title: Flutter (mailer package): mailing from within the app. not receiving mail
body: <p>I am working on an app in flutter, and I would like to have a "give feedback option". this form consists of 1 text field where the message is typed, and 1 button to submit and sent the feedback. </p>
  
  <p>I am currently using the mailer(1) dart package to do this for me, but so far I have not been able to send and receive a mail in my inbox.  </p>
  
  <p>I have used flutter_mailer and mailer, both without any success. I followed instructions and tried to do the same as the example, but I can not get it working.  </p>
  
  <p>the show code is the method to handle the email.</p>
  
  <pre><code>void sendEmail(String message) async {
    _isLoading = true;
    notifyListeners();
  
    print(message);
    String username = 'matthijs******@gmail.com';
    String password = '******';
  
    final SmtpServer server = gmail(username, password);
    final feedbackMessage = new Message()
    ..from = new Address(username, _authUser.email)
    ..recipients.add('m.dethmers2@hotmail.nl')
    ..ccRecipients.addAll([_authUser.email])
    ..subject = 'Feedback from ${_authUser.id} ${new DateTime.now()}'
    ..text = message
    ..html = "&lt;h1&gt;Test&lt;/h1&gt;\n&lt;p&gt;message&lt;/p&gt;";
  
  final sendReports = await send(feedbackMessage, server, timeout: 
  Duration(seconds: 15));
  
  _isLoading = false;
  notifyListeners();
  print('email send');
  </code></pre>
  
  <p>}</p>
