Answer 1

Try wrapping any or both children of your row with an Expanded widget

Wrapping only your Text widget with an Expanded widget will be enough to solve your error.

   Column(
      children: [
        Row(
          mainAxisAlignment: MainAxisAlignment.spaceBetween,
          children: [
            Expanded(
              child: Text(
                'Cart().freeDeliveryString',
                style: Theme.of(context).textTheme.headline4,
              ),
            ),
            ElevatedButton(
              onPressed: () {
                Navigator.pushNamed(context, '/');
              },
              style: ElevatedButton.styleFrom(
                primary: Colors.black,
                shape: RoundedRectangleBorder(),
                elevation: 0,
              ),
              child: Text(
                'Add More İtems',
                style: Theme.of(context).textTheme.headline4!.copyWith(
                      color: Colors.white,
                    ),
              ),
            ),
          ],
        ),
      ],
    );
