  // This is the theme of your application.
  //
  // Try running your application with "flutter run". You'll see the
  // application has a blue toolbar. Then, without quitting the app, try
  // changing the primarySwatch below to Colors.green and then invoke
  // "hot reload" (press "r" in the console where you ran "flutter run",
  // or simply save your changes to "hot reload" in a Flutter IDE).
  // Notice that the counter didn't reset back to zero; the application
  // is not restarted.
}

// This call to setState tells the Flutter framework that something has
// changed in this State, which causes it to rerun the build method below
// so that the display can reflect the updated values. If we changed
// _counter without calling setState(), then the build method would not be
// called again, and so nothing would appear to happen.
class MyHomePage extends StatefulWidget {
  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.

            // arranges them vertically. By default, it sizes itself to fit its
            // children horizontally, and tries to be as tall as its parent.

            // Studio, or the "Toggle Debug Paint" command in Visual Studio Code)

            // how it positions its children. Here we use mainAxisAlignment to
            // center the children vertically; the main axis here is the vertical
            // axis because Columns are vertical (the cross axis would be
