Methods

getAccounts() → Future<List<String>>: Returns List of accounts the node controls.
getChainId() → Future<int>: Returns chain id in int
isConnected() → bool: Returns true if the provider is connected to the current chain, and false otherwise.
listenerCount([String? eventName]) → int: Returns the number of listeners for the eventName events. If no eventName is provided, the total number of listeners is returned.
listeners(String eventName) → List: Returns the list of Listeners for the eventName events.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
off(String eventName, [Function? listener]) → dynamic: Remove a listener for the eventName event. If no listener is provided, all listeners for eventName are removed.
on(String eventName, Function listener) → dynamic: Add a listener to be triggered for each eventName event.
onAccountsChanged(void listener(List<String> accounts)) → dynamic: Add a listener to be triggered for each accountsChanged event.
once(String eventName, Function listener) → dynamic: Add a listener to be triggered for only the next eventName event, at which time it will be removed.
onChainChanged(void listener(int chainId)) → dynamic: Add a listener to be triggered for each chainChanged event.
onConnect(void listener(ConnectInfo connectInfo)) → dynamic: Add a listener to be triggered for each connect event.
onDisconnect(void listener(ProviderRpcError error)) → dynamic: Add a listener to be triggered for each disconnect event.
onMessage(void listener(String type, dynamic data)) → dynamic: Add a listener to be triggered for each message event type.
removeAllListeners([String? eventName]) → dynamic: Remove all the listeners for the eventName events. If no eventName is provided, all events are removed.
request<T>(String method, [dynamic params]) → Future<T>: Use request to submit RPC requests with method and optionally params to Ethereum via MetaMask or provider that is currently using.
requestAccount() → Future<List<String>>: Request/Enable the accounts from the current environment.
toString() → String: A string representation of this object.
override
walletAddChain({required int chainId, required String chainName, required CurrencyParams nativeCurrency, required List<String> rpcUrls, List<String>? blockExplorerUrls}) → Future<void>: Creates a confirmation asking the user to add the specified chain with chainId, chainName, nativeCurrency, and rpcUrls to MetaMask.
walletSwitchChain(int chainId, [void unrecognizedChainHandler()?]) → Future<void>: Creates a confirmation asking the user to switch to the chain with the specified chainId.
walletWatchAssets({required String address, required String symbol, required int decimals, String? image, String type = 'ERC20'}) → Future<bool>: Requests that the user tracks the token with address, symbol, and decimals in MetaMask, decimals is optional.
