What's missing ?

Since we had a very busy period at my current job, I could only spare a few hours for this project. While doing this, I installed the general structures, but some features were missing such as refresh handler and favorite queries.

What could be better ?

Of course, this repo could not be prepared in the best way due to the highly limited time and lack of motivation. Here are some steps to make this repo more professional;

• App State should be added in order to drive navigation events and handle errors with a generic way
• Store api information and base url more appropriate way
• Usecases could be added to domain layer
• Multimodule structure could be used
• Some data mappers and result classes could be implemented to data layers (also error handling)
• Also data layer data classes should be converted to UI data classes for UI layer
• With multimodule structure, Compose Navigation will be implemented better, in accordance with the SOLID principles
• Unit tests and Portrait mode could be added
• Queries from data layer to ui layer could be handled with flows.
• Network data classes could be more simple, unnecessary fields implemented

Note

The UI-UX never cared
