In this tutorial we shall discuss how to create the logout screen of out flutter app.

1. Create The Logout Screen

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class LogoutScreen extends StatefulWidget {
  const LogoutScreen({super.key});

  @override
  State<LogoutScreen> createState() => _LogoutScreenState();
}

class _LogoutScreenState extends State<LogoutScreen> {

  

  @override
  Widget build(BuildContext context) {
    return const Placeholder();
  }
}

2. Now Create The Asynchronous Function

import 'package:shared_preferences/shared_preferences.dart'; 

import '../Home/Home.dart';

Future<void> _logoutUser() async {
    SharedPreferences prefs = await SharedPreferences.getInstance();
    await prefs.remove('email');
    await prefs.remove('password');
    // Redirect to Home screen
    Navigator.pushReplacement(
      context,
      MaterialPageRoute(builder: (context) => Home()),
    );
  }

3. Now Call The Logout Function On Page Load

  @override

    super.initState();
