        print(jwt.isExpired);
      });
    });

once a token is generated it can be used with google api ...

import "package:google_analytics_v3_api/analytics_v3_api_console.dart";

Analytics analyticsClient = new Analytics(new oauth2.SimpleOAuth2Console(project, "", jwt.accessToken));
analyticsClient.makeAuthRequests = true;
