Implementation

Stream<List<int>> getStream({
  required Uri url,
  Map<String, String>? headers,
}) async* {
  final request = http.Request('GET', url);
  if (headers != null) {
    request.headers.addAll(headers);
  }

  final streamedResponse = await _client.send(request);

  if (!_isSuccessStatus(streamedResponse.statusCode)) {
    throw HttpRequestException(
      statusCode: streamedResponse.statusCode,
      body: '',
      url: url.toString(),
    );
  }

  yield* streamedResponse.stream;
