I am trying to connect and print barcode sticker from Zebra ZT-411 printer, but can not find any working solution. Also I am new to mobile app development. Can someone help he here? I have tried https://github.com/anmoljain10 this package but its not compatible with my react native version which is v18.1.0. Is there any other packages I can use?
When I am using:-
npm i react-native-zebra-bluetooth-printer
This is the error showing:-

If I use:-
npm install --legacy-peer-deps react-native-zebra-bluetooth-printer
Then it installs the package without any problem but when I am trying to use any function from this package it says the function can not be found.
Here I am trying to use a function:-
import RNZebraBluetoothPrinter from 'react-native-zebra-bluetooth-printer';
RNZebraBluetoothPrinter.enableBluetooth().then((res) => {
//do something with res
})
And here is the error:-

While running npm -v react-native-gessture-handler it says: 8.15.0.
I have also tried using npm i react-native-splash-screen --force but it is not good for an expo application, and I am pretty sure that installing react-navigation-drawer with --force resulted the problem.
I am not really experienced with package managing so I do not really get the point of the error message. How can I install expo-splash-screen, and can somebody explain the error message?
It looks you have libraries that use different versions of react-native-gesture-handler. react-navigation-drawer is using and older react-native-gesture-handler version and this package is deprecated so you cannot update it to use a higher version of react-native-gesture-handler.
The best solution in my opinion is to change the package react-navigation-drawer to #react-navigation/drawer as it says in the documentation of the package.
The other alternative but at your own risk is to specify in the package.json a resolution with the react-native-gesture-handler you need in expo-splash-screen and every library that have as peer dependecy react-native-gesture-handler will use this specific version.
"resolutions": {
"react-native-gesture-handler": "x.x.x"
}
Let me know if it helps

You can take a look at this resource (the problem mainly deals with dependency conflicts):

I am unsure what am I doing wrong, or what steps I can take to remedy the issue. I've been trying to get my project up and running for a few days now, but I keep running into issues like this that have few solutions when I look them up.
That's because NPM installed the latest version of the package and some libraries uses an older version.
You should edit the package.json file of your project.
Go to the file on your react native project and find the line that has the definition of react-native -safe-area-context.
The line should look like this:
"react-native-safe-area-context": "^4.3.1"
And replace the version like this:
"react-native-safe-area-context": "3.1.9"
That worked for me.

vue-class-component still doesn't officially support Vue 3.
It has a Release Candidate (RC) version though, but it may not be ready for production.
See this comment: vue-class-component issue #406
To install it:
npm install vue-class-component#8.0.0-rc.1 vue-property-decorator#10.0.0-rc.3

As per this error (if i got it right), this requires a different version of react (17.0.1) which when installed solves the problem but this version of the react is not supported by expo.
Please provide a solution which will be compatible with expo.
After searching for a whole day, i thought to post it here. But just after posting, i got an answer in my mind.
Why not to clone it directly from the github instead of installing it with expo or npm.
Did the same thing and now working fine.
This issue was also raised on github but it had no solutions.
