Building a Wallet UI in Flutter

Arouna Sidibé — Sat, 07 Oct 2023 16:31:12 +0000

Flutter, developed by Google, is a popular open-source UI software development toolkit that allows developers to create natively compiled applications for mobile, web, and desktop from a single codebase. Its hot-reload feature, expressive UI components, and rich ecosystem make it an excellent choice for creating stunning interfaces.

N.B: the complete source code is available on my github account: https://github.com/ronphobos

Setting Up

You can install the Flutter SDK by clicking this link Download and install Flutter

Create a New Flutter Project by typing in your terminal:
flutter create wallet_ui

Open the Project:
Use your favorite code editor to open the wallet_ui directory.

First of all create the config folders 📁 which will contain the configuration data, colors of our application and widgets 📁 which will contain the widgets of our application.

Then at the root of the project, create the assets folder for the images and the fonts folder for the typo.

Clear the contents of main.dart file in lib folder and paste the following code

import 'package:flutter/material.dart';
import 'package:test1/config/data.dart';
import 'package:test1/widgets/CardSection.dart';
import 'package:test1/widgets/PieChart.dart';
import 'package:test1/widgets/header.dart';

void main() {
  runApp(
    MaterialApp(
      debugShowCheckedModeBanner: false,
      home: MyApp(),
      theme: ThemeData(fontFamily: 'Circular'),
    ),
  );
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: AppColors.primaryWhite,
      body: Column(
        children: [
          SizedBox(
            height: 8,
          ),
          Container(
            height: 120,
            child: WalletHeader(),
          ),
          Expanded(
            child: CardSection(),
          ),
          Expanded(
            child: PieChart(),
          )
        ],
      ),
    );
  }
}

in the config folder, let create a data.dart file and paste the following code

import 'package:flutter/material.dart';

class AppColors {
  static Color primaryWhite = Color(0xFFCADCED);
  static Color orange = Colors.deepOrange;

  static List pieColors = [
    Colors.indigo[400],
    Colors.blue,
    Colors.green,
    Colors.amber,
    Colors.deepOrange,
    Colors.brown,
  ];

  static List<BoxShadow> neumorpShadow = [
    BoxShadow(
        color: Colors.white.withOpacity(0.5),
        spreadRadius: -5,
        offset: Offset(-5, -5),
        blurRadius: 30),
    BoxShadow(
        color: Colors.blue[900]!.withOpacity(.2),
        spreadRadius: 2,
        offset: Offset(7, 7),
        blurRadius: 20)
  ];
}

List category = [
  {"name": "Paiement effectué Djamo", "amount": 500.0},
  {"name": "Netflix", "amount": 100.0},
  {"name": "Google Play fees", "amount": 80.0},
  {"name": "Facture électricité", "amount": 50.0},
  {"name": "Aliexpress fees", "amount": 100.0},
  {"name": "CV en ligne", "amount": 30.0},
];

in the widget folder create a header.dart file and paste this

import 'package:flutter/material.dart';
import 'package:test1/config/data.dart';

class WalletHeader extends StatelessWidget {
  const WalletHeader({super.key});

  @override
  Widget build(BuildContext context) {
    return Container(
      margin: const EdgeInsets.symmetric(horizontal: 20),
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: [
          const Text(
            "Mon portefeuille",
            style: TextStyle(fontSize: 25, fontWeight: FontWeight.bold),
          ),
          Container(
            height: 50,
            width: 50,
            decoration: BoxDecoration(
              shape: BoxShape.circle,
              color: AppColors.primaryWhite,
              boxShadow: AppColors.neumorpShadow,
            ),
            child: Stack(
              children: [
                Center(
                  child: Container(
                    decoration: BoxDecoration(
                      shape: BoxShape.circle,
                      color: AppColors.orange,
                      boxShadow: AppColors.neumorpShadow,
                    ),
                  ),
                ),
                Center(
                  child: Container(
                    margin: const EdgeInsets.all(4),
                    decoration: BoxDecoration(
                      shape: BoxShape.circle,
                      color: AppColors.primaryWhite,
                      boxShadow: AppColors.neumorpShadow,
                    ),
                  ),
                ),
                const Center(
                  child: Icon(Icons.notifications),
                ),
              ],
            ),
          ),
        ],
      ),
    );
  }
}

for the card section, create a cardSection.dart file and paste this

import 'package:flutter/material.dart';
import 'package:test1/config/data.dart';
import 'package:test1/widgets/cardDetail.dart';

class CardSection extends StatelessWidget {
  const CardSection({super.key});

