How to Create a Flutter Login Screen with Animation Effects

Oct 29, 2023 | Programming

In this guide, we’ll walk you through the process of creating a beautiful, animated login/signup screen using Flutter. The key component we’ll be using is the FlutterLogin widget, which comes packed with animation effects to elevate user experience.

Installation

To get started, first install the FlutterLogin package by following the installation instructions here.

Setting Up the Login Screen

Once you’ve installed the package, you can create a login screen. Think of creating your login screen as setting up a welcoming gate to a theme park. It needs to be inviting, functional, and effectively handle guest entries!

Basic Code Structure

Here’s a skeletal structure of a basic login screen utilizing the FlutterLogin widget:

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

const users = {
  'dribbble@gmail.com': '12345',
  'hunter@gmail.com': 'hunter',
};

class LoginScreen extends StatelessWidget {
  const LoginScreen(super.key);

  Duration get loginTime => const Duration(milliseconds: 2250);

  Future _authUser(LoginData data) {
    return Future.delayed(loginTime).then((_) {
      if (!users.containsKey(data.name)) {
        return 'User not exists';
      }
      if (users[data.name] != data.password) {
        return 'Password does not match';
      }
      return null;
    });
  }

  @override
  Widget build(BuildContext context) {
    return FlutterLogin(
      title: 'ECORP',
      logo: const AssetImage('assets/images/ecorp-lightblue.png'),
      onLogin: _authUser,
    );
  }
}

In the code above, _authUser functions like a gatekeeper, validating the user’s credentials before letting them through to the next part of the application, much like a thrilled attendant at the entrance of a theme park checking tickets.

Customizing Your Login Widget

Your login screen can be customized to reflect your brand identity. You have various properties to tweak, such as:

  • title: The name of your app displayed prominently.
  • logo: An eye-catching logo that adds appeal.
  • messages: Custom messages for button texts, hints, etc.

For example, you can change the background color to a more visually appealing tone to show off your unique style.

Troubleshooting

Things may not always go smoothly. If you encounter issues, here are some troubleshooting tips:

  • Ensure your packages are properly installed and imported.
  • Check your validation logic in the authentication methods.
  • Be mindful of the asset paths you provide for images and logos.
