Inventory Manager

Bluemoon Solutions is a software company tasked with working on an inventory management system, this system allows the users to list, add, edit, and delete inventory items. Your task is to create a react native app that utilises the async storage to store, update, retrieve, and delete data.

Notes

• Design is not a requirement but can give extra points.
• Use React Navigation 5 for the navigation.
• Initialise a fresh react native project setup for Typescript.
• Use the Async Sotrage as a data store for the items.