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Text(
          'Carte selectionnée',
          style: TextStyle(fontWeight: FontWeight.bold, fontSize: 20),
        ),
        Expanded(
          child: ListView.builder(
            scrollDirection: Axis.horizontal,
            itemCount: 2,
            itemBuilder: (context, i) {
              return Container(
                width: MediaQuery.of(context).size.width,
                margin: EdgeInsets.symmetric(horizontal: 20, vertical: 40),
                decoration: BoxDecoration(
                  color: AppColors.primaryWhite,
                  boxShadow: AppColors.neumorpShadow,
                  borderRadius: BorderRadius.circular(20),
                ),
                child: Stack(
                  children: [
                    Positioned.fill(
                      left: -300,
                      top: -100,
                      bottom: -100,
                      child: Container(
                        decoration: BoxDecoration(
                            boxShadow: AppColors.neumorpShadow,
                            shape: BoxShape.circle,
                            color: Colors.white30),
                      ),
                    ),
                    CardDetail()
                  ],
                ),
              );
            },
          ),
        )
      ],
    );
  }
}

create a cardDetail.dart file for designing the details of the card

import 'package:flutter/material.dart';
import 'package:test1/config/data.dart';

class CardDetail extends StatelessWidget {
  const CardDetail({super.key});

  @override
  Widget build(BuildContext context) {
    return Stack(
      children: [
        Align(
          alignment: Alignment.topLeft,
          child: Container(
              width: 250, child: Image.asset('assets/mastercardlogo.png')),
        ),
        Align(
          alignment: Alignment.bottomRight,
          child: Padding(
            padding: const EdgeInsets.all(20.0),
            child: Container(
              width: 70,
              height: 50,
              decoration: BoxDecoration(
                  color: AppColors.primaryWhite,
                  boxShadow: AppColors.neumorpShadow,
                  borderRadius: BorderRadius.circular(15)),
            ),
          ),
        ),
        Align(
          alignment: Alignment.bottomLeft,
          child: Container(
            child: Padding(
              padding: const EdgeInsets.only(bottom: 20, left: 10),
              child: Column(
                mainAxisAlignment: MainAxisAlignment.end,
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  Row(
                    children: [
                      Text(
                        "**** **** **** ",
                        style: TextStyle(
                            fontSize: 20, fontWeight: FontWeight.bold),
                      ),
                      Text(
                        "5850",
                        style: TextStyle(
                            fontSize: 30, fontWeight: FontWeight.bold),
                      ),
                    ],
                  ),
                  Text(
                    "Carte Platine",
                    style: TextStyle(fontSize: 16, fontWeight: FontWeight.bold),
                  )
                ],
              ),
            ),
          ),
        )
      ],
    );
  }
}

and the for the last section, you will need to create the PieChart.dart file

import 'package:flutter/material.dart';
import 'package:test1/config/data.dart';

