使用Flatter和web3dart创建智能合约

我目前正试图与Flatter和web3dart建立一个智能合约。我能够阅读abi创建的智能合同。但是我找不到一个方法，去创造一个新的

阅读很简单：

var ticketABI = ContractABI.parseFromJSON(_TICKET_ABI_EXTRACT, "Ticket");

var ticketContract = new DeployedContract(ticketABI, new EthereumAddress(_TICKET_ADDRESS), ethClient, credentials);

var getTicketCreator = ticketContract.findFunctionsByName("getTicketInformation").first;

var ticketResponse = await new Transaction(keys: credentials, maximumGas: 0)
          .prepareForCall(ticketContract, getTicketCreator, [])
          .call(ethClient);

var ticket = new Ticket.fromResponse(ticketResponse);

但我不知道如何创建新的智能合约

有人知道怎么做吗

谢谢

web3dart目前不支持创建新的智能合约
