This library provides an http/2 interface on top of a bidirectional stream of bytes.
Here is a minimal example of connecting to a http/2 capable server, requesting a resource and iterating over the response.
import 'dart:convert';
import 'dart:io';
import 'package:http2/http2.dart';
Future<void> main() async {
final uri = Uri.parse('https://www.google.com/');
final transport = ClientTransportConnection.viaSocket(
await SecureSocket.connect(
uri.host,
uri.port,
supportedProtocols: ['h2'],
),
);
final stream = transport.makeRequest(
[
Header.ascii(':method', 'GET'),
Header.ascii(':path', uri.path),
Header.ascii(':scheme', uri.scheme),
Header.ascii(':authority', uri.host),
],
endStream: true,
);
await for (var message in stream.incomingMessages) {
if (message is HeadersStreamMessage) {
for (var header in message.headers) {
final name = utf8.decode(header.name);
final value = utf8.decode(header.value);
print('Header: $name: $value');
}
} else if (message is DataStreamMessage) {
// Use [message.bytes] (but respect 'content-encoding' header)
}
}
await transport.finish();
}An example with better error handling is available here.
