Functions
address (PublicKey publicKey → String
Generate massa address from a given public key publicKey
asHexString (List <int bytes → String
Converts list of bytes as hex string
base58Decode (String data → Uint8List
decodes given data using base58 check decode
base58Encode (Uint8List data → String
base58Encode encodes the input string into base58 check encode
