            React-native-vision-camera can't access to normal camera in back
            Asked 2022-Mar-07 at 07:02

            i am trying to use 'normal' camera on my iphone 11 pro. I use react-native-vision-camera. When i run this code:

            ANSWER

            Answered 2022-Mar-07 at 07:02

            tl;dr - Single-lens smartphone cameras commonly have a wide-angle lens of roughly 22mm and 30mm equivalent. So basically, you would want to choose wide-angle, as this is the "normal" type.

            based on the react-native documentation, there are three Identifiers for a physical camera (one that exists on the back/front of the device):

            "ultra-wide-angle-camera" | "wide-angle-camera" | "telephoto-camera"

            "ultra-wide-angle-camera": A built-in camera with a shorter focal length than that of a wide-angle camera. (focal length between below 24mm)

            "wide-angle-camera": A built-in wide-angle camera. (focal length between 24mm and 35mm)

            "telephoto-camera": A built-in camera device with a longer focal length than a wide-angle camera. (focal length between above 85mm)

            now that we have that settled, let's take a look at cameras' focal lengths that are equivalent to phone cameras' focal length (resource)

            Camera type Focal length Angle-of-view Wide-angle 22mm to 30mm ~84° to ~62° Telephoto 50mm to 80mm ~40° to ~25° Ultrawide-angle 12mm to 18mm ~112° to ~90° Periscope 103mm to 125mm ~20° to ~16°

            what is considered a "normal" focal length is 35mm, so you should choose wide-angle since it is the closest (and eventually with the angle of view the user might be even closer to 35mm), further more the wide-angle is the most common focal-length for phone camera lens

            1) First off Firebase/MLVisionTextModel is deprecated (FirebaseMLVisionTextModel has been deprecated in favor of MLKitTextRecognition). You can read the migration guide here (https://developers.google.com/ml-kit/migration)

            2) If you ever have errors like was resolved to x.x.x, which depends on Firebase/CoreOnly (= x.x.x) A lot of times you can fix this by adding this below at the very top of your PodFile to specify what version to use.

            Using react-native-vision-camera, I saw that there is a path for the image. It seem readable by react native tag.

            I attempted to upload using this path (I used both file:// for android, and same for IOS), however it failed. Each time the file was detected as "jpeg" or "jpg" but I couldn't access it.

            After downloading (From S3 amazon where I uploaded) and converting the jpg to txt, I only find the "file://path".

            How do you implement React-native-gesture-handler with React Navigation 6.x Native Stack Navigator (RN>0.6)?
            Asked 2021-Nov-30 at 08:25

            So, I am building a prototype android app as an internship project for a startup in React Native v0.66. I was new to RN but not React when I set up the project. My choice for navigation fell upon React Navigation 6.x and their Native Stack Navigator because it performs better than the regular Stack Navigator, although is not as customizable according to docs.

            Now I want to use react-native-gesture-handler in my project. According to their docs,

            "If you are using a native navigation library like wix/react-native-navigation you need to follow a different setup for your Android app to work properly. The reason is that both native navigation libraries and Gesture Handler library need to use their own special subclasses of ReactRootView.

            Instead of changing Java code you will need to wrap every screen component using gestureHandlerRootHOC on the JS side. This can be done for example at the stage when you register your screens."

            I suppose this includes React Navigation-Native Stack Navigator as well? There is code example of how to implement RNGH with wix/react-native-navigation, but none, anywhere, for my case:

            How to hot reload a development package in an Expo app example nested folder?
            Asked 2021-May-28 at 20:54

            Is it possible to an Expo app example to load a module located in the parent folder AND to see changes in the example app when i rebuild the package (with tsc -w to rebuild on any saved files)? I precise that the module is not publish on npm yet.

            I've already succeed to do that using monorepo architecture with yarn workspaces and expo-yarn-workspaces package. But what about the case when you don't want to publish your package like a monorepo?

            For example, in this repo https://github.com/cuvent/react-native-vision-camera There is an example RN app in bare workflow and in its package.json there is no mention of the developed package (meaning that it's not installed like a normal dependency). But in the app src/App.tsx, the package is used like that :

            Finally, I've found something that works for me. You can find my config for metro if you want here: https://github.com/grean/react-native-metro-config-app-example With it, you can access the parent component from the expo app, modify it and immediately see the hot-reload changes. Create a file metro.config file in your expo root app directory with that code inside:
