Throws unless owner is the current NFT owner, or an authorized tokenAddress An address for whom to query . ownerPrivateKey Owner Private key. recieverAddress The address to transfer to . tokenID The identifier for an NFT

balanceOf(String ___contractAdd___, String ___ownerAdd___) → Future<String>

Gets the balanceOf of the specified address. contractAddr The address of the token. ownerAddress The address to query the balance of.

getApproved(BigInt tokenId_, dynamic _tokenAdd_) → Future<String>

isApproved(String __tokenAdd_, String ownerr_Addr, String spender_addr__) → Future<bool>

Query if an address is an authorized operator for another address tokenAddress An address for whom to query . ownerAddress The address which owns the funds. operatorAddress The address that acts on behalf of the owner return True if operatorAddress is an approved operator for ownerAddress, False otherwise

ownerOf(BigInt tokenId, String _tokenAddr) → Future<String>

tokenAddress The address of the token. tokenId The identifier for an NFT. String representing the address of the owner of the NFT .

safetransferFrom(String contractAddres__, String __spenderAddr, String receiver__Address, BigInt token_id_, String Spender_Privatekey, String ownerAddress__) → Future<String>

Transfers the ownership of an NFT from one address to another address This works identically to the other function with an extra data parameter, except this function just sets data to "". tokenAddress An address for whom to query . ownerAddress owner Of The Token . recieverAddress The address to transfer to tokenID : The identifier for an NFT approvedPrivateKey : Approved Address Private key.

setApproveofAll(String owner___PrivateKey, String contract___add, String spender___Add, bool boolValue) → Future<String>

Enable or disable approval for a third party ("operator") to manage all of Owner's assets Emits the ApprovalForAll event. The contract MUST allow multiple operators per owner. token_address An address for whom to query . operatorAddress An address for whoom you want to give to give Approve Status. approvedStatus true if the operator is approved, false to revoke approval ownerPrivateKey PrivateKey Of The Token Owner . tokenId The identifier for an NFT

supportInterface(dynamic interface_id, String tokenAddr__) → Future<String>

Query if a contract implements an interface tokenAddress An address for whom to query . interfaceId The interface identifier true if the contract implements interfaceID and interfaceID is not 0xffffffff, false otherwise .

symbol(String tokenAddress) → Future<String>

Gets the Symbol of the specified address.

tokenByIndex(BigInt index, String _token_Add_) → Future<String>

Enumerate NFTs assigned to an owner tokenAddress An address for whom to query . IndexNO A counter less than totalSupply() The token identifier for the indexth NFT assigned to owner

tokenofOwnerByIndex(BigInt index_, String _token__Add_, String ownerrAddr) → Future<String>

Enumerate NFTs assigned to an owner Throws if index >= balanceOf(owner) or if owner is the zero address, representing invalid NFTs. tokenAddress An address for whom to query . IndexNO A counter less than totalSupply() ownerAddress The address which owns the funds. The token identifier for the indexth NFT assigned to owner

tokenURI(BigInt token_id, String tokenAddr__) → Future<String>
