Why not change the createSession to return Future<int?>?

Future<int?> createSession(Session session) async {
    try {
      final response = await http
          .post(Uri.parse('$serverUrl$sessions'),
              headers: headers,
              body: json.encode(
                session.toJson(),
              ))
          .timeout(Duration(seconds: _timeoutTimerInSeconds));
           if (response.statusCode == 201) {
            var body = json.decode(response.body);
            return body['id'] as int;
          } else {
            print("Error: Unexpected response code ${response.statusCode}");
            print("Response body: ${response.body}");
          }
    } on TimeoutException {
      print("Error: Request timed out.");
    } on http.ClientException catch (e) {
      print("HTTP Client Exception: $e");
    } catch (e) {
      print("Error : ${e}");
    }
    return null;
  }

So then the Utils.createNewReports is simplified into:

Session session = Session(
          session_ID: sessionId,
          user: userUUID,
          session_start_time: DateTime.now().toUtc().toIso8601String());

print(language);
session.id = await ApiSingleton().createSession(session);

What do you think?

I agree, I've applied your changes, except the line

Session session = Session(

because this would cause a bug, since session is not a new variable but a static class variable
