In the process of mobile app development, state management is a crucial aspect. Properly managing the application state is vital to provide an efficient user experience. Flutter offers several options for state management, and one of them is the Riverpod package. Riverpod is a powerful and flexible state management solution that can be easily used in Flutter applications. In this article, we will explore the core concepts of the Riverpod package and demonstrate how to use it through a sample application.

  1. What is Riverpod? Riverpod is an enhanced version of the Provider package designed for Flutter. It aims to simplify state management and create a more organized code structure. Riverpod provides a robust dependency injection and update mechanism, enabling effective management of application state.
  2. Key Concepts of Riverpod a. Provider: At the heart of the Riverpod package is the Provider, which is an object that supplies application state. It can listen for changes and provide the current state. For example, you can use a Provider to manage a user's authentication status.

b. Consumer: The Consumer receives the state from the Provider and ensures its visibility in the user interface. By using the Consumer while creating a widget, you can track the state and automatically detect updates.

c. Family: The Family allows you to create multiple instances of a Provider. It is often used to manage list-based states. For example, you can create a separate Provider for each item in a list when performing operations on it.

  1. Creating a Sample Application with Riverpod Let's understand Riverpod better by building a simple task list application. The application will allow the user to add and complete tasks.

Step 1: Project Setup Install the Flutter SDK and create a new Flutter project.

Step 2: Add the Riverpod Package Add the "riverpod" package to the dependencies section in your pubspec.yaml file and update the project dependencies.

Step 3: Create the Task Data Model

class Task {
final String title;
final bool isCompleted;

Task(this.title, {this.isCompleted = false});

Step 4: Create the Provider

final taskProvider = Provider<List<Task>>((ref) => []);

Step 5: Write Functions for Adding and Toggling Tasks

void addTask(ProviderRef<List<Task>> ref, String title) {
final taskList =;
final newTask = Task(title);

void toggleTask(ProviderRef<List<Task>> ref, int index) {
final taskList =;
final task = taskList[index];
final updatedTask = Task(task.title, isCompleted: !task.isCompleted);
taskList[index] = updatedTask;

Step 6: Create the User Interface

class TaskListScreen extends StatelessWidget {
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Task List'),
body: Consumer(
builder: (context, watch, _) {
final tasks = watch(taskProvider);
return ListView.builder(
itemCount: tasks.length,
itemBuilder: (context, index) {
final task = tasks[index];
return ListTile(
title: Text(task.title),
trailing: Checkbox(
value: task.isCompleted,
onChanged: (_) => toggleTask(, index),
floatingActionButton: FloatingActionButton(
onPressed: () {
final taskTitle = 'New Task'; // We are using a fixed task title for demonstration purposes
addTask(, taskTitle);
child: Icon(Icons.add),

In this article, we explored the Riverpod package in Flutter and demonstrated its usage through a sample task list application. Riverpod is a powerful package that simplifies state management in Flutter and promotes a more organized code structure. By using Riverpod, you can effectively manage application state and provide an enhanced user experience.

Remember, the concepts discussed in this article provide a foundation for understanding Riverpod, but the package offers more advanced features. For further information, refer to the official Riverpod documentation.
