(txBody.toJsonString()));
  if (anyEmulateFailed(eResponses)) {
    throw Exception("Tx will revert: $eResponses");
  }

  // Get gas estimation from remote
  var vmGas = readVmGases(eResponses).sum;
  var safeGas = suggestGasForTx(vmGas, json.decode(txBody.toJsonString()));

  // Fill out the gas for user.
  txBody.gas.big = BigInt.from(safeGas);

  Uint8List h = blake2b256([txBody.encode()]);
  Uint8List sig = sign(h, wallet.priv).serialize();
  txBody.signature = sig;
  String raw = '0x' + bytesToHex(txBody.encode());

  //var encodedRaw = calcTxSignedEncoded(wallet, txBody);
  //print(encodedRaw);
