Implementation
Stream<List<int>> fetchStreamed({CdnFormat? format, int? size}) async* {
assert(format != CdnFormat.gif || isAnimated, 'Asset must be animated to fetch as GIF');
final request = _getRequest(format ?? defaultFormat, size);
final rawRequest = request.prepare(client);
final rawResponse = await client.httpHandler.httpClient.send(rawRequest);
if (rawResponse.statusCode < 200 || rawResponse.statusCode >= 300) {
throw HttpResponseError.fromResponse(request, rawResponse);
}
yield* rawResponse.stream;
}
