        requestencryptionKey: '8E41C78439831010F81F61C344B7BFC7',
        requestsaltKey: '8E41C78439831010F81F61C344B7BFC7',
        responsehashKey: 'KEYRESP123657234',
        responseencypritonKey: '8E41C78439831010F81F61C344B7BFC7',
        responsesaltKey: '8E41C78439831010F81F61C344B7BFC7',

Getting Response From Webview

 @override
  void initState() {
    super.initState();
    flutterWebViewPlugin.onUrlChanged.listen((String url) {


             print(url);

      if (url.contains('/response.php')) {

         var substringfromurl = url.substring(0,url.indexOf('?'));
         var urlarray = substringfromurl.split('&').map((String text) => Text(text)).toList();
         print(urlarray);

            // var atompay = new AtomPaynetz(
            //     login: '192',
            //     pass: 'Test@123',
            //     prodid: 'NSE',
            //     amt: '100.00',

            //     custacc: '0',
            //     udf1: 'Test Name',
            //     udf2: 'test@test.com',
            //     udf3: '9999999999',

            //     mode: 'uat');
              // var validate =  atompay.validateSignature(
              //                     mmp_txn,
              //                     mer_txn,
              //                     f_code,
              //                     prod,
              //                     discriminator,
              //                     amt,
              //                     bank_txn,
              //                     signature
              //                   );
        flutterWebViewPlugin.close();
