Okay, wrap your string with three quote (''' String '''), Add space or new lines what you want base on your expected height.

https://api.dartlang.org/stable/2.5.0/dart-core/String-class.html

                        SweetAlert.show(
                            context,
                            title: '''

            Just show a message

                            ''',
                            subtitle: '''

            Sweet alert is pretty

                                ''',
                            style: SweetAlertStyle.confirm,
                            showCancelButton: true,
                            onPress: (bool isConfirm) {
                            if (isConfirm) {
                                SweetAlert.show(context,
                                    style: SweetAlertStyle.success, title: "Success");
                                // return false to keep dialog
                                return false;
                            }
                            },
                        );

There is no any option according to my assessment for your question. but I think rflutter_alert is the best option to use instead of sweetalert here you can use the width and height to customize it. Hope that will help you. you can add multiple buttons in buttons: [],

import 'package:rflutter_alert/rflutter_alert.dart';
    Alert(
          context: context,
          type: AlertType.error,
          title: "RFLUTTER ALERT",
          desc: "Flutter is more awesome with RFlutter Alert.",
          buttons: [
            DialogButton(
              child: Text(
                "COOL",
                style: TextStyle(color: Colors.white, fontSize: 20),
              ),
              onPressed: () => Navigator.pop(context),
              width: 120,
            )
          ],
        ).show();
