Feature module

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

implementation ("com.poqstudio:checkout.cart:$VERSION_NAME")

Architecture

• CartActivity is the entry point to the Cart screen.
• CartFragment handles the action bar menu items (edit/done button).
• CartView controls the visibility of the elements in the screen. It also initialises CartRecyclerViewAdapter with the information received from CartViewModel and handles the navigation of the screen.
• BaseCartItemViewHolder is the view holder for the cart item block.
• CartItemViewModel is the ViewModel for the cart item block.
• BaseVoucherTitleCartItemViewHolder is the view holder for the vouchers section title.
• BaseAppliedVoucherCartItemViewHolder is the view holder for the applied vouchers block.
• AppliedVoucherCartItemViewModel is the ViewModel for the applied vouchers block.
• BaseAddVoucherCartItemViewHolder is the view holder for the add vouchers block.
• AddVoucherCartItemViewModel is the ViewModel for the add vouchers block.
• BaseCustomCartItemViewHolder is the view holder for your custom blocks.
• CartViewModel is the main ViewModel that coordinates the rest of the ViewModels.
• CartStateViewModel is responsible for executing the domain interactors and exposes the state of the screen.
• CheckoutPanelViewModel receives the cart model and exposes the necessary data to present CheckoutPanelView.
• CartStore handles the edit mode and its actions, keeping the copy of the edited items.
