Efficient way to make container take remaining width in a Row widget in Flutter

I am new to Flutter and was practicing its UI where I came across a situation where I had a list where each list element have an image on the left and some text on right.

Below is my approach to that

child: ListView(
            padding: const EdgeInsets.symmetric(horizontal: 20),
            children: [
            const SizedBox(height: 5),
            Row(
              children: [
                 Container(
                        height: 80,
                        width: 80,
                        decoration: BoxDecoration(
                          borderRadius: BorderRadius.circular(10),
                          image: const DecorationImage(
                            image: NetworkImage('http://images.unsplash.com/photo-1555010133-d883506aedee?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max'),
                            fit: BoxFit.cover
                          )
                        ),
                      ),
                      const SizedBox(width: 10),
                      Container(
                        color: Colors.green,
                        height: 80,
                        width: 280,
                      )
                    ],
                  ),
                ],
              ),

Here I am specifying width individually for both containers which is not an efficient way to do this since phone sizes may vary.
Below is the result for above block of code

I tried specifying crossAxisAlignment: CrossAxisAlignment.stretch to the Row() but it throws an error as below

The following assertion was thrown during performLayout():
BoxConstraints forces an infinite height.

How can I achieve this? Please assist

Thank you

>Solution :

Wrap the widget with an Expanded inside the row:

Row(
  children: [
    ...otherChildren,
    Expanded(
      child: Container(
        color: Colors.green,
        height: 80,
      ),
    ),
  ],
),
