Http Timeout does not work for MultiPart request

Here is my MultiPartRequest code

```
var request =
http.MultipartRequest("POST", Uri.parse(EMPLOYEE_PUNCH_IN_URL));

request.fields['uid'] = userId;
request.fields['location'] = location;
request.fields['punchin_time'] = punchInTime;
request.fields['punchin_location_name'] = address;

var multiPartFile = await http.MultipartFile.fromPath(
"photo", imageFile.path,
contentType: MediaType("image", "$extension"));
request.files.add(multiPartFile);
http.StreamedResponse response = await request.send();

var responseByteArray = await response.stream.toBytes();

employeePunchInModel = standardSerializers.deserializeWith(
EmployeePunchInModel.serializer,
json.decode(utf8.decode(responseByteArray)));
......
```

know how to set timeout to a normal http request. I have followed this link

[https://stackoverflow.com/questions/51487818/set-timeout-for-httpclient-get-request]

I have tried adding timeout function in following ways but it won't work and my request gets completed

1.
```
var multiPartFile = await http.MultipartFile.fromPath(
"photo", imageFile.path,
contentType: MediaType("image", "$extension")).timeout(const Duration(seconds: 1));

```
2.
`http.StreamedResponse response = await request.send().timeout(const Duration(seconds: 1));
`
3.
`var responseByteArray = await response.stream.toBytes().timeout(const Duration(seconds: 15));
`
But none of the above timeout works.
