    );
  }

Everything is contained in one row, the first column will be larger than the second one with the widget Expanded flex :1. In the second column, there's a column widget with that you'll have two rows for your image.

import 'package:flutter/material.dart';

class Home extends StatelessWidget {
  const Home({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        child: Row(
          children: [
            Expanded(
              child: SizedBox(
                child: Image.asset('your large image'),
              ),
              flex: 1,
            ),
            Expanded(
              child: Column(
                children: [
                  Image.asset('your second image'),
                  Image.asset('your third image'),
                ],
              ),
              flex: 0,
            )
          ],
        ),
      ),
    );
  }
}

The key insight is to break the layout into nested rows and/or columns. Check out this example,

import 'package:flutter/material.dart';

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

class App extends StatefulWidget {
  @override
  _AppState createState() => _AppState();
}

class _AppState extends State<App> {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        backgroundColor: Colors.white,
        body: Row(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          crossAxisAlignment: CrossAxisAlignment.stretch,
          children: [
            Expanded(
              child: getContainer(Colors.green),
            ),
            Expanded(
              child: Column(
                mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                crossAxisAlignment: CrossAxisAlignment.stretch,
                children: [
                  Expanded(
                    child: getContainer(Colors.yellow),
                  ),
                  Expanded(
                    child: getContainer(Colors.red),
                  )
                ],
              ),
            ),
          ],
        ),
      ),
    );
  }
}

Widget getContainer(MaterialColor color) =>
    Container(height: 50, width: 50, color: color);
