Sports Team Detail
A demo showing the teams squads and player information
Description
This is a demonsration of the basic functionality of sports information app. For this exercise, we’ll only focus on the Squad section of the Team detail view.
Architecture
Although this is a very small and basic app, I want to demonstrate that we can easily use CLEAN Architeture and follow the SOLID principles. This way we can avoid tight coupling and will be able to add/remove functionality without the need to modify several modules.

We don’t have an API for this demo but we can create the Use Cases so we can design the features and user flow
