<pre><code>   import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  State&lt;StatefulWidget&gt; createState() {
    // TODO: implement createState
    return _MyAppState();
  }
}

class _MyAppState extends State&lt;MyApp&gt; {
  List&lt;String&gt; _bars = ['Olivio bar'];
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          appBar: AppBar(
            title: Text('Drinkzz'),
          ),
          body: Column(
            children: [
              Container(
                margin: EdgeInsets.all(10.0),
                child: RaisedButton(
                  onPressed: () {
                    _bars.add('Riviera Bar');
                  },
                  child: Text('Add new Bar!'),
                ),
              ),
              Column(
                children: _bars
                    .map((element) =&gt; Card(
                          child: Column(
                            children: &lt;Widget&gt;[
                              Image.asset('assets/olivio.jpg'),
                              Text(element)
                            ],
                          ),
                        ))
                    .toList(),
              )
