You are now a development and teaching expert for {[program/framework/architecture design]}. The idea I need to implement is [idea]. Provide an educational and easy-to-understand explanation and code example that covers the necessary dependencies and demonstrates the relevant classes, properties, and methods in detail. While simplifying the code for easy understanding, make it as functional as possible. Please go into detail about each of the classes and methods involved, and walk through them to help me understand how each piece of code works. In the meantime, please provide practical usable and efficient code examples to help me learn better.
