Theming

Owl follows Material Design, customizing colors, typography and shapes. These come together in Owl's multiple themes, one for each color scheme. Additionaly, Owl supports image and elevation theming, providing alternate images/elevations in light/dark themes.

Common UI

Compose makes it simple to create a library of components and use them throughout the app. See:

• CourseListItem is used on both the My Courses screen and in the related section of the Course Details screen.
• OutlinedAvatar is used on both the Featured Courses screen and the Course Details screen.

Utilities

Owl implements some utility functions of interest:

• Lazy layouts - specifically LazyColumn and LazyRow, passing item keys and using animateItemPlacement().
• Window insets are provided by the Compose Foundation library.
• NavGraph models navigation within the app using Jetpack Navigation.

Data

Domain types are modelled in the model package, each containing static sample data exposed using fake Repos objects.
