How to make a dynamic Flutter button with add2calendar package?

Question

New to Flutter. I have this button and on pressed is launching the calendar on device. I want to make this button dynamic as i have more than 20 dates in my model/events.dart list and i want to launch the calendar with the specific date like DateTime('${events.date}') maybe? Is there another solution for this? Vs Code errors is telling me that i should create a getter to solve this. Thoughts?

import 'package:flutter/material.dart';
import 'package:add_2_calendar/add_2_calendar.dart';
import 'package:font_awesome_flutter/font_awesome_flutter.dart';
import 'package:provider/provider.dart';
import '../model/events.dart';

class Calendar extends StatefulWidget {
  @override
  _CalendarState createState() => _CalendarState();
}

class _CalendarState extends State<Calendar> {
  final GlobalKey<ScaffoldState> scaffoldState = GlobalKey();

  @override
  Widget build(BuildContext context) {
    Event event = Event(
      title: '',
      description: '',
      location: '',
      startDate: DateTime.now(),
      endDate: DateTime.now(),
      allDay: false,
    );

    return Row(
      children: <Widget>[
        IconButton(
          icon: Icon(
            FontAwesomeIcons.calendarAlt,
            size: 30.0,
            color: Colors.green,
          ),
          onPressed: () {
            Add2Calendar.addEvent2Cal(event);
          },
        ),
      ],
    );
  }
}

import 'package:flutter/foundation.dart';

class Events {
  final String imagePath,
      title,
      description,
      location,
      duration,
      punchLine1,
      punchLine2,
      address,
      shareB,
      phone,
      fb,
      maps,
      guide,
      date;
  final List categoryIds, galleryImages;

  Events({
    @required this.imagePath,
    @required this.title,

You can use a List<Events> :

In your events.dart

final events = [
  ponteRagogna,
  new Events(...)
];

In your code :

Row(
  children: [
    for (var staticEvent in events)
      IconButton(
        onPressed: () {
         final event = Event(
           title: '',
           description: '',
           location: '',
           startDate: DateTime(staticEvent.date),
           endDate: DateTime(staticEvent.date),
           allDay: false,
         );
         Add2Calendar.addEvent2Cal(event)
        },
      )
  ]
)
