Introduction Flutter is a modern framework for building cross-platform applications with a single codebase. It uses a reactive and declarative approach where the user interface is built using widgets. Every visual component in Flutter is a widget, and widgets are the building blocks of the entire framework. There are two major types of widgets in…

When learning Flutter, one of the first concepts you encounter is the widget. Everything in Flutter is a widget: text, buttons, images, containers, and even the entire app itself. Widgets come in two main types: This article focuses on Stateless Widgets. We’ll explore what they are, how they work, when to use them, and why…

When you start developing with Flutter, the first concept you will hear again and again is “everything in Flutter is a widget.”This simple phrase forms the foundation of Flutter’s architecture and UI design system. From a basic Text label to a complex animated screen, everything you see on the screen in a Flutter app is…

Introduction When you start learning Flutter, the very first file you encounter is main.dart. This file is the entry point of every Flutter application. It contains the main() function and the root runApp() call that launches your app. For beginners, it is tempting to put all of your application logic, UI code, and widgets inside…

One of the most important skills for any Flutter developer is not just writing code but organizing it properly. When you first create a Flutter project, the lib/ folder looks simple. It usually contains only one file: main.dart. At the beginning, this is fine. But as your app grows in size and complexity, your lib/…

When working with any software project, especially one that uses Git for version control, you will come across a file named .gitignore. This small but powerful file plays a huge role in maintaining a clean and efficient Git repository. In Flutter (and Dart projects), .gitignore is especially important because certain files and folders — such…

Introduction When you create a project in modern development environments such as IntelliJ IDEA, Android Studio, or Visual Studio Code (VS Code), you will often notice the presence of hidden folders like .idea/ or .vscode/. These folders are automatically generated by the Integrated Development Environment (IDE) and contain configuration files that store project-specific settings. Although…

When you open a Flutter project in your editor for the first time, you’ll notice several folders like lib/, android/, ios/, web/, and build/. While folders such as lib/ contain your actual app code, the build/ folder is different. It’s not a folder you directly write code in, but it plays an essential role in…

When working with Flutter and Dart, you’ll notice several folders inside your project directory — lib/, android/, ios/, test/, and others. Among them, there is a special hidden folder named .dart_tool/. At first glance, many developers wonder: What is this folder? Why is it hidden? Can I delete it? Should I edit its files? The…

The file pubspec.yaml is a YAML (YAML Ain’t Markup Language) configuration file that Flutter uses to understand the setup of your app. It includes: But among all these, the Dependencies section is the most frequently updated because almost every app relies on third-party libraries. What Are Dependencies? In programming, a dependency is any external piece…
