ECDSAInputSignature.fromBytes constructor

ECDSAInputSignature.fromBytes(Uint8List bytes)

Implementation

  if (bytes.isEmpty) throw InvalidInputSignature();

  } on InvalidECDSASignature {
    throw InvalidInputSignature();
  }

  return ECDSAInputSignature(sig, _hashTypeFromValueWithCheck(bytes.last));
