A composable, Future-based library for making HTTP requests.

This package contains a set of high-level functions and classes that make it easy to consume HTTP resources. It's multi-platform (mobile, desktop, and browser) and supports multiple implementations.

Using

The easiest way to use this library is via the top-level functions. They allow you to make individual HTTP requests with minimal hassle:

import 'package:http_platforms/http_platforms.dart' as http;

var url = Uri.https('example.com', 'whatsit/create');
var response = await http.post(url, body: {'name': 'doodle', 'color': 'blue'});
print('Response status: ${response.statusCode}');
print('Response body: ${response.body}');

print(await http.read(Uri.https('example.com', 'foobar.txt')));

Choosing an implementation

There are multiple implementations of the package:http client interface. By default, package:http uses browserclient on the web and ioclient on all other platforms. You can choose a different client implementation based on the needs of your application.

You can change implementations without changing your application code, except for a few lines of configuration.

Some well-supported implementations are:

Configuration

To use an HTTP client implementation other than the default, you must:

1. Add the HTTP client as a dependency.
2. Configure the HTTP client.
3. Connect the HTTP client to the code that uses it.

1. Add the HTTP client as a dependency.

To add a package compatible with the Dart SDK to your project, use dart pub add.

For example:

# Replace  "fetch_client" with the package that you want to use.
dart pub add fetch_client

To add a package that requires the Flutter SDK, use flutter pub add.

Supporting browser and native

If your application can be run in the browser and natively, you must put your browser and native configurations in separate files and import the correct file based on the platform.
