encodeKey method

@override String encodeKey(List<int> pubKey, [ Map<String, dynamic> kwargs = const {} ])

Encodes a public key into a Substrate address.

This method takes a public key as a List

Parameters:

• pubKey: The public key to be encoded as a Substrate address.
• kwargs: Optional keyword arguments (e.g., 'ss58_format') for customization.

Returns: A String representing the Substrate address encoded from the provided public key.

Throws:

• FormatException if the provided SS58 format is invalid or if the public key is not a valid sr25519 key.

Implementation

@override
String encodeKey(List<int> pubKey, [Map<String, dynamic> kwargs = const {}]) {
  AddrKeyValidator.validateAddressArgs<int>(kwargs, "ss58_format");
  final int ss58Format = kwargs["ss58_format"];
  List<int> pubBytes = pubKey;
  try {
    AddrKeyValidator.validateAndGetSr25519Key(pubBytes);
  } catch (e) {
    final pub = AddrKeyValidator.validateAndGetEd25519Key(pubKey);
    pubBytes = pub.compressed.sublist(1);
  }
  return SS58Encoder.encode(pubBytes, ss58Format);
}
