API to Integrate native mobile app with this WordPress plugin

[muraliwebworld]

New feature to Integrate Native mobile apps like Flutter mobile app with this WordPress plugin

New API to send push notification subscription from Native mobile apps like Flutter mobile app to WordPress backend and to send push notifications from WordPress to Native mobile app using Firebase.

Generate secret key in mobile app tab to communicate between mobile app(in Integrate app api tab plugin settings)
REST api to send subscription token from Mobile Flutter app using WebView to this WordPress plugin to store it in WordPress db to send push notification whenever new activities/post are published.
Note:- All REST api code is already included in the code, below is only for reference as guide,

REST API using POST method, to send push notification in secured way using AES 256 cryptography encryption method to avoid spams

REST API url post method to send push notification https://domainname.com/wp-json/PNFPBpush/v1/subscriptiontoken

Input parameters in body in http post method in Flutter APP, token – it should be encrypted according to AES 256 cryptography standards,

Following is sample code in dart Flutter AES 256 encryption and hash generation using AES 256 cryptography to send push notification subscription token in encrypted manner to this plugin - WordPress backend

Refer More details are in readme section in plugin description page

Sample DART code in Flutter mobile app showing how to do AES 256 encryption in Flutter app and to decrypt in PHP WordPress

String strPwd = "16234hgJKLmllpdcd09b2bc37293"; //secret key generated in step 1 above

      GlobalData.pushtoken = token.toString();

      final iv = EncryptPack.IV.fromLength(16);

      final key = EncryptPack.Key.fromUtf8(strPwd); //hardcode

      final encrypter = EncryptPack.Encrypter(EncryptPack.AES(key, mode: EncryptPack.AESMode.cbc));

      final encrypted = encrypter.encrypt(token.toString(), iv: iv);

      var hmacSha256 = CryptoPack.Hmac(CryptoPack.sha256,ConvertPack.utf8.encode(strPwd)); // HMAC-SHA256

      var hmacstring = hmacSha256.convert(ConvertPack.utf8.encode(token.toString()));

      var encryptedsubscription = encrypted.base64+":"+iv.base64+":"+hmacstring.toString()+":"+hmacstring.toString();
