Methods
-
accountNextIndex(
String account) → Future< int> - Returns the next valid index (aka nonce) for given account.
-
addLogFilter(
String directives) → Future - Adds the supplied directives to the current log filter
-
addReservedPeer(
String peer) → Future< String?> -
Adds a reserved peer. Returns the empty string or an error. The string
parameter should encode a

Uint8List extrinsic, {BlockHash? at}) → Future< Uint8List> - Dry run an extrinsic at a given block. Return SCALE encoded ApplyExtrinsicResult.
-
health(
) → Future< Health> - Return health status of the node.
-
localListenAddresses(
) → Future< List< String> > - Returns the multi-addresses that the local node is listening on
-
localPeerId(
) → Future< String> - Returns the base58-encoded PeerId of the node.
