Screens

A screen is a "route" which will be added to the Stack navigator. Each screen could have its own screens folder. The structure of each folder should be as follows:

1. index.tsx
2. presenter.tsx
   • The main logic and export of the component.
3. styled.tsx
   • Any internal styled emotion components and stylesheets the presenter.tsx file may use.
   • NOTE: Avoid the react-native/StyleSheet if possible.

Nested Folders:

Each specific screen folder should mimic the root level (src) folder, for any screen-specific needs. For example:

• components: If there are any modular components that are specific to this screen's presenter.
