  How to Use Hive for Storing and Retrieving Data in Flutter with Custom Models Introduction In mobile app development, especially with Flutter, local storage plays a crucial role in persisting data. One of the most popular solutions for local data storage in Flutter is Hive , a lightweight and fast NoSQL database that provides a simple API for storing and retrieving data. In this blog, we’ll walk through how to use Hive with custom models in Flutter. We’ll demonstrate how to store and retrieve data of a custom model ( User ), using Hive's built-in functionality. We will also discuss the importance of null safety when dealing with data retrieval. Setting Up Hive in Flutter Before diving into the code, let’s first ensure that Hive is set up in your Flutter project.

Mastering FutureBuilder in Flutter: A Simple Guide for Beginners

Flutter provides many powerful tools to make app development easier, and one such tool is the **FutureBuilder** widget. If you’re working with asynchronous data, such as loading data from a database or performing any background operation, `FutureBuilder` is an excellent way to handle the state and update the UI accordingly. Let’s explore **FutureBuilder** and how to use it. ### **What is FutureBuilder?** In Flutter, a ` FutureBuilder ` is a widget that allows you to handle asynchronous data. It listens to a `Future` and rebuilds the widget based on the result of that `Future`. When you call an asynchronous operation, like a network request or a database query, `FutureBuilder` allows you to display different UI states based on the task's status, such as loading, error, or success. ### **How Does FutureBuilder Work?** The ` FutureBuilder ` widget takes two main parameters: 1. **`future`**: This is the `Future` that you want to run. It could be an API call, database query, or any othe...

Packages and Plugins in Flutter Explained Simply

Image
  In Flutter, packages and plugins are essential tools that help developers add features to their apps. They are pre-built code collections that can be easily integrated into an app to perform specific tasks. While both serve a similar purpose, there is a small difference between them. 1. Packages: In Flutter, packages are reusable libraries of Dart code that add specific features to your project.   These packages are available on pub.dev , the official Flutter package repository.   Developers can easily search for packages and add them to their projects by listing them in the pubspec.yaml file, which is used to manage project dependencies.   Examples of common packages include ones for making HTTP requests (like http) or for state management (like provider). 2.  Plugins: Plugins are a special type of package designed to work with platform-specific features or native services.   They enable Flutter apps to interact with device features like the camera...
