Introduction In modern mobile app development, data storage is a crucial part of building reliable and responsive applications. Flutter developers often need a storage solution that is fast, lightweight, easy to use, and capable of working offline. While SharedPreferences works well for small amounts of simple data, many applications require more complex data structures and…

Introduction to SQLite in Flutter SQLite is a powerful, lightweight relational database that is embedded directly into mobile devices. Unlike cloud databases that require an internet connection, SQLite operates entirely on the device, allowing applications to store structured data locally. For Flutter developers, SQLite provides a reliable, performant way to manage relational data with multiple…

When building mobile applications, one of the most common requirements is to store data locally on the device. While cloud databases and APIs provide flexibility for remote storage, many applications also need to manage data offline. This is where SQLite comes in. SQLite is a lightweight relational database engine that is embedded directly into mobile…

In Android development, storing data persistently is one of the most important considerations for creating functional and user-friendly applications. Applications often need to remember user preferences, settings, or small amounts of state information across sessions. One of the most commonly used solutions for this is SharedPreferences. SharedPreferences is a lightweight mechanism that allows developers to…

Introduction When building mobile applications, developers often need a way to store small amounts of data that should persist even when the user closes or restarts the app. For example, you may want to save whether the user is logged in, the selected theme (dark or light mode), or certain user settings like language preference.…

Understanding Local Storage in Mobile Apps Local storage refers to the ability of a mobile application to save and retrieve data directly from the device on which it is running. Unlike cloud storage or remote databases, which rely on an internet connection, local storage provides immediate access to data offline. This makes it a critical…

Introduction to Postman When it comes to working with APIs, developers need tools that can make sending requests and inspecting responses simple and efficient. One such tool that has become an essential part of every developer’s toolkit is Postman. Postman is a collaborative platform that allows developers to design, test, document, and monitor APIs. Whether…

APIs have become an essential part of modern programming, enabling communication between different applications and services. One of the most common operations when working with APIs is retrieving data using an HTTP GET request. In Python, the process of sending and handling GET requests is made extremely simple with the help of the requests library.…

In the world of modern software, APIs are the bridges that allow applications to communicate with each other. These APIs often handle sensitive information such as user details, payment data, or personal messages. Because of this, authentication becomes one of the most critical aspects of API design. API authentication is the process of verifying the…

When it comes to learning about REST APIs, nothing explains the concept better than a clear and practical example. REST (Representational State Transfer) APIs rely on standard HTTP methods like GET, POST, PUT, PATCH, and DELETE to perform actions on resources. Among these, the GET request is the most commonly used method because it is…
