Introduction Every time you interact with the internet—whether it is loading a webpage, making a purchase online, or sending a request to an API—the process involves a request and a response. The server’s response not only contains the requested data but also a status code. These status codes are essential because they immediately tell the…

APIs are at the heart of modern software development, enabling applications to communicate and share data across platforms, devices, and systems. Among the many data exchange formats available, JSON (JavaScript Object Notation) has become the most dominant and widely used. From web applications to mobile apps, cloud services to IoT devices, JSON is the go-to…

JSON, which stands for JavaScript Object Notation, is one of the most popular formats for data exchange on the web. It is lightweight, easy to understand, and human-readable, which makes it a natural choice for APIs. In today’s interconnected digital world, almost every application communicates with others through APIs, and JSON has emerged as the…

When working with web development, APIs, or networking, understanding HTTP methods is one of the most important fundamentals. HTTP (Hypertext Transfer Protocol) defines a set of request methods that specify the action to be performed on a resource. These methods are verbs like GET, POST, PUT, PATCH, and DELETE that clearly describe what the client…

Introduction In the world of web communication, every action on the internet follows a request-response cycle. Whenever you type a URL into your browser or use an app that fetches data from a server, a request is sent from your device to a web server. The server then processes the request and sends back a…

In the world of web communication, HTTP (Hypertext Transfer Protocol) plays a crucial role in how clients and servers exchange information. Almost every website or web-based application you interact with relies on HTTP requests to send and receive data. Whether you open a webpage, submit a form, or interact with an API, you are triggering…

A REST API, short for Representational State Transfer Application Programming Interface, is one of the most widely used architectural styles for designing web services. It provides a set of rules and conventions that allow different software systems to communicate over the internet using the principles of REST. REST APIs make it easier for clients and…

Introduction In the digital era, applications rarely work in isolation. Every mobile app, website, or enterprise system needs to communicate with other software to share data and provide seamless user experiences. This communication is made possible through something called an API, which stands for Application Programming Interface. At its core, an API is a bridge…

Lists and grids are the backbone of many mobile applications. Whether you are building a shopping app, a news feed, or a gallery, these widgets help display large amounts of structured content in a scrollable and interactive format. Flutter provides powerful widgets such as ListView, GridView, and their builder counterparts to make creating lists and…

Modern mobile applications deal with large datasets — news feeds, product listings, chat messages, search results, social media timelines. Loading all of this data at once is inefficient and leads to poor performance. Instead, developers use infinite scrolling and pagination techniques. With infinite scrolling, the app fetches more data when the user scrolls to the…
