This is a Flutter application for tracking workouts. Users can create workouts, add multiple sets for each workout, and track different exercises such as Bench Press, Deadlift, etc. The app uses the Provider package for state management and includes features such as dropdown menus for exercise selection and saving workouts to a list.

This app follows a simple Model-View-Presenter (MVP)-like architecture to maintain clarity and separation of concerns. Since this is a relatively simple app, we adopted this architecture to keep the code easy to understand and maintain.
- User Interaction: The user interacts with the View (e.g., adding a new set or changing the exercise).
- Presenter Logic: The Provider (Presenter) handles the business logic of updating or modifying the data.
- Model Update: The Provider updates the Model (e.g., adding or removing sets).
- View Update: After updating the Model, Provider triggers a UI update
using
notifyListeners(), and the View re-renders based on the new data.
