import 'package:flutter/material.dart';

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

class SliverDecorationExampleApp extends StatelessWidget {
  const SliverDecorationExampleApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: const Text('SliverDecoration Sample')),
        body: const SliverDecorationExample(),
      ),
    );
  }
}

class SliverDecorationExample extends StatelessWidget {
  const SliverDecorationExample({super.key});

  @override
  Widget build(BuildContext context) {
    return CustomScrollView(
      slivers: <Widget>[
        DecoratedSliver(
          decoration: const BoxDecoration(
            gradient: RadialGradient(

              const Text('Goodnight Moon'),
            ]),
          ),
