Implement GraphQL with HTTP in Flutter

GraphQL has gained immense popularity in modern app development due to its flexibility in fetching only the required data.

When combined with Flutter, a leading framework for cross-platform development, it can elevate the efficiency and performance of your app.

In this blog, we’ll explore how to Implement GraphQL with HTTP in Flutter for seamless data querying.

What is GraphQL?

GraphQL is an open-source query language developed by Facebook.

Unlike REST APIs, GraphQL provides a more dynamic and efficient approach to interacting with APIs by allowing clients to request only the specific data they need.

This reduces over-fetching or under-fetching of data, making applications more efficient.

Implementation

To begin with GraphQL in Flutter, you need to set up your Flutter project.

Add dependencies: To use HTTP for GraphQL, you’ll need the http package. Add the following to your pubspec.yaml file:

Run flutter pub get to fetch the dependencies.

Understanding GraphQL Basics

GraphQL operates on two main operations:

Each operation is structured as a JSON-like query but uses a specific syntax to define what data is needed.

Error Handling

GraphQL responses often include a errors field. To handle errors:
