+This error likely indicates that you haven't correctly entered the command option along with its value. Double-check that all required information has been entered. If everything is correct and you're still encountering the error, it might be due to using an outdated version of the FlutterFlow CLI. To resolve this, you can update to the latest version by running the installation command:
+```
+dart pub global activate flutterflow_cli
+```
+This should update the CLI and fix the issue.
