You will develop a new app to help users track weather conditions for different locations. The app should include the following functionalities:

Network calls to fetch weather data from an API.

Navigation between different screens to display weather details.

Local data storage using the Room library.

Implementation of MVVM architecture and repository pattern for better code organization and data management.

Features and Implementations
