Top Libraries For Making HTTP Requests in Flutter

Best Libraries For Making HTTP Requests in Flutter

In this article, we will be taking a look at the best HTTP Request Packages available to us in Flutter for working with HTTP requests.

POST, GET, and other HTTP queries are commonly required by applications.

Flutter has a many packages that allows developers to make HTTP queries.

In this post we will discuss the top open-source libraries for making HTTP requests in Flutter apps. Without further ado, let’s get into the meat of the subject.

Http

This package is presently the most popular HTTP package on pub.dev, as published by the Dart team. It provides a high-level API that can make dealing with network activities a lot easier. You may use the following command to install it:

flutter pub add http

Sample code:

import 'package:http/http.dart' as http; void sendPostRequest() async { final url = Uri.parse('https://test.kindacode.com/api/v3/'); final response = await http.post(url, body: {'email': 'example@kindacode.com', 'name': 'Mr Happy'}); print('Response status: ${response.statusCode}'); print('Response body: ${response.body}'); }
Code language: JavaScript (javascript)

Requests can be retried using the plugin. To retry unsuccessful requests, use the RetryClient class:

import 'package:http/http.dart' as http; import 'package:http/retry.dart'; Future<void> bootstrap() async { final client = RetryClient(http.Client()); try { print(await client.read(Uri.parse('http://test.kindacode.com/api/v3/'))); } finally { client.close(); } }
Code language: JavaScript (javascript)

Dio: HTTP Requests Module Flutter

Dio is the Flutter ecosystem’s fastest-growing HTTP package. It’s quite strong and easy to use. The package includes a number of incredibly helpful features, including:

  • Global configuration
  • Interceptors
  • FormData
  • Request Cancellation
  • Retrying Requests
  • File Downloading
  • Timeout
  • Https certificate verification
  • Http2

You can install Dio by using the following command:

flutter pub add dio

Sample code for using Dio:

import 'package:dio/dio.dart'; void getData() async { try { var response = await Dio().get('http://www.example.com'); print(response); } catch (e) { print(e); } }
Code language: JavaScript (javascript)

Dio has several extensions:

Retrofit: HTTP Requests Module Flutter

Retrofit is a dio client generator that converts types. It’s similar to TypeScript’s decorators in that it allows you to create code using @Something. Consider the following code:

@JsonSerializable() class MyClass {} @PATCH("your-api-endpoint") Future<Task> updateTaskPart( @Path() String id, @Body() Map<String, dynamic> map); @PUT("your-api-endpoint") Future<Task> updateTask(@Path() String id, @Body() Task task); @DELETE("your-api-endpoint") Future<void> deleteTask(@Path() String id); @POST("your-api-endpoint") Future<Task> createTask(@Body() Task task);
Code language: JavaScript (javascript)

For more details, please see retrofit’s docs.

Chopper: HTTP Requests Module Flutter

Chopper is another HTTP client generator for Dart and Flutter, similar to Retrofit. Chopper, chopper generator, and build runner must all be installed. Please visit Chopper’s official documentation for further information on how to use it.
