patch function

JetLeaf's Routing DSL provides a concise, functional way to create and register HTTP routes without explicitly instantiating Route or calling RouterBuilder.route manually.

Each function corresponds to a standard HTTP method (e.g. get, post) and produces a preconfigured RouterBuilder containing a single route.

You can then:

• Chain additional routes with the builder API, or
• Compose routes together using .and(), .group(), etc.

Example

import 'package:jetleaf/jetleaf.dart';

final router = get('/hello', (req) => 'Hello, JetLeaf!')
  .and(post('/save', (req) => {'status': 'ok'}))
  .and(getX('/ping', (req, res) async {
    await res.getBody().writeString('pong');
  }));

final spec = router.build();

for (final route in spec.routes) {
  print('${route.method} ${route.path}');
}

Design

• Functions ending with X expect a handler signature of (ServerHttpRequest, ServerHttpResponse)
• Non-X variants expect (ServerHttpRequest)
• Each returns a RouterBuilder containing one route definition.
