Remove Debug Tag from Flutter App

**Description:**

We need to remove the `debug` tag from the Flutter app to ensure it is ready for production. This will help us avoid any potential security risks and ensure that the app behaves as expected in a release environment.

**Tasks:**
1. Locate the `debug` tag in the relevant files:
- Check `pubspec.yaml` for any debug configurations.
- Review the `main.dart` file for any debug-specific settings.
2. Ensure that the app is configured to run in release mode without the debug tag.

**Acceptance Criteria:**
- The `debug` tag is removed from all relevant configurations.
- The app builds and runs correctly in release mode.
- No debug information is displayed in the app.
