Trying to register a new user on my table on Backendless using Flutter

I am getting this error when I try to run the application on my Android smartphone:

“PlatformException(2002, Version is disabled or provided wrong application info (application id or secret key), Version is disabled or provided wrong application info (application id or secret key), null)”

Please assist what could be the reason I am getting this error?
