browser library

The HTTP and WebSocket clients for code that runs in a browser (Flutter web, Dart compiled to JavaScript or WebAssembly): FetchHttpTransport on the browser's fetch, and BrowserWebSocketTransport on its WebSocket.

Most applications never import this library. platformHttpTransport() and platformWebSocketTransport() from package:spring_web_dart/spring_web_dart.dart already pick these transports on the web, and the Feign and WebSocket starters call those functions. Import it when you want to create a browser transport yourself, for example to declare it as a bean.

import 'package:spring_web_dart/browser.dart';

// The web build of a Flutter app talks to its own origin.
final transport = FetchHttpTransport();

Spring (Java): no equivalent, since Java does not run in a browser.
