                                    ),
                                  ),
                                ),
                              ),
                            ),
                          ],
                        ),

Answer 1

Everything works correctly since your message is sent, except on line message: ' ', you didn't add the message content that should be sent.

The solution is this,

onPressed: () {
               sendEmail(
               email: '',
               message: _messageController.text.trim(),
               name: '',
               subject: '');
     },

I would also suggest you provide fields to fill all the other fields for a better end user experience.
