Implementation

@override
Future<Iterable<Response>> send(
    Iterable<PhoneNumber> to, Message message, http.Client client) async {
  final requests = await groupRequests(to, message);
  final responses = requests.map<Future<Iterable<Response>>>((e) async {
    final streamedResponse = await client.send(e.key);
    final httpResponse = await http.Response.fromStream(streamedResponse);

    return e.value.map(
      (to) => Response(
        gateway: this,
        to: to,
        success: httpResponse.body == '0',
        response: httpResponse,
      ),
    );
  });

  final results = await Future.wait(responses);

  return results.expand((e) => e);
