ChatGPT Will Destroy Your Shitty Medium Coding Blog
As the majority of Medium coding articles are diluted, clickbaity garbage, I hypothesize that ChatGPT will render these authors (including myself) entirely obsolete within the next year. It’s time to find another way to scam people out of time that could have been spent actually being productive.
I used the following ChatGPT Query:

Design Patterns in Programming with Dart
Design patterns are a fundamental aspect of software engineering that help developers create maintainable, scalable, and readable code. They are time-tested solutions to common programming problems and can be applied to any programming language, including Dart. In this article, we will explore some of the most commonly used design patterns in Dart and discuss how they can improve the structure and organization of your code.
What Are Design Patterns?
Design patterns are recurring solutions to common software design problems. They provide a structured approach to solving problems, making it easier to write code that is both maintainable and extensible. Design patterns are not rigid templates but rather guidelines that help developers make informed decisions about how to structure their code.
Creational Design Patterns
1. Singleton Pattern
The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance. In Dart, you can implement the Singleton pattern like this:
class Singleton {
static Singleton _instance;
factory Singleton() {
_instance ??= Singleton._internal();
return _instance;
}
Singleton._internal();
}
2. Factory Method Pattern
The Factory Method pattern defines an interface for creating objects but lets subclasses alter the type of objects that will be created. Here’s an example in Dart:
abstract class Product {
void showInfo();
}
class ConcreteProductA implements Product {
@override
void showInfo() {
print("Product A");
}
}
class ConcreteProductB implements Product {
@override
void showInfo() {
print("Product B");
}
}
abstract class Creator {
Product factoryMethod();
}
class ConcreteCreatorA implements Creator {
@override
Product factoryMethod() {
return ConcreteProductA();
}
}
class ConcreteCreatorB implements Creator {
@override
Product factoryMethod() {
return ConcreteProductB();
}
}
Structural Design Patterns
3. Adapter Pattern
The Adapter pattern allows the interface of an existing class to be used as another interface. It is often used to make existing classes work with others without modifying their source code. In Dart:
class OldClass {
void doSomethingOld() {
print("Doing something old");
}
}
class NewInterface {
void doSomethingNew();
}
class Adapter implements NewInterface {
final OldClass _old = OldClass();
@override
void doSomethingNew() {
_old.doSomethingOld();
}
}
4. Decorator Pattern
The Decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting the behavior of other objects from the same class. Dart example:
abstract class Component {
void operation();
}
class ConcreteComponent implements Component {
@override
void operation() {
print("Concrete Component");
}
}
class Decorator implements Component {
final Component _component;
Decorator(this._component);
@override
void operation() {
print("Decorator Before");
_component.operation();
print("Decorator After");
}
}
Behavioral Design Patterns
5. Observer Pattern
The Observer pattern defines a one-to-many dependency between objects, where one object (the subject) maintains a list of dependents (observers) that are notified of any changes to the subject’s state. In Dart:
class Subject {
List<Observer> _observers = [];
void addObserver(Observer observer) {
_observers.add(observer);
}
void removeObserver(Observer observer) {
_observers.remove(observer);
}
void notifyObservers() {
for (var observer in _observers) {
observer.update();
}
}
}
abstract class Observer {
void update();
}
6. Strategy Pattern
The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows the algorithm to vary independently from the clients that use it. Dart example:
abstract class Strategy {
void execute();
}
class ConcreteStrategyA implements Strategy {
@override
void execute() {
print("Executing Strategy A");
}
}
class ConcreteStrategyB implements Strategy {
@override
void execute() {
print("Executing Strategy B");
}
}
class Context {
Strategy _strategy;
Context(this._strategy);
void executeStrategy() {
_strategy.execute();
}
}
Conclusion
Design patterns are powerful tools in a programmer’s toolkit. They improve code maintainability, extensibility, and readability. While we discussed only a few design patterns in Dart, there are many more to explore. Choosing the right design pattern for your specific problem is crucial, and understanding their principles can significantly enhance your software development skills. Whether you’re building a small Dart application or a complex software system, design patterns can help you create efficient and elegant solutions.

This AI generated article is accurate, to the point, and not clickbaity at all. It provides useful information without leading the reader down a rabbit hole of rectum-esque opinions or self-aggrandizing, prose-like filler content. It’s time to adapt to the Brave New World. If you happen to be in the business of writing these low-quality articles, it might be time to pursue your true calling as a Nigerian Prince.
