One of the greatest strengths of Flutter is its flexibility in handling assets — the external files that your app needs, such as images, JSON data, animations, audio, or other resources. Assets give life to your app: they define how it looks, what content it shows, and how users interact with it. In Flutter, assets…

Introduction When you create a Flutter project, one of the most important configuration files you will work with is pubspec.yaml. This file defines your project’s metadata, its assets, and most importantly, its dependencies. Dependencies are external libraries or tools that extend the functionality of your app. In Flutter and Dart, dependencies are divided into two…

When you open any Flutter project, one of the first files you’ll notice at the root level is pubspec.yaml. At first glance, it may look like just another configuration file filled with indentation and strange syntax. But in reality, pubspec.yaml is the heart of every Flutter project. If the lib/ folder is where your Dart…

When you start building apps with Flutter, one of the folders you’ll see inside your project is the test/ folder. At first, many beginners ignore it, thinking it’s unnecessary or too advanced. But as your project grows, you’ll realize that testing is the backbone of reliable and scalable app development. The test/ folder is where…

When you create a new Flutter project, you immediately see a number of folders: android, ios, lib, test, web, and some configuration files. Each of these has a specific purpose. Among them, the ios folder is crucial for building and running your Flutter app on Apple devices like iPhones and iPads. The ios folder contains…

When you create a new Flutter project, you get several folders like lib/, ios/, test/, and android/. Among these, the android folder plays a very special role.

Flutter has become one of the most popular frameworks for developing mobile, web, and desktop applications because of its speed, flexibility, and ability to create beautiful user interfaces with a single codebase. Every Flutter project, whether simple or complex, begins with a single file called main.dart. This file is not just a piece of boilerplate…

When you first create a new Flutter project, you see multiple folders like android, ios, web, test, and most importantly, lib.

For many beginners, this structure looks complicated because there are so many files and folders that you may have never seen before. However, once you understand the purpose…

Dart, the programming language powering Flutter, is an object-oriented language. Object-oriented programming (OOP) is a programming paradigm that revolves around objects and classes, allowing developers to model real-world entities efficiently. Understanding classes and objects is fundamental to writing clean, maintainable, and scalable Dart code. This article explores classes, objects, and how to create your first…
