Feature module

The categories feature module includes all the presentation logic required to display the categories screen. If you need to include this module, add it to your build.gradle:

implementation ("com.poqstudio:catalogue.categoriesv2:$VERSION_NAME")

Architecture

• CategoriesActivity is the entry point to the Categories screen.
• CategoriesFragment is the fragment used in the bottom bar navigation.
• CategoriesView controls the visibility of the elements in the screen. It also initialises CategoriesRecyclerViewAdapter with the information received from CategoriesViewModel and handles the navigation of the screen.
• CategoriesViewModel is the main ViewModel.
• CategoryItemViewModel is the ViewModel for each category row.
• CategoriesStore handles the categories expansion/collapse.
