Scaffold

sample.packages.flutter.lib.src.material.scaffold.2287.

This example demonstrates how to use showBottomSheet to display a bottom sheet when a user taps a button. It also demonstrates how to close a bottom sheet using the Navigator.

  
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 MyStatelessWidget(),
      ),
    );
  }
}

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

  @override
  Widget build(BuildContext context) {
    return Center(
      child: ElevatedButton(
        child: const Text('showBottomSheet'),
        onPressed: () {
          Scaffold.of(context).showBottomSheet(
            (BuildContext context) {
              return Container(
                height: 200,
                color: Colors.amber,
                child: Center(
                  child: Column(
                    mainAxisAlignment: MainAxisAlignment.center,
                    mainAxisSize: MainAxisSize.min,
                    children: [
                      const Text('BottomSheet'),
                      ElevatedButton(
                        child: const Text('Close BottomSheet'),
                        onPressed: () {
                          Navigator.pop(context);
                        },
                      ),
                    ],
                  ),
                ),
              );
            },
          );
        },
      ),
    );
  }
}
