publicKeyFromAddress function
Converts an address to a public key.
Takes an address as input and returns the corresponding public key as a list of integers. The address is decoded using the Keyring library, and then the decoded public key is returned.
Implementation
List<int> publicKeyFromAddress(String address) {
final keyring = Keyring();
final decodedPublicKey = keyring.decodeAddress(address);
return decodedPublicKey.toList();
}
