Stream.fromIterable bad state already been listened

[dalton5]

Hi,

I have an issue. I follow the example exactly as explained in the example file for post bytes.

I use dio 4.0.0

But I always have the error below:

My code is:

    ` var content = json.encode(queryParameters);
      List<int> bodyBytes = utf8.encode(content);
      
      var resp = await dio.post(
        endpoint,
        data: Stream.fromIterable(
            bodyBytes.map((e) => [e])), //create a Stream<List<int>>
        options: Options(
          headers: {
            Headers.contentLengthHeader:
                bodyBytes.length, // set content-length
          },
        ),
      );`