class PieChart extends StatelessWidget {
  const PieChart({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Text(
          "Dépenses",
          style: TextStyle(fontWeight: FontWeight.bold),
        ),
        Row(
          children: [
            Expanded(
              flex: 5,
              child: Container(
                margin: EdgeInsets.symmetric(horizontal: 20, vertical: 40),
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                  children: category
                      .map(
                        (value) => Padding(
                          padding: const EdgeInsets.all(4.0),
                          child: Row(
                            children: [
                              CircleAvatar(
                                radius: 5,
                                backgroundColor: AppColors
                                    .pieColors[category.indexOf(value)],
                              ),
                              SizedBox(
                                width: 5,
                              ),
                              Row(
                                children: [
                                  Text(
                                    value['name'],
                                    style: TextStyle(fontSize: 18),
                                  ),
                                  Text(
                                    ':',
                                    style: TextStyle(fontSize: 18),
                                  ),
                                  SizedBox(
                                    width: 10,
                                  ),
                                  Text(
                                    value['amount'].toString() + 'F',
                                    style: TextStyle(fontSize: 18),
                                  ),
                                ],
                              )
                            ],
                          ),
                        ),
                      )
                      .toList(),
                ),
              ),
            ),
          ],
        ),
      ],
    );
  }
}

Finally, all you have to do is make the fonts and assets folder accessible in this pubspec.yaml file.

in the assets section:


  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/
  #   - images/a_dot_ham.jpeg

  fonts:
    - family: Circular
      fonts:
        - asset: fonts/CircularStd-Medium.ttf
        - asset: fonts/CircularAir-Light.ttf
          weight: 100
        - asset: fonts/CircularStd-Bold.ttf
          weight: 500

Demystifying Unit Tests in Laravel: Building Robust Applications with Confidence

Arouna Sidibé — Mon, 21 Aug 2023 08:53:25 +0000

Introduction

In the ever-evolving world of web development, ensuring the stability and reliability of your applications is paramount. Unit testing is a key practice that empowers developers to catch bugs early, maintain code quality, and confidently deliver high-quality software. In this blog, we'll dive into the world of unit tests in Laravel, one of the most popular PHP frameworks. We'll explore what unit tests are, why they are crucial, and how you can effectively implement them to build robust applications with confidence.

Understanding Unit Tests

Unit testing is a software testing methodology in which individual components or units of a software application are tested in isolation. In Laravel, a unit test focuses on testing a single method or function within a class, ensuring that it behaves as expected and meets the specified requirements. By isolating the unit being tested, developers can pinpoint errors, validate functionality, and validate edge cases, all of which contribute to overall code reliability.

Why Unit Tests Matter

Early Detection of Bugs 🔎: Writing unit tests allows you to identify bugs and issues in your codebase at an early stage. Catching these issues before they reach production saves time, effort, and resources in the long run.
Code Quality: Unit tests promote good coding practices by encouraging modular and well-structured code. When you design your code with testability in mind, it often leads to more maintainable and extensible software.
Refactoring Confidence: Refactoring, or making changes to your codebase, becomes less risky with a comprehensive suite of unit tests. You can confidently make changes knowing that the tests will alert you to any regressions.
Documentation 📜: Unit tests serve as living documentation for your code. They provide clear examples of how specific components should be used and behave, which can be especially valuable for other developers working on the project.

Creating Unit Tests in Laravel

Laravel provides a robust testing framework that makes writing unit tests a breeze. Here's a step-by-step guide to creating unit tests in Laravel:

Ensure you have a Laravel project up and running. You can use Composer to create a new Laravel project:

composer create-project --prefer-dist laravel/laravel Yondaine
Replace "Yondaine" with your desired project name.

Set Up Testing Environment: Laravel includes PHPUnit, a popular testing library for PHP. Ensure you have PHPUnit installed by default with Laravel.

Generate a Test Class: Laravel's artisan command-line tool allows you to generate test classes effortlessly. Run php artisan make:test MyTest to create a new test class named MyTest.

This will create a new test file named MyTest.php in the tests/Unit directory.

Write Test Methods: In the generated test class, you can define test methods that correspond to the methods you want to test. Each test method should start with the word testand use assertion methods provided by PHPUnit to validate the expected behavior of your code. Open the newly created test file (e.g., tests/Unit/MyTest.php) and start writing your test logic. For example:

use Tests\TestCase;

class MyTest extends TestCase
{
    public function isFour()
    {
        $result = 2 + 2;
        $this->assertEquals(4, $result);
    }
}

In this example, we're testing basic addition.

