Question

A canvas app has a Home screen with a gallery of customer records and a Details screen. When a user selects a customer in the gallery, you must open the Details screen and display that specific customer's data. The Details screen must continue to show the correct record even if the user navigates away and returns, and you want to avoid relying on the gallery's Selected property after navigation. Which approach best accomplishes this?
