How to get Containers to fill available vertical space in a Row?

Question

can anyone help me out?

I'm struggling to figure out how I can get the coloured containers to extend to match the height of the tallest one in their row.

Currently they have no fixed height/width and are wrapped in Expanded widgets to get their dynamic size.

I'd like to keep their responsive sizes if possible. I already have a method in place to switch to a Column instead of a Row once the screen is small enough. Once in a Column I can use width: double.infinity because there is no horizontal scroll..

This is an example of the code used (sorry there's so much!):

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Scrollbar(
        child: CustomScrollView(
          slivers: <Widget>[
            SliverNavBar(),
            SliverList(
              delegate: SliverChildListDelegate(
                [
                  Row(
                    crossAxisAlignment: CrossAxisAlignment.start,
                      children: _homePageContent(),
                     );
                  Footer()
                ],
              ),
            ),
          ],
        ),
      ),
    );
  }
}

_homePageContent() {
  return <Widget>[
    _HomePageInfoBox(
      backgroundColor: accentColor,
      title: 'THIS IS A TITLE',
      body:
          'Lorem ipsum...',
    ),
    _HomePageInfoBox(
      backgroundColor: primaryColorDark,
      title: 'THIS IS A TITLE',
      body:
          'Lorem ipsum....',
    ),
    _HomePageInfoBox(
      backgroundColor: primaryColor,
      title: 'THIS IS A TITLE',
      body:
          'Lorem ipsum...',
    ),
  ];
}

class _HomePageInfoBox extends StatelessWidget {
  const _HomePageInfoBox({
    Key key,
    @required this.title,
    @required this.body,
    @required this.backgroundColor,
  }) : super(key: key);

  final String title;
  final String body;
  final Color backgroundColor;

  @override
  Widget build(BuildContext context) {
    return Expanded(
      Container(
      color: backgroundColor,
      child: Padding(
        padding: const EdgeInsets.all(50),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          mainAxisAlignment: MainAxisAlignment.start,
          children: <Widget>[
            Text(
              title,
              style: TextStyle(
                  color: primaryTextColor,
                  fontSize: 25,
                  fontFamily: 'CoffeeAndTea'),
            ),
            SizedBox(height: 10),
            Text(
              body,
              style: TextStyle(
                  color: primaryTextColor,
                  fontSize: 24,
                  height: 1.4,
                  fontFamily: 'ElegantSans'),
            ),
            SizedBox(height: 20),
            Text(
              "Let's Go!",
              style: TextStyle(
                  color: Colors.white, fontFamily: 'CreamCake', fontSize: 30),
              textAlign: TextAlign.center,
            ),
          ],
        ),
       ),
     ),
    );
  }
}

To adjust row items height to biggest one wrap row of items with IntrinsicHeight widget:

  IntrinsicHeight(
    child:Row(
      crossAxisAlignment: CrossAxisAlignment.stretch,
      children: _homePageContent(),
    ),
  ),

Here is dartpad demo.
