Description

This introductory project serves as a foundation for exploring the Dart programming language. It focuses on essential concepts and techniques that form the building blocks for more complex Dart applications.

Objectives

This project aims to solidify your understanding of core Dart programming concepts, including:

• Output using the print() function
• Variables and their usage
• Basic data types (strings, integers, doubles)
• Assertions for code validation
• Simple conditional logic for decision-making

Description

This Dart project showcases a collection of functions to demonstrate practical applications of core Dart concepts, including variables, conditional statements, loops, and recursion. The code explores essential programming techniques while adhering to Dart best practices.

Objectives

• Function Fundamentals: Grasp the concept of functions as reusable blocks of code that perform specific tasks. Understand how to define functions, pass arguments, and return values.
• Problem Decomposition: Develop the ability to break a problem down into smaller, manageable functions, improving code readability and organization.
• Control Flow: Practice using conditional statements (if, else if, else) and loops (for, while) to control the execution of code within functions.
• Scope and Abstraction: Understand the concept of variable scope within functions and how functions help promote code abstraction.
• Recursion: Introduce the concept of recursion (functions calling themselves) to solve problems elegantly.
• Practical Applications: Explore how functions are used in practical scenarios such as calculations, string manipulation, data processing, and decision-making.

Description

This project explores the fundamentals of object-oriented programming in Dart. You'll create classes, manipulate properties, implement methods, work with JSON, and apply concepts of inheritance.

Objectives

• Object-Oriented Programming Foundations: Gain a solid understanding of the core principles of OOP, including classes, objects, properties, and methods.
• Encapsulation: Learn how to create classes that bundle data (properties) and related behaviors (methods) together, promoting code organization and maintainability.
• Abstraction: Practice reducing complexity by modeling real-world concepts as classes in your code.
• Inheritance: Explore how to create class hierarchies, enabling code reuse and the modeling of "is-a" relationships.
• Data Serialization/Deserialization: Master the process of converting objects into a format suitable for storage or transmission (JSON) and vice versa.
• Null Safety: Understand Dart's null-aware operators and how to effectively handle potential null values.

• Welcome:

  • Define a custom class (User).
  • Implement methods within a class.

• User to JSON:

  • Work with different data types within a class.
  • Serialize class data into a structured format (JSON).

• Password:

  • Create a class to represent a password.
  • Enforce specific validation rules for data integrity.
  • Control how a class is represented as a string (toString()).

• Private Password

  • Grasp the concept of private members within a class.

• Mutables

  • Use getters and setters to provide controlled access to private members.

• JSON to User

  • Deserialize data (JSON) to create class instances.
  • Provide a meaningful string representation of objects.

• Inheritance

  • Establish relationships between classes to promote code reuse.
  • Combine object properties and behaviors from multiple classes.
  • Handle potential null values and type safety in an inheritance context.

Description

This project delves into the fundamentals of asynchronous programming within the Dart language. You will develop skills in handling delayed operations, fetching data from simulated and external sources, and ensuring code robustness through effective error handling.

Objectives

• Understanding Futures: Grasp the concept of futures as placeholders for results that will be available in the future.
• Async/Await Syntax: Master the use of async and await keywords to streamline asynchronous code and improve readability.
• Error Handling: Learn how to employ try-catch blocks to gracefully handle exceptions that may arise during asynchronous operations.
• Data Fetching: Practice techniques for simulating API calls and work with a real-world API to retrieve data asynchronously.
• Code Organization: Structure asynchronous code in a logical and maintainable manner.

• Users Count: Introduce basic asynchronous programming concepts using futures.
• Get User ID/Get User: Practice working with futures, JSON data, and error handling.
• Greet User: Integrate multiple asynchronous operations, conditional logic, and robust error handling.
• Calcul Total: Build proficiency in coordinating complex asynchronous processes, handling potential exceptions, and working with simulated data.
• Rick and Morty Characters: Apply asynchronous fetching skills with an external API and practice using an established Dart package (http).
