Implementing Stack Navigation

navigation.navigate('Details');

Before the call: Home
After the call:  Home, Details

That one call adds an entry to a list of open screens, and the app shows whatever is last in the list. This behavior is called stack navigation. The last screen added is the first screen removed, which programmers call Last In, First Out (LIFO). You will build a small product catalog with two screens, and then watch that list change with each call.
