Send email on flutter direct from a form

have you tried to use this package? https://pub.dev/packages/flutter_email_sender

This is a good email sender but this plugins redirects you to gmail app to send an actual email. It works.

   import 'package:flutter/material.dart';
   import 'dart:async';
   import 'package:flutter_email_sender/flutter_email_sender.dart';

   void main() => runApp(MyApp());

  class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
  // TODO: implement build
  return MaterialApp(
  debugShowCheckedModeBanner: false,
  home: Home(),
   );
   }
  }
 class Home extends StatefulWidget {
  @override
  State<StatefulWidget> createState() {
  // TODO: implement createState
  return _HomeState();
  }
 }

class _HomeState extends State<Home> {
var _emailFormKey = GlobalKey<FormState>();
TextEditingController emailController = new TextEditingController();
TextEditingController messageController = new TextEditingController();

@override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
  resizeToAvoidBottomPadding: false,
  appBar: AppBar(
    title: Text("Email sending App"),
  ),
  body: Form(
    key: _emailFormKey,
    child: Column(
      children: <Widget>[
        Container(
          margin: EdgeInsets.only(top: 50.0, left: 15.0, right: 15.0),
          child: TextFormField(
            controller: emailController,
            validator: (value){
              if(value.isEmpty) {
                return "please Enter email";
              }
            },
            decoration: InputDecoration(
                labelText: "Enter email",
                border: OutlineInputBorder(
                    borderSide: BorderSide(
                  color: Colors.red,
                  width: 2.0,
                ))),
          ),
        ),
        Container(
          margin: EdgeInsets.only(top: 15.0, left: 15.0, right: 15.0),
          child: TextFormField(
            controller: messageController,
            validator: (value){
              if(value.isEmpty) {
                return "please Enter message";
              }
            },
            decoration: InputDecoration(
                labelText: "Enter Message",
                border: OutlineInputBorder(
                    borderSide: BorderSide(
                  color: Colors.red,
                  width: 2.0,
                ))),
          ),
        ),
        Container(
          margin: EdgeInsets.only(top: 15.0),
          child: RaisedButton(child: Text("Send"), onPressed: (){
            if(_emailFormKey.currentState.validate()){
              sendMessage();
            }
          }),
        )
      ],
      ),
     ),
     );
    }
   void sendMessage(){
   String inputEmail ;
   String inputMessage;
   Email email ;
   setState(() {
   inputEmail= emailController.text;
   inputMessage = messageController.text;
   if(inputMessage.isNotEmpty&&inputEmail.isNotEmpty) {
       email = Email(
       body: inputMessage,
       subject: 'Email subject',
       recipients: [inputEmail],
     );
     send(email);
    }

   });
  debugPrint('email - > $inputEmail  message -> $inputMessage');

  }
  void send(Email email) async {
  await FlutterEmailSender.send(email);
 }

 }

// please add "flutter_email_sender:" plugin in pubspec.yaml file

Now I have this problem with the email sender:

• flutter_email_sender does not specify a Swift version and none of the targets (Runner) integrating it have the SWIFT_VERSION attribute set. Please contact the author or set the SWIFT_VERSION attribute in at least one of the targets that integrate this pod.
