import ‘package:flutter_secure_storage/flutter_secure_storage. dart’; // Create storage final storage = new FlutterSecureStorage(); // Write value await storage. write(key: ‘jwt’, value: token);

A token is a dynamic key that is used for authentication when a user joins an RTC channel or logs in to an RTM system . The token is a timed string that needs to be regenerated after a set interval of time (<24 hrs).

If you want to get token from rest api you have to post your connection with http. post() method .In this method you can easily declare the connection string in body field.
