cronet_http library

An Android Flutter plugin that provides access to the Cronet HTTP client.

import 'package:cronet_http/cronet_http.dart';

void main() async {
  var client = CronetClient.defaultCronetEngine();
  final response = await client.get(
      Uri.https('www.googleapis.com', '/books/v1/volumes', {'q': '{http}'}));
  if (response.statusCode != 200) {
    throw HttpException('bad response: ${response.statusCode}');
  }

  final decodedResponse =
      jsonDecode(utf8.decode(response.bodyBytes)) as Map;

  final itemCount = decodedResponse['totalItems'];
  print('Number of books about http: $itemCount.');
  for (var i = 0; i < min(itemCount, 10); ++i) {
    print(decodedResponse['items'][i]['volumeInfo']['title']);
  }
}

CronetClient is an implementation of the package:http Client, which means that it can easily used conditionally based on the current platform.

void main() {
  var clientFactory = Client.new; // Constructs the default client.
  if (Platform.isAndroid) {
    Future<CronetEngine>? engine;
    clientFactory = () {
      engine ??= CronetEngine.build(
          cacheMode: CacheMode.memory, userAgent: 'MyAgent');
      return CronetClient.fromCronetEngineFuture(engine!);
    };
  }
  runWithClient(() => runApp(const MyFlutterApp()), clientFactory);
}

After the above setup, calling Client methods or any of the package:http convenient functions (e.g. get) will result in CronetClient being used on Android.
