fromUri method

Future<KeyPair> fromUri(String uri, { String? password, bool addToPairs = false, KeyPairType? keyPairType, })

Create a new KeyPair from a BIP39 mnemonic and optionally add it to the keyring.

This method generates a key pair from the provided uri.

• uri: The BIP39 mnemonic phrase used to derive the key pair.
• addToPairs: If set to true, the key pair will be added to the keyring, defaults to false.

Example:

final keyring = Keyring();
// final uri = '//Alice';
final keyPair = await keyring.fromUri(uri);

Implementation

Future<KeyPair> fromUri(
  String uri, {
  String? password,
  bool addToPairs = false,
  KeyPairType? keyPairType,
}) async {
  late KeyPair pair;

  switch (keyPairType ?? this.keyPairType) {
    case KeyPairType.ed25519:
      pair = await KeyPair.ed25519.fromUri(uri, password);
      break;
    case KeyPairType.ecdsa:
      pair = await KeyPair.ecdsa.fromUri(uri, password);
      break;
    default:
      pair = await KeyPair.sr25519.fromUri(uri, password);
  }

  if (addToPairs) {
    pairs.add(pair);
  }
  return pair;
}
