The SingleChildScrollView widget is a powerful tool that allows you to make any part of your UI scrollable.

When to Use

You should consider using the SingleChildScrollView widget when you have a portion of your UI that might overflow the screen, and you want to ensure that users can scroll through it.

Code

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('SingleChildScrollView Example'),
        ),
        body: SingleChildScrollView(
          child: Column(
            children: <Widget>[
              Container(
                height: 200.0,
                color: Colors.blue,
                child: Center(
                  child: Text(
                    'Header Content',
                    style: TextStyle(
                      color: Colors.white,
                      fontSize: 24.0,
                    ),
                  ),
                ),
              ),
              Container(
                height: 1000.0, // This container's height exceeds the screen height.
                color: Colors.green,
                child: Center(
                  child: Text(
                    'Scrollable Content',
                    style: TextStyle(
                      color: Colors.white,
                      fontSize: 24.0,
                    ),
                  ),
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}
