Hey, sure this is what i use for RSA with PKCS1 padding

static String encrypt(String text, RSAPublicKey pubKey) {
    var cipher = PKCS1Encoding(RSAEngine());
    cipher.init(true, PublicKeyParameter<RSAPublicKey>(pubKey));
    Uint8List output1 = cipher.process(utf8.encode(text));
    return base64Encode(output1);
  }

static String decrypt(String input, RSAPrivateKey privateKey) {
    var cipher = PKCS1Encoding(RSAEngine());
    cipher.init(false, PrivateKeyParameter<RSAPrivateKey>(privateKey));
    Uint8List output = cipher.process(base64Decode(input));
    return utf8.decode(output);
  }
