Fetch data from the Soap Webservice

Fetching data from the Web service is necessary for most apps. Thankfully, Dart and Flutter provide tools, such as the http package, for this type of work

1. Add the Packages  as a dependency and make necessary imports respectively

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  http:
  xml:
  html_unescape:

Run flutter packages get to download the package

 2.  Add import statements to import necessary packages in your dart file.

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:http/http.dart' as http;
import 'dart:convert';
import 'package:async/async.dart';
import 'package:xml/xml.dart' as xml;

3. Make a network request
Put this function in your dart file 
Future<int> _isGetdata(String number, String Number) async {
  String url ="url/method_name?Parameter1="1"&Parameter2="2"";
  print(url);
  var req = await get(url);
  print(req.body);
  var jsondata = json.decode(xml.parse(req.body).children[2].children[0].toString());
  print(jsondata);
  return jsondata;
}
In this the return type jsondata is integer type because in future<int> we define integer

Future is a core Dart class for working with async operations. A Future object represents a potential value or error that will be available at some time in the future

YEAH! Now you’ve got a function that fetches a data from the Soap Webservice.
