The Dependency Rule Explained

Grasp the fundamental Dependency Rule, which dictates that dependencies can only flow inwards, ensuring core business logic remains isolated.

The Core of Clean Architecture

Welcome to our lesson on the Dependency Rule! This principle is the cornerstone of Clean Architecture, ensuring your core business logic remains isolated and independent.

It's all about directing the flow of dependencies in your application in a very specific way.

Dependencies Flow Inwards

The fundamental idea is simple: dependencies can only flow inwards. This means outer layers of your architecture must depend on inner layers, but inner layers must never depend on outer layers.

Think of it as a one-way street, always leading towards the center of your application's logic.
