I am using react-native version 0.69 and I want to read a file stored in assets in my react native project.
using following syntax in App.js
import fs from 'react-native-fs';
I have installed 'react-native-fs' and followed all the links I could find on the internet but I am still getting below error while running the app.
ERROR TypeError: null is not an object (evaluating 'RNFSManager.RNFSFileTypeRegular')
ERROR Invariant Violation: "main" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current
project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called.
I tried to run react-native link react-nativs-fs but link support has been removed in react-native >= 60 as mentioned in official docs,
I am unable to get this to work, any help would be appreciated. I have seen similar issues on the stackoverflow but none has given the answer for react native >=0.60 versions
Also I am using expo to create the app.
my OS is Windows 10 64 bit.
react-native-fs is not supported with Expo but it is only supported by Pure React Native.
Expo has a package that offers filesystem support:
expo-file-system
I have already tried all of the answers in this previous thread and they have not worked
Unable to resolve "#react-native-community/masked-view
I have been unable to build my app in any capacity. Using expo ~42.0.0 to manage installations.
Unable to resolve module #react-native-masked-view/masked-view from
/node_modules/#react-navigation/elements/src/MaskedViewNative.tsx
Here is that file on their main branch
https://github.com/react-navigation/react-navigation/blob/main/packages/elements/src/MaskedViewNative.tsx
Just curious what this error means, expo documentation says react navigation uses #react-native-community/masked-view this error and code in the latest release says other wise
https://docs.expo.dev/versions/latest/sdk/masked-view/
Has anyone found a solution?
expo documentation says react navigation uses #react-native-community/masked-view
Expo documentation says React Navigation 5.x uses #react-native-community/masked-view. You're probably using React Navigation 6.x, not React Navigation 5.x. But it doesn't matter what Expo documentation says if you're getting an error because a specific package is missing and you already know which package it is.
You need to install #react-native-masked-view/masked-view:
expo install #react-native-masked-view/masked-view
This is my Code which is showing this error . Here I am trying to make a Drawer-navigation
This is the error showing , I am doing this in react-native.
It seems you might have missed some installation / setup steps for react-navigation.
Please check this section in the docs: https://reactnavigation.org/docs/getting-started#installing-dependencies-into-a-bare-react-native-project
If you have already installed the packages listed there (notably react-native-reanimated), perhaps you have not installed the native dependencies. This is important on iOS - run npx pod-install in your project root, and then build the app again (hot reload will not be enough).
I am trying to build simple app to creative native library and link with react native app.
I am facing issue like
Error : Unable to resolve module react-native-fingerprint from App.js: react-native-fingerprint could not be found within the project.
Note : 'react-native-fingerprint' which is been created and want to link with app.
I guess you're using react-native-fingerprint-scanner. Since library you mentioned doesn't exist.
In case if you using this library react-native-fingerprint-scanner.
Installation
npm install react-native-fingerprint-scanner --save
or
yarn add react-native-fingerprint-scanner
Link to Native Platforms
react-native link react-native-fingerprint-scanner
Even after this it is not working. Following this guide
I have a react native app built using Expo and everything was working fine until I had to npm install a package that broke everything. I've uninstalled the said package but the app doesn't seem to work any more. It shows the following invariant violation:
It shows an error Invariant Violation: ListView has been removed from React Native - however, I have not used ListView anywhere in my project. All my lists are through FlatList or VirtualisedList.
Additionally, I'm unable to deduce from the error info about the origin of this error. How do I fix this?
If you have the backup of the code please check the older version of React Native in package.json.
When you do npm install command your React Native version upgraded or may be some other packages.
So, you need to compare the packages with old package.json file. If you found that some packages are updated then you need to remove ^ e.g react-native: ^0.60.0 from package dependencies. This one is the only way to solve this problem.
