Basic

sample.packages.flutter.lib.src.widgets.basic.1615.

In this example, the image is stretched to fill the entire [Container], which would not happen normally without using FittedBox.

  
import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

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

  static const String _title = 'Flutter Code Sample';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: const Center(
          child: MyStatelessWidget(),
        ),
      ),
    );
  }
}

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

  @override
  Widget build(BuildContext context) {
    return Container(
      height: 400,
      width: 300,
      color: Colors.red,
      child: FittedBox(
        fit: BoxFit.fill,
        child: Image.network(
            'https://flutter.github.io/assets-for-api-docs/assets/widgets/owl-2.jpg'),
      ),
    );
  }
}