Run Tests: Use the php artisan test command to run all the tests in your project. Laravel's testing framework will automatically discover and execute your test classes. To run only tests with a specific group, you can use:

php artisan test --group=users

Best Practices for Effective Unit Testing

Isolate Dependencies: When writing unit tests, ensure that you isolate the unit being tested from external dependencies. You can use techniques like mocking and dependency injection to achieve this isolation.
Test Cases: Create test cases that cover different scenarios, including edge cases and possible error scenarios. This ensures thorough coverage and helps you catch potential issues.
Use Meaningful Names: Give your test methods and classes descriptive names that clearly convey their purpose. This makes it easier for you and other developers to understand the tests' intentions.
Keep Tests Fast: Unit tests should be fast to execute. Slow tests can hinder the development process, so avoid unnecessary database interactions or network calls within your unit tests.

Conclusion

Unit tests are a crucial tool in a developer's arsenal for building reliable and maintainable applications. In Laravel, the testing framework simplifies the process of writing and executing unit tests, allowing you to catch bugs early, ensure code quality, and refactor confidently. By incorporating unit tests into your development workflow, you can create robust applications that stand the test of time and deliver exceptional value to your users.

Safeguarding Your Digital World: The Imperative of Data Security

Arouna Sidibé — Thu, 17 Aug 2023 15:20:11 +0000

In today's hyper-connected digital age, data has become one of the most valuable commodities. From personal information to sensitive business data, our lives are intricately woven into the digital fabric. With this growing dependency on data, the need for robust data security has never been more critical. In this blog post, we'll explore the importance of data security, its challenges, and practical steps you can take to safeguard your digital world.

The Importance of Data Security

Data security refers to the practice of protecting digital data from unauthorized access, corruption, or theft. It encompasses a range of strategies and measures aimed at ensuring the confidentiality, integrity, and availability of data. Here's why data security matters:

Protection of Personal Privacy: In an era where personal information is frequently shared online, safeguarding sensitive details such as financial data, medical records, and personal communications is paramount. Data breaches can lead to identity theft, financial loss, and emotional distress.
Preservation of Business Confidentiality: For businesses, data is often a competitive advantage. From proprietary algorithms to customer databases, unauthorized access can lead to intellectual property theft, financial fraud, and damage to reputation.
Compliance and Legal Requirements: Numerous laws and regulations, such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA), mandate the protection of certain types of data. Non-compliance can result in hefty fines and legal consequences.
Trust and Reputation: Individuals and organizations that prioritize data security build trust with their customers, partners, and stakeholders. A breach can erode trust and tarnish the reputation built over years.

Challenges in Data Security

While the need for data security is evident, numerous challenges complicate its implementation:

Evolving Threat Landscape: Cyberattacks are becoming increasingly sophisticated and diverse. From ransomware attacks to phishing scams, hackers constantly adapt their tactics to exploit vulnerabilities.
Human Factor: Often, data breaches occur due to human errors or negligence, such as weak passwords, unsecured devices, or accidental data exposure.
Data Proliferation: The proliferation of data across devices, cloud services, and platforms makes it challenging to track and secure every piece of information effectively.
Balancing Security and Accessibility: Striking the right balance between data security and accessibility is a constant struggle. Overly strict security measures can hinder productivity, while lax measures can compromise data integrity.

Practical Steps to Enhance Data Security

Use Strong Authentication: Implement multi-factor authentication (MFA) wherever possible. MFA adds an extra layer of security by requiring users to provide two or more forms of verification before accessing data.
Regular Software Updates: Keep operating systems, applications, and security software up to date. Updates often include patches for known vulnerabilities.
Data Encryption: Encrypt sensitive data both in transit and at rest. Encryption converts data into a code that can only be deciphered with the appropriate decryption key.
Employee Training: Educate employees about data security best practices. Training can reduce the risk of human errors that often lead to data breaches.
Network Security: Utilize firewalls, intrusion detection systems, and secure network protocols to protect data from unauthorized access.
