I don't know about the native implementation
react-native-camera
uses as most of this could be done in js (custom view for the tap, gesture) 😁 really just need a prop like focusPosition={{x: 0, y: 0}}

This functionality can be included in your project through
react-native-vision-camera
using Development Builds (https://docs.expo.dev/development/getting-started/) and EAS Build (https://docs.expo.dev/build/introduction/). We have no further plans to add this to the Expo core SDKs.Kim Brandwijk

I think this is a basic feature to a camera / barcode scanner.
For the best compatibility to basic feature of an app, I wish to stay with expo-camera instead of creating my own package that might increase the difficulty when updating sdk version.
Really hope the expo team can implement this feature! I think they are related to the followings for native implementation.

Hi , I would need this feature also. Any one did try to implement this feature alone ?
Michael Wood
If you want this before it's implemented in expo-camera, you might want to try
react-native-vision-camera
for this:RN Vision Camera would require building with EAS Build. (Either locally on your machine, or on Expo's build service.)

Michael Wood: Thank you for the tip! I am working on setting up react-native-vision-camera now in new environment

Seth Kaufman: is RN Vision better than expo version? How are the quality of the pictures?
Seth Kaufman
Logan: Hi, I ended up just staying in the expo environment for the app I was making at the time, so I'm not sure how well RN Vision works... I've finally moved away from expo altogether to be able to use other packages on my current project.
Logan
Seth Kaufman: Hi, thank you for taking the time to reply to me. I think I'll move off of expo camera as RN vision seems like it'll allow you to select between different camera. Expo has been frustrating lately as they are a bit behind on react version and EAS (as good as it looks) is very over priced
Michael Wood
Seth Kaufman: Hi. One of the big features of EAS Build is to allow you to use other packages in an Expo app.
Michael Wood
Logan: EAS Build can be used on your own machine with
eas build --local ...
Also, they are planning to offer a free tier "soon".

Michael Wood: Any idea by when Expo is going to implement tap-to-focus in Expo camera?
Seth Kaufman
This would be a great and necessary addition to expo-camera
Cyril Diagne
Oh yes please! This is the most requested feature in our app!
José Renato baroni
That would be perfect...

Is there a way to automatically place or focus any Barcode components in the expo?
Varun Raja
this will be very useful for barcode scanning functionality as well. If you have a bunch of barcodes on a paper, the current barcode scanning is very ambiguous.

Cool! Looking forward to see this feature is on the Expo!
Awesome Expo!
