byteData method

@override Future<ByteData> byteData([ int start = 0, int? end ])

Reads content body as bytes and returns a future of ByteData.

Optional start and end parameters define a range to be read. It's required that 0 ≤ start ≤ end ≤ contentLength. See also ByteData.sublistView for reference.

Implementation

@override
Future<ByteData> byteData([int start = 0, int? end]) async {
  try {
    final res = response;
    if (res is http.StreamedResponse) {
      return ByteData.sublistView(await res.stream.toBytes(), start, end);
    } else {
      return ByteData.sublistView(
        (res as http.Response).bodyBytes,
        start,
        end,
      );
    }
  } on Exception catch (e) {
    throw ClientException.readingBytesFailed(e);
  }
}
