Create-react-native-app: getting error while scanning the QR code, something went wrong

[KrishnaJoshii]

READ THIS FIRST, PLEASE!

The App Store version of the Expo iOS client recently had to remove the QR code scanner from the app. If you intend to load your app on a physical iOS device, please install the latest version of react-native-scripts to your app (yarn add react-native-scripts@latest or npm install react-native-scripts@latest). It adds the "s" key to the interactive prompt, which asks you to enter an email address or phone number and then sends the URL to your device.

Temporary solution

Step 1 : Get the local IPv4 address of your computer
(windows) Type ipconfig in Command Prompt
(Mac) Type ifconfig -a in Terminal

Step 2 : Create a QR code with text exp://YOUR_LOCAL_IP_ADDRESS:19000
You can create QR code on websites like these

Step 3 : Scan the QR Code
