? Factory Method
-
Create Enum product_type.dart & location_type.dart
enum ProductType {
burger,
pizza,
chicken,
chips,
}
enum LocationType {
hanoi,
danang,
hochiminh,
}
- Create Abstract Class - food.dart
import 'package:flutter_pizza_store/src/events/location_event.dart';
import 'package:flutter_pizza_store/src/models/product.dart';
abstract class Food {
void initial() {}
void filterByLocation(LocationType location) {}
List<Product> products() {
return [];
}
}
- Create Concrete Class - burger.dart, similar with pizza.dart, chicken.dart, chips.dart
import 'package:flutter_pizza_store/src/events/location_event.dart';
import 'package:flutter_pizza_store/src/events/product_event.dart';
import 'package:flutter_pizza_store/src/models/food.dart';
import 'package:flutter_pizza_store/src/models/product.dart';
import 'package:flutter_pizza_store/src/repository/product_repository.dart';
class Burger implements Food {
List<Product> _products = [];
@override
void initial() {
allProducts.forEach((product) {
if (product.type == ProductType.burger) _products.add(product);
});
}
@override
void filterByLocation(LocationType location) {
_products
.where((e) {
return e.location != location;
})
.toList()
.forEach((_products.remove));
}
@override
List<Product> products() {
return _products;
}
}
- Create Factory Class - food_factory.dart
import 'package:flutter_pizza_store/src/events/product_event.dart';
import 'package:flutter_pizza_store/src/models/burger.dart';
import 'package:flutter_pizza_store/src/models/chicken.dart';
import 'package:flutter_pizza_store/src/models/chips.dart';
import 'package:flutter_pizza_store/src/models/food.dart';
import 'package:flutter_pizza_store/src/models/pizza.dart';
class FoodFactory {
static Food getFood(ProductType type) {
switch (type) {
case ProductType.burger:
return Burger();
case ProductType.pizza:
return Pizza();
case ProductType.chicken:
return Chicken();
case ProductType.chips:
return Chips();
default:
return Burger();
}
}
}
