This app contains an order flow for cupcakes with options for quantity, flavor, and pickup date. The order details get displayed on an order summary screen and can be shared to another app to send the order.
This app demonstrates multiple fragments in an activity, a shared ViewModel across fragments, data binding, LiveData, and the Jetpack Navigation component.
(It's a preorder based app 2 dollar per cupcake any flavour and 3 dollar extra if you choose same day delivery)
