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('Delete List Item Example'),
        ),
        body: ListExample(),
      ),
    );
  }

class ListExample extends StatefulWidget {
  @override
  _ListExampleState createState() => _ListExampleState();
}

class _ListExampleState extends State<ListExample> {
  List<String> items = ['Item 1', 'Item 2', 'Item 3'];

  void deleteItem(int index) {
    setState(() {
      items.removeAt(index);
    });
  }

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemCount: items.length,
      itemBuilder: (context, index) {
        return ListTile(
          leading: Icon(Icons.delete),
          title: Text(items[index]),
          onTap: () {
            deleteItem(index);
          },
        );
      },
