  final ed25519 = Ed25519();
  final aliceWand = await ed25519.newKeyExchangeWand();
  final signedMessage = [1,2,3];
  final signature = await aliceWand.sign(signedMessage);
  print('Signature: ${signature.bytes}');
  print('Public key: ${signature.publicKey}');
}

Implementation

Future<Signature> sign(List<int> message);
