mintAptosSubdomain method

Future mintAptosSubdomain(AptosAccount account, String subdomainName, String domainName, { int? expirationTimestampSeconds, BigInt? maxGasAmount, BigInt? gasUnitPrice, BigInt? expireTimestamp, })

Mint a new Aptos Subdomain.

account AptosAccount the owner of the domain name. subdomainName subdomain name to mint. domainName Aptos domain name to mint under. expirationTimestampSeconds must be set between the domains expiration and the current time. Return the hash of the pending transaction submitted to the API.
