## What it is
package:http is the official Dart/Flutter library providing a composable, Future-based API for making HTTP requests across mobile, desktop, web, and wasm platforms. It includes a Client abstraction with swappable implementations (IOClient, BrowserClient, Cronet, OkHttp, Cupertino) plus wrappers like RetryClient and MockClient.

## Use cases
- make http requests in dart
- fetch data from an api in flutter
- call a rest api from a dart app
- retry failed http requests automatically
- mock http responses in dart tests
- use websockets in dart
- make http requests that work on web and mobile

## When to choose
- you're building a Dart or Flutter app that consumes HTTP APIs
- you need one client API that works across mobile, desktop, web, and wasm
- you want composable client wrappers for retries, logging, or mocking
- you want platform-native HTTP stacks like Cronet, OkHttp, or NSURLSession

## When to avoid
- you need a low-level socket or raw TCP client rather than HTTP
- you're not working in Dart or Flutter
- you need server-side features like routing or middleware for serving requests (use shelf instead)
- you need advanced gRPC or non-HTTP protocols

## Facets
- artifact type: library
- maturity: stable
- function: http-client, websocket, middleware
- domain: web-development, developer-tools, apis, cross-platform
- platform: cross-platform, windows, browser, wasm
