hi, i try to implent this plugin, but i have this error in the simple_rsa .dart i'm using the same public and private key from your sample. this is my flutter code:

                onPressed: () async {
                  String tmp = "";
                  print('pressed: '+textEditingController.text);
                  try {
                    final tmp = await encryptString(textEditingController.text, PUBLIC_KEY);
                    setState(() {
                      _stringEncoded = tmp;
                    });

                  } catch (e) {
                    print(e);
                  }
                },

this the Run log on android studio:
