react-native-qrcode | 基于 React Native Camera 实现二维码扫描

upgraded Expo SDK along with referring to the “Deprecations, renamings, and removals” section of the SDK 40 upgrading post from SDK39 to SDK40 and got an error.

I am using 'react-native-qrcode' library and trying to create a QR Code, it seems to be working up until the point I want to make it take 100% of it's own container.

I've tried to:

• put it in a View, it doesn't work
• use flex: 1 on the above mentioned View and on the QR Code

NOTE: I had to change the WebView in the node_modules since now it is a separate library.

I was trying to make a QR code marker like this pic below.

So I'm wondering how to make those 4 corners instead of a full border marker.

I was currently using react-native-qrcode-scanner.

The default marker is like this:

and here is the code that I have:

I'm getting this error with npm react-native-webview@9.0.1 when I try to generate a QR code with react-native-qrcode-generator

I'm using react-native with an expo managed workflow. And the thing is it works on iOS, and i only get the error on Android

I searched for a solution myself and I tried installing react-native-get-random-values but that also didn't work.

Any thoughts?

I want to build my app QRCODE GENERATOR in React Native Expo.

I work with QR code - module react-native-qrcode version 0.2.7, and I have this error.

Current code:

I am trying to run a 2 years old react-native project. When I run my project, it showing the error

Invariant Violation: WebView has been removed from React Native. It can now be installed and imported from 'react-native-webview' instead of 'react-native'. See https://github.com/react-native-community/react-native-webview

and

Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)

but I haven't installed or used any package named react-native-webview or webview and I have updated all gradle files and the dependencies in package.json to the current versions

my package.json

For a study project, I am currently developing a mobile application for reading QR Code in native React. Once a QR Code is scanned, I keep its id in memory in a history.

When I click on this id I want to open a page containing info about this QR code (retrieved by an API rest). But when I select an ID, the information obtained is that of the previous QR code.

I have created a button that updates the information, but I would like it to be directly the right one.

Thank you, I attach my code and the git of my project.

I try to render a qrcode using this library: react-native-qrcode-svg but I have this error:

Error while updating property 'fill' of a view managed by: RNSVGReact

I install the required package react-native-svg but the problem persist. I'm using the latest version of all packages.

This is the full code:
