getter/setter pair

Methods

balanceOfToken(String caller, String tokenContractAddress) → Future<BigInt>

call(String caller, Contract contract, String funcName, List funcParams, String to, {BigInt? value, int gas = 0, String? gasPayer, String block = "best"}) → Future<Map>

Call a contract method (read-only). This is a single transaction, single clause call. This WON'T create ANY change on blockchain. Only emulation happens. If function has any return value, it will be included in "decoded" field

callMulti(String caller, List<Clause> clauses, {int gas = 0, String? gasPayer, String block = "best"}) → Future<List<Map>>

Call a contract method (read-only). This is a single transaction, multi-clause call. This WON'T create ANY change on blockchain. Only emulation happens. If the called functions has any return value, it will be included in "decoded" field

clause(Contract contract, String funcName, List funcParams, String to, {BigInt? value}) → RClause

There are two types of calls:

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

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

emulate(Map body, {String block = 'best'}) → Future<List<Map>>

Upload a tx body for emulation, Get a list of execution responses (as the tx has multiple clauses).

emulateTx(String address, Map txBody, {String block = "best", String? gasPayer}) → Future<List<Map>>

Emulate the execution of a transaction.adress address of caller, txBody Tx body to be emulated, block Target at which block? by default "best",

getAccount(String address, {String block = 'best'}) → Future<Map>

Takes a address address and returns te account status as a json

getBlock({String block = 'best', bool expanded = false}) → Future<Map>

Returns block as a Map. block enter block id or number, expanded returned block data should be expanded

getChainTag() → Future<int>

returns chaintag

getTransaction(String transactionId) → Future<Map>

Get transaction data of transaction with id transactionId

getTransactionReceipt(String transactionId) → Future<Map?>

get transaction recipt of transaction with id transactionId

getVetBalance(String address) → Future<BigInt>

returns VET blance in VEI

getVthoBalance(String address) → Future<BigInt>

returns the VTHO balance in Wei

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

postTransaction(String raw) → Future<Map>

Post a new transaction with raw payload raw

replayTx(String txId) → Future<List<Map>>

Use the emulate function to replay the tx softly (for debug) Usually when you replay the tx to see what's wrong.

ticker() → Stream<Map>

stream output of best block

toString() → String

A string representation of this object.

inherited

transact(Wallet wallet, Contract contract, String funcName, List funcParams, String to, {BigInt? value, int expiration = 32, int gasPriceCoef = 0, int gas = 0, String? dependsOn, bool force = false, Wallet? gasPayer}) → Future<Map>

transactMulti(Wallet wallet, List<Clause> clauses, {int gasPriceCoef = 0, int gas = 0, String? dependsOn, int expiration = 32, bool force = false, Wallet? gasPayer}) → dynamic

transferToken(Wallet wallet, String to, String tokenContractAddress, [BigInt? amountInWei, Wallet? gasPayer]) → Future<Map>

transferVet(Wallet wallet, String to, {BigInt? value, Wallet? gasPayer}) → Future<Map>

Convenient function: do a pure VET transfer Parameters: to : Address of the receiver, value : optional Amount of VET to transfer in Wei, by default 0

transferVtho(Wallet wallet, String to, [BigInt? vthoInWei, Wallet? gasPayer]) → Future<Map>

waitForTxReceipt(String txId, {int timeout = 20}) → Future<Map?>

Wait for tx receipt, for several seconds Returns the receipt or Null

Operators

operator ==(Object other) → bool

The equality operator.
