I was using this guide to setup vscode before starting a react native project (tutorial link).
After installing flow-bin, reactive native library compnents are showing lots of errors. Although, the test project is running fine. Here is the screenshot for the same:
Can some help me for if I have missed something?
Thanks in advance!
by adding this in .flowconfig [options] section:
unsafe.enable_getters_and_setters=true
The error asked in this question will be fixed.

Currently, my project running on the 0.66.3 version I need to upgrade to react native version 0.70.6. So I have used to following command
npx react-native upgrade
After running this command showing some error I have attached a screenshot please refer.
I am also trying the manual way using react native helper but some files are not available in my project.
so anyone please tell me how I will upgrade my project version?
After Run npx react-native run-android my build was created successfully but 3 errors showing in the metro bundler. I have attached a screenshot of the metro bundler error.
you can specify a React Native version and pass it as an argument:
npx react-native upgrade 0.70.6
you can also refer this official documentation for this
& it will also helps you if you got any error.
https://reactnative.dev/docs/upgrading
I found by changing react-native - index.js and react-native/Libraries/Text - index.js
Follow this link for output:

Don't know whether it is the right way or not....
Since upgrading an application can break functionality in your app if you do not know what is needed to be changed. the upgrade is tells you to visit the pages to go through and see what has changed throughout the upgrading process.
Other as that I am just needing more information regarding to what is not working. Since upgrading is more as just running a command, its about reading the documentation and see what part is missing and what they replaced the files with. The missing files could be straight-out deprecated and not working with the new version.
As always check the debugger and read every message throughout and visit all links given and see the documentation regarding the upgrade differences, find out if there are any log files you could look at, and talk with people in your company / group of react-native about this.
"Some files are not available in my project"
This part might just be able to google and see if this is still supported or not in the version it could be phased out, or not supported in the version. that's where versioning comes in to play.
I am unsure what files and which libraries are deprecated based on your Opening Post, this needs more information, to help us, help you.
On starting application using react-native run-ios its showing error on simulator Unable to find module for EventDispatcher
Stop remote JS debugging and then reload the app
It will give you the appropriate error message, most likely missing some render on one of your components. That fixed it for me.
So this issue happened to me after I upgraded to RN 0.59.x.
I was getting this error when live reload was enabled or if i tried to refresh screen on iOS by pressing CMD+R.
Related issues:
Unable to find module for UIManager
Unable to find module for
DevLoadingView
Unable to find module for EventDispatcher
Here's how I solved it:
Edit your AppDelegate.m file and add the following code before the #end
#if RCT_DEV
- (BOOL)bridge:(RCTBridge *)bridge didNotFindModule:(NSString *)moduleName {
return YES;
}
#endif
This will fix the issue.
Link to the fix on github.
Related discussion on github.
Live reload and debug mode all should work without problems now.
This seems to be an issue when using the remote debugger with certain RN versions above 0.58. Using react-native-debugger should solve the issue as it supports RN versions above already.
It can be downloaded from the following link:
https://github.com/jhen0409/react-native-debugger/releases
I've started receiving this error after upgrading RN from v0.57.3 to v0.58.6.
Running packager with yarn start -reset-cache / react-native start --reset-cache fixed the issue for me.
What worked for me was simply stopping remote debugging as mentioned by #Hackman,
THEN killing the browser debugger, cleaning Xcode and rebuilding.
Couldn't tell you why, but the issue went away.
I'm using detox, what worked for me was switching the build command from
-configuration Debug
to
-configuration Release
It will no longer fetch from metro bundler and instead use the js bundle from the build. When I'm coding the tests, I build with debug since I'm fine with occasionally seeing the error, since I like the connivence of not having to constantly build and letting metro bundler do it for me.
I'm learning React Native and trying to add a component to an Expo Snack for testing. I can't even get the example app to work though.
Is it something different about how Snacks work vs. a desktop development environment? I've encountered that type of difference using JSFiddle, for example.
I straight copy-pasted the code from the Github repo into snack.expo.io and it gave me an error:
Device: (946:881) Unable to resolve module 'module://expo-font.js'
Evaluating module://expo-font.js
Evaluating module://react-native-numeric-input.js
Evaluating module://App.js
Loading module://App.js
I've gotten this error before, but I've never been able to figure out why. Is it an issue with the package, which was updated just 7 days ago, or something else? Please advise.
It may be due to missing of node modules in your project compared to the Github project. As the Stack.expo browser won't give us full freedom to install custom modules, I suggest you to download VS Code and open the Github project in it, then do "npm install" from cmd and "react-native run-android/ios".
I am building an app using Create-React-Native-App. As such, my testing and development is in Expo. I am looking for a solution to help with i18n, mostly translations and RTL. I found that ex-react-native-i18n works great, until I try ejecting to create the App, because it needs expo. (Which I don't need or want in the production App)
with react-native-i18n I get this error:
react-native-i18n module is not correctly linked
I tried react-native link and yarn link without success. The ReadMe page for react-native-i18n has extensive instructions for manual linking, but only for AFTER ejecting.
What am I missing here?
Is there a better solution that I'm missing?
Thanks.
I don't think it will be possible to get that module working before ejecting.
Have you tried this library?

I am a beginner in React Native and i have followed all the steps carefully as suggested in react-native Get-Started. Once the project is initiated and i try to run the same using run-android command, I am getting "java.net.UnknownhostException". To be particular, this issue is happening during gradle(https://services.gradle.org/distributions/gradle-2.2.1-all.zip) download.
I am on a corporate network and I have done the proxy setup as well in gradle-home/properties. I have tried downloading the gradle file manually and it works fine in my browser.
Any leads in fixing this issue is highly appreciated.
I think this link can solve your problem:
https://github.com/facebook/react-native/issues/2726
Edit gradle.properties in android sub-folder with the following details:
systemProp.http.proxyHost=proxyHost
systemProp.http.proxyPort=proxyPort
systemProp.https.proxyHost=proxyHost
systemProp.https.proxyPort=proxyPort
systemProp.http.proxyUser=YOUR_USERNAME
systemProp.http.proxyPassword=YOUR_PASSWORD
systemProp.https.proxyUser=YOUR_USERNAME
