Plain Login Page Built Using Flutter Code

To create a plain login page in Flutter, you can use the TextField and FlatButton widgets to create input fields for the user’s email and password, and a button for the user to submit their login credentials.

Here is an example of a simple login page that uses these widgets:

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: LoginPage(),
    );
  }
}

class LoginPage extends StatefulWidget {
  @override
  _LoginPageState createState() => _LoginPageState();
}

class _LoginPageState extends State<LoginPage> {
  String _email;
  String _password;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          Container(
            padding: EdgeInsets.all(16),
            child: TextField(
              decoration: InputDecoration(
                labelText: 'Email',
                border: OutlineInputBorder(),
              ),
              onChanged: (value) {
                setState(() {
                  _email = value;
                });
              },
            ),
          ),
          Container(
            padding: EdgeInsets.all(16),
            child: TextField(
              obscureText: true,
              decoration: InputDecoration(
                labelText: 'Password',
                border: OutlineInputBorder(),
              ),
              onChanged: (value) {
                setState(() {
                  _password = value;
                });
              },
            ),
          ),
          Container(
            padding: EdgeInsets.symmetric(vertical: 16),
            child: FlatButton(
              onPressed: () {
                // Submit login credentials...
              },
              child: Text(
                'Log In',
                style: TextStyle(
                  color: Colors.white,
                ),
              ),
              color: Colors.blue,
            ),
          ),
        ],
      ),
    );
  }
}

In the bustling world of app development, crafting an elegant login page is essential. Flutter, a powerful UI toolkit, offers a variety of widgets to achieve that goal. Let me introduce you to a simple, yet effective LoginPage class. It inherits the StatefulWidget class, allowing it to adapt as users interact.

The core of this LoginPage class lies in its build() method. By returning a Scaffold widget enveloping a Column widget, it lays the foundation for a structured login page. But there’s more to it. This Column widget plays host to three crucial children: email input, password input, and a login button – all implemented using TextField and FlatButton widgets.

As users type their email and password, onChanged callbacks from TextField widgets leap into action, updating the _LoginPageState class accordingly. Not to be left behind, the FlatButton widget’s onPressed callback swoops in, managing the login process with finesse.

This login page, while simple, is a stepping stone to crafting more intricate login pages with Flutter. By harnessing other widgets like Container, MediaQuery, and Form, you can tailor the login page’s look and behavior to your heart’s content. So go ahead, explore the world of Flutter, and create a login experience that’s uniquely yours.
