🧩 Any Custom Plugins Developed?

As of this documentation version, no custom Flutter plugins have been developed specifically for the Kleber App. However, the application does include custom Dart utility classes, such as:

end_points.dart – Centralized configuration for API environments
Custom form handlers and PDF utilities for validating

These are not plugins, but they serve similar modular purposes within the app.
