Entity Design Patterns

All entities follow these consistent patterns:

Immutability

  • All fields are final
  • Constructor uses const when possible
  • copyWith() method for creating modified copies

Value Equality

  • Proper == operator override
  • hashCode override using Object.hash()
  • toString() method for debugging

Business Logic

  • Computed properties (getters) for derived values
  • Boolean checks (e.g., isActive, isExpired)
  • Helper methods for common operations

Type Safety

  • Enums for status/type fields with displayName getters
  • Nullable types (?) where appropriate
  • List/Map types for collections and JSONB fields

Documentation

  • Comprehensive documentation comments
  • Feature-level context
  • Field descriptions

Database Field Mapping

All entities map 1:1 with database schema:

  • varchar → String or String?
  • numeric → double
  • integer → int
  • boolean → bool
  • timestamp → DateTime
  • date → DateTime
  • jsonb → Map<String, dynamic> or typed classes
  • inet → String?
  • text → String?
  • Arrays → List<T>

Key Features

ERPNext Integration

Many entities include ERPNext reference fields:

  • erpnextItemCode (Product)
  • erpnextSalesOrder (Order)
  • erpnextInvoice (Invoice)
  • erpnextPaymentEntry (PaymentLine)
  • erpnextQuotation (Quote)
  • erpnextEntryId (LoyaltyPointEntry)

Address Handling

Reusable address classes for different contexts:

  • Address (Order entity)
  • DeliveryAddress (Quote entity)
  • Both with JSON serialization support

Attachment Management

List-based attachment fields for multiple files:

  • User attachments (ID cards, licenses)
  • Project photos (before/after)
  • Points record invoices
  • Design request references
  • Chat message files

Audit Trail Support

  • Creation timestamps (createdAt)
  • Update timestamps (updatedAt)
  • User tracking (createdBy, processedBy, reviewedBy)
  • Change tracking (AuditLog entity)

Next Steps

These domain entities are ready for:

  1. Data layer model creation (extending entities with JSON serialization)
  2. Repository interface definitions
  3. Use case implementation
  4. Provider/state management integration

All entities follow clean architecture principles with no external dependencies.
