Flutter Lesson 15: Refactoring to a Cleaner Architecture (Repository Pattern)
In this lesson, we refactor our Todo app to a cleaner and more scalable architecture.
We introduce a repository layer, separate responsibilities more clearly, and prepare the codebase for future growth — without changing the app’s behavior.
This lesson is the first hands-on step into intermediate Flutter development.
In this lesson you will learn:
Why architecture matters at the intermediate level
How to introduce a repository layer
How to separate data, logic, and UI
How to refactor without breaking functionality
