I try to receive chunk of data that send from api, and it work if I run command flutter test test/widget_test.dart it enter in loop many time but if I debug my flutter app it not get stream it get whole response and it enter loop just one time

Future<void> response(String body) async {
    var client = http.Client();
    Map<String, String> headers = {
      "Accept": "application/json",
      'Content-Type': 'application/json',
      'Connection': 'Keep-Alive',
      'Authorization': "Bearer 'mocktoken'"
    };
    try {
      var request = http.Request("POST",
          Uri.parse("https://localhost:5001/api/ChatBot/chatbot_requestquestion"));
      request.body = body;
      request.headers.addAll(headers);
      var response = await client.send(request);
      await for(var value in response.stream.transform(utf8.decoder)){
        print(value);
    }
      // Process the stream of response data in chunks
    //   print(response.headers);
    //   response.stream.transform(utf8.decoder).listen((chunk) {
    //     print(chunk); // Adding each chunk to the stream
    //   }, onDone: () {
    //     client.close();
    //   }, onError: (error) {
    //     print('Error: $error');
    //     client.close();
    //   }, cancelOnError: true);
     } catch (e) {
       print(e);
       throw e;
    }
  }

void main() async {
  await response();
}

I want it work in my app
