Http3Response class

An HTTP/3 response with status code, headers, and optional body.

Represents a single HTTP/3 response message as defined in RFC 9114. The :status pseudo-header is extracted during decoding and exposed as the integer statusCode. Regular headers are stored in headers with lower-cased keys. An optional binary body may be attached for responses that carry payload.

Http3Response objects are typically obtained via Http3Connection.getResponse after the peer has sent HEADERS and DATA frames on a request stream.

Example

final response = Http3Response(
  statusCode: 200,
  headers: {
    'content-type': 'text/html',
    'cache-control': 'no-cache',
  },
  body: Uint8List.fromList(utf8.encode('<h1>Hello</h1>')),
);
final encoded = response.encodeHeaders();

• Http3Connection.getResponse — retrieves a response for a given stream.
• Http3Request — the corresponding request type.
• RFC 9114 Section 4.1 — HTTP/3 Response Stream.
