[agconnect_remote_config] error: cannot find symbol import io.flutter.plugin.common.PluginRegistry.Registrar

With Flutter version 3.29.0 Registrar API has been removed. Library should be updated to use the FlutterPlugin API instead.

It is about deprecation of v1 api's. At this point you need to remove them by your own copy or waiting for an update from developers, and the best advice i can give is try to remove those deprecated api's. Because they removed documentation for flutter about this package. Another way is use REST API for linking your app to Cloud DB.
