narayan_system_core

The brain of the Narayan Farms business system. A pure orchestration layer that coordinates all domain packages without UI, database, or Firebase.

📌 What is this package?

narayan_system_core is a system-level orchestration package that connects all core business domains:

Ordering

Supply & Inventory

Delivery & Workforce

Loyalty / Streak / Levels

It does not contain business rules and does not contain UI or infrastructure.

Think of it as:

“Traffic controller for your business logic.”

🚫 What this package is NOT

This package contains NO:

❌ UI (Flutter widgets, screens)

❌ Firebase / database code

❌ HTTP / REST clients

❌ Business logic duplication

❌ Direct domain coupling

All logic lives inside domain packages. This package only coordinates them.

Time Injection (No DateTime.now())

Event-Driven System Design

Each domain is independent and testable.
