How do I use generics in Dart to create a reusable data structure like a Stack<T>?

Generics in Dart allow you to create reusable and type-safe data structures and functions. By defining a class or method with a type parameter, you can work with different data types without sacrificing type safety. For example, a generic Stack<T> class can store elements of any type, such as integers, strings, or custom objects, while ensuring that only the specified type is used throughout the stack's operations. This not only makes your code more flexible and reusable but also helps prevent runtime errors by catching type mismatches at compile time. Using generics, you can build robust and versatile components that integrate seamlessly into various parts of your application.

Here's an example implementation of a generic Stack<T> in Dart:

class Stack<T> {

  final List<T> _stack = [];

  void push(T value) {

    _stack.add(value);

  }

  T pop() {

    if (_stack.isEmpty) {

      throw StateError('No elements in the stack');

    }

    return _stack.removeLast();

  }

  T peek() {

    if (_stack.isEmpty) {

      throw StateError('No elements in the stack');

    }

    return _stack.last;

  }

  bool get isEmpty => _stack.isEmpty;

  int get length => _stack.length;

}

Usage Example:

void main() {

  Stack<int> intStack = Stack<int>();

  intStack.push(1);

  intStack.push(2);

  print(intStack.pop()); // Outputs: 2

  Stack<String> stringStack = Stack<String>();

  stringStack.push('hello');

  stringStack.push('world');

  print(stringStack.peek()); // Outputs: 'world'

}

Explanation:

Generic Type <T>: The Stack class is defined with a generic type parameter T, allowing it to store elements of any type.

Internal List: The _stack list holds the stack elements.

Stack Operations: Methods like push, pop, peek, and isEmpty provide standard stack functionality.

Type Safety: Using generics ensures that the stack is type-safe and can be used with any data type.

 How do I create and use classes and objects in Dart?

 How do I create and use classes and objects in Dart?

In Dart, creating and using classes and objects follows a similar structure to other object-oriented languages. Here’s a basic overview:

1. Creating a Class

A class is a blueprint for creating objects. It defines properties (variables) and methods (functions) that the objects created from the class will have.

Here’s an example of a simple class:

class Person {

  String name;

  int age;

  Person(this.name, this.age);

  void displayInfo() {

    print('Name: $name, Age: $age');

  }

}

In this class:

name and age are properties (also called fields or attributes).

The constructor Person(this.name, this.age) initializes the properties when the object is created.

displayInfo is a method that displays the person's name and age.

2. Creating an Object

Once you’ve defined a class, you can create objects from it. Objects are instances of the class and have access to the class’s properties and methods.

void main() {

  Person person1 = Person('John Doe', 25);

  print(person1.name); 

  person1.displayInfo(); 

}

3. Private Properties and Methods

In Dart, you can make properties and methods private by prefixing them with an underscore (_).

class Car {

  String _model;

  Car(this._model);

  String getModel() {

    return _model;

  }

}

4. Getters and Setters

Getters and setters allow controlled access to class properties. Dart supports automatic getters and setters, but you can also define them explicitly.

class Rectangle {

  double _width;

  double _height;

  Rectangle(this._width, this._height);

  double get area => _width * _height;

  set width(double value) {

    _width = value;

  }

  set height(double value) {

    _height = value;

  }

}

5. Inheritance

In Dart, a class can inherit properties and methods from another class using the extends keyword.

dart

class Animal {

  void makeSound() {

    print('Animal makes a sound');

  }

}

class Dog extends Animal {

  @override

  void makeSound() {

    print('Dog barks');

  }

}

void main() {

  Dog dog = Dog();

  dog.makeSound(); // Output: Dog barks

}

6. Abstract Classes and Interfaces

An abstract class is a class that cannot be instantiated. You use it as a base class that other classes inherit from. It can contain abstract methods (methods without implementation).

abstract class Shape {

  double getArea();

}

class Circle extends Shape {

  double radius;

  Circle(this.radius);

  @override

  double getArea() => 3.14 * radius * radius;

}

void main() {

  Circle circle = Circle(5);

  print(circle.getArea()); // Output: 78.5

}

Summary

Class: A blueprint for creating objects.

Object: An instance of a class.

Constructor: A special method to initialize objects.

Methods: Functions inside a class.

Getters and Setters: Control how you access and set property values.

Inheritance: Reusing and extending functionality from another class.

Abstract Classes: Classes with unimplemented methods, serving as a template for subclasses.

You can use these building blocks to create more complex applications in Dart.

      throw StateError('No elements in the stack');

    }

    return _stack.last;

  }

  bool get isEmpty => _stack.isEmpty;

  int get length => _stack.length;

}

  Stack<int> intStack = Stack<int>();

  intStack.push(1);

  intStack.push(2);

  print(intStack.pop()); // Outputs: 2

My client asked me to create an app for their services. The client had only copywriting and some videos, But they didn't have any design demos. So I have created all of the design demos for them.

There are 20pages for the apps and I was given only the logo and brand guidelines.

> I created the UI / Flutter design first then I showed the work to my client and took modifications and made the revisions.

Initially, I developed only the home page and services pages in 5 days. I got some modifications and revised them in just 1days.

Then in the next 8 days, I have completed the below pages.

Menu Screen

Home Screen

Login Screen

Logout Screen

RatingScreen

Profile Screen

Booking Screen

>> Finally in 15 days I have completed the banking app
