Contract class - flutter_web3 library

Constructors

Contract(String address, dynamic abi, dynamic providerOrSigner): Instantiate Contract object for invoking smart contract method.
factory
Contract.fromProvider(String address, dynamic abi, Provider<_ProviderImpl> provider): Instantiate Contract from provider for read-only contract calls.
factory
Contract.fromSigner(String address, dynamic abi, Signer<_SignerImpl> signer): Instantiate Contract from provider for read-write contract calls.
factory

Properties

address → String: This is the address (or ENS name) the contract was constructed with.
no setter
deployTransaction → Future<TransactionResponse>: If the Contract object is the result of a ContractFactory deployment, this is the transaction which was used to deploy the contract.
no setter
hashCode → int: The hash code for this object.
no setterinherited
impl → _ContractImpl: Internal JS Object, should not be used directly.
finalinherited
interface → Interface: This is the ABI as an Interface.
no setter
isReadOnly → bool: true if connected to Provider, false if connected to Signer.
no setter
provider → Provider<_ProviderImpl>: If a Provider was provided to the constructor, this is that provider. If a Signer was provided that had a Provider, this is that provider.
no setter
resolvedAddress → Future<String>: This is a Future that will resolve to the address this is attached to.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
signer → Signer<_SignerImpl>?: If a Signer was provided to the constructor, this is that signer.
no setter

Methods

attach(String addressOrName) → Contract: Returns a new instance of the Contract attached to addressOrName.
call<T>(String method, [List args = const []]) → Future<T>: Call read-only constant method with args.
connect(dynamic providerOrSigner) → Contract: Returns a new instance of the Contract, but connected to Provider or Signer.
estimateGas(String method, [List args = const [], TransactionOverride? override]) → Future<BigInt>: Returns the estimate units of gas that would be required to execute the method with args and override.
getFilter(String eventName, [List args = const []]) → Filter: Return a filter for eventName, optionally filtering by additional args constraints.
listenerCount([dynamic event]) → int: Returns the number of listeners for the event. If no event is provided, the total number of listeners is returned.
listeners(Object event) → List: Returns the list of Listeners for the event.
multicall<T>(String method, List<List> args, [Multicall? multicall, bool eagerError = false]) → Future<List<T>>: Multicall read-only constant method with args. Will use multiple https call unless multicall is provided.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
off(dynamic event, [Function? listener]) → dynamic: Remove a listener for the event. If no listener is provided, all listeners for event are removed.
on(dynamic event, Function listener) → dynamic: Add a listener to be triggered for each event.
once(dynamic event, Function listener) → dynamic: Add a listener to be triggered for only the next event, at which time it will be removed.
queryFilter(EventFilter<_EventFilterImpl> filter, [dynamic startBlock, dynamic endBlock]) → Future<List<Event>>: Return a List of Log that have been emitted by the Contract by the filter. Optinally constraint from startBlock to endBlock.
removeAllListeners([dynamic event]) → dynamic: Remove all the listeners for the event. If no event is provided, all events are removed.
send(String method, [List args = const [], TransactionOverride? override]) → Future<TransactionResponse>: Send write method with args, override may be include to send the Ether or adjust transaction options.
toString() → String: A string representation of this object.
override

Operators

operator ==(Object other) → bool: The equality operator.
