getBlockTransactionCountByHash method

Future<int> getBlockTransactionCountByHash (BigInt blockHash)

Block Transaction Count By Hash The number of transactions in a block from a block matching the given block hash. If the method returns null a count of 0 is returned, this is to distinguish between this and an error.

Implementation

Future<int> getBlockTransactionCountByHash(BigInt blockHash) async {
  if (blockHash == null) {
    throw ArgumentError.notNull(
        "Moac::getBlockTransactionCountByHash - blockHash");
  }
  final String method = MoacRpcMethods.blockTransactionCountByHash;
  final List params = [MoacUtilities.bigIntegerToHex(blockHash)];
  final res = await rpcClient.request(method, params);
  if (res != null && res.containsKey(moacResultKey)) {
    if (res[moacResultKey] != null) {
      return MoacUtilities.hexToInt(res[moacResultKey]);
    } else {
      return 0;
    }
  }
  _processError(method, res);
  return null;
