Designing the Forgot Password Page for the Flutter Ecommerce App

In this section, we will focus on designing the forgot password page for our Flutter ecommerce app. The forgot password page allows users to reset their forgotten passwords and regain access to their accounts. We will design a simple and user-friendly forgot password page that includes an email input field for users to enter their registered email address. Additionally, we will add a submit button to initiate the password reset process. By following the principles of responsive design, we will ensure that the page layout is optimized for various screen sizes. With an effective and visually appealing forgot password page, we aim to provide a hassle-free and secure password recovery experience for our app users. Let’s proceed with designing the forgot password page to offer a seamless account recovery option in our app.

import 'package:flutter/material.dart';

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

  @override
  State<ForgotPassword> createState() => _ForgotPasswordState();
}

class _ForgotPasswordState extends State<ForgotPassword> {
  // Form Key
  final GlobalKey<FormState> _formKey = GlobalKey<FormState>();

  // TextForm Controller
  TextEditingController emailController = TextEditingController();

  // Form Validation
  bool _validateAndSave() {
    final form = _formKey.currentState;
    if (form!.validate()) {
      form.save();
      return true;
    }
    return false;
  }

  void _validateAndSubmit() {
    if (_validateAndSave()) {
      // TODO: Perform sign-up logic here
    }
  }

  @override
  Widget build(BuildContext context) {
    return WillPopScope(
      onWillPop: () {
        return Future.value(false);
      },
      child: Scaffold(
        appBar: AppBar(
          automaticallyImplyLeading: false,
          title: const Text('Forgot Password'),
        ),
        body: Container(
          padding: const EdgeInsets.all(16.0),
          child: Form(
            key: _formKey,
            child: Column(

              children: <Widget>[
                TextFormField(
                  controller: emailController,
                  decoration: const InputDecoration(labelText: 'Email'),
                  validator: (value) {
                    if (value!.isEmpty) {
                      return 'Please enter your email';
                    }
                    return null;
                  },
                  onSaved: (value) => emailController.text = value!,
                ),
                const SizedBox(height: 16.0),
                ElevatedButton(
                  onPressed: _validateAndSubmit,
                  child: const Text('Submit'),
                ),
                const SizedBox(height: 16.0),
                Center(
                  child: GestureDetector(
                    onTap: _navigateToSignIn,
                    child: RichText(
                      text: const TextSpan(
                        text: 'Have an account? ',
                        style: TextStyle(color: Colors.black),
                        children: <TextSpan>[
                          TextSpan(
                            text: 'Sign In',
                            style: TextStyle(
                              fontWeight: FontWeight.bold,
                              color: Colors.blue,
                            ),
                          ),
                        ],
                      ),
                    ),
                  ),
                ),
              ],
            ),
          ),
        ),
      ),
    );
  }

  // Goto SignUp Page
  void _navigateToSignIn() {
    Navigator.pushReplacement(
      context,
      MaterialPageRoute(builder: (context) => const SignIn()),
    );
  }
}
