  Flutter Provider: FutureProvider vs ChangeNotifierProvider vs StreamProvider for API Calls State management is crucial in Flutter apps, especially when handling API calls. In this post, we will explore   FutureProvider   for automatic API fetching,   ChangeNotifierProvider   for manual control, and   StreamProvider   for real-time data updates. 1. Using FutureProvider for Automatic API Calls FutureProvider is useful when you want to   fetch data once and automatically update the UI   when the data is received. Example: Fetching Posts from an API Using FutureProvider import 'dart:convert' ; import 'package:flutter/material.dart' ; import 'package:provider/provider.dart' ; import 'package:http/http.dart' as http; void main () { runApp( FutureProvider <List< dynamic >>( create: (context) => fetchPosts(), initialData: [], child: MyApp (), ), ); } Future<List< dynamic >> fetchPosts () asyn...

  Why Use Provider for API Calls? When building Flutter apps, managing API calls efficiently is crucial.   Provider   simplifies this by handling state management and ensuring smooth UI updates. In this blog, we'll learn how to use   Provider   for API calls, fetching data from a remote server and displaying it in a Flutter app. Let's dive in!   Setting Up Dependencies First, add the required packages to your project: flutter pub add provider http provider : Manages state efficiently. http : Helps in making network requests. Creating API Service Class This class will handle the API requests. import 'dart:convert' ; import 'package:http/http.dart' as http; class ApiService { Future<List< dynamic >> fetchPosts () async { final response = await http.get(Uri. parse ( 'https://jsonplaceholder.typicode.com/posts' )); if (response.statusCode == 200 ) { return jsonDecode(response.body); } else { throw Exception ( "Faile...

  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. If you haven’t already, you’ll need to add the Hive package and the Hive Flutter package to your pubspec.yaml : # versions available, run `flutter pub outdated`. dependencies : flutter : sdk : flutter # The follow...
