We'll use React Native NetInfo to detect whether the user's device is offline. If the device is offline, we will show a full screen "you are offline" message.

Resources:

• React Native NetInfo: https://github.com/react-native-netinfo/react-native-netinfo

Expo:

• If using Expo, install the library with expo install @react-native-community/netinfo as per the docs

Checkpoint: Show a full screen error when the app is offline
