What is -r in the command line of npx jetify -r

I need to know the npx jetify -r what does it do?

I have set a script in package.json as

postinstall: npx jetify -r

Note: I am using the latest react-native (0.63)

But it have passed in all local builds. But it get failed in the cloud build of app circle.

I need to fix the below issues

How do I get new markings to show up when the user clicks a date? I'm sure I'm just missing some reference in documentation, but I would appreciate a pointer in the right direction.

I'm using the library react-native-calendars (https://github.com/wix/react-native-calendars) and their boilerplate code.

I want to add grid calendars to my React Native application, which should look like the Month view in Google Calendar (the left image). I have searched for the libraries and found React Native Calendar but as far as I can see, it can only give me the type of calendar that looks like the one on the right image. Is there any trick for React Native Calendar to make a grid calendar or is there any React Native library that supports making grid calendars?

I have a react native app that I'm trying to run on Android. However, every time I try to load Android Studio, it complains that I have a duplicate import.

When I check, I can only find one of the imports it complains about:

As title said I need to populate marked dates which im getting from API in Calendar component (i am using "react-native-calendars": "^1.403.0").

I'm trying to change the background of only one item in this agenda but with my code, when I click on an item, it changes the background color of all of them and not just the one I clicked : screen before clicking on item screen after clicking

The problem amounts to knowing just how to change the style of just one item in the agenda and not the style of all of them.

Here is my code :

I’m working on a project where I need to establish connection to printer with ESC-POS. Project is in react native and I currently test on Android emulator. I’ve found package that would do what I need (https://github.com/leesiongchan/react-native-esc-pos) but when I try to build an app it gives over 330 errors like:

Duplicate class org.junit.runners.model.MultipleFailureException found in modules escposjava-1.0-SNAPSHOT.jar (escposjava-1.0-SNAPSHOT.jar) and junit-4.12.jar (junit:junit:4.12)`

Those errors occur for task :app:mergeDebugJavaResource and the messages are:

My application was previously working fine, no build or runtime errors. Then I updated react-native-agora from ^2.9.1 to ^3.0.1-rc.4. Had a crash issue which was solved by

• pod install
• react-native start --reset-cache

My issue now is that the application is stuck on the splash screen and giving this error on iOS RN v0.61.5:

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

So far I've tried:

• adding index.ios.js file and adding entry point code
• removing and re-installing node_modules
• npm cache clean
• cleaning and re-building project in Xcode
• restarting computer
• killall -9 node
• react-native start --reset-cache
• deleting app in simulator and re-building/running
• deleted pods folder and pod install
• commenting out all react-native-agora code

I have not:

• run any form of react-native link on this agora package. I'm on v0.61.5

Also:

• because react-navigation is auto linked in .61.5, I believe there should be some kind of development pod in Xcode. I haven't looked when it was working, so nothing to compare to. but I dont see react-navigation in the dev pods, but i see its peer dependencies

my package.json:

I've got a CalendarPicker react-native-calendar-picker on a Modal, and it let's me select a date normally if I have nothing but a console.log(date) on it's onDateChange, but when it's function calls this.setState or this.props.changeDate, it doesn't change visually it's selection, but it logs well the new date.

Code
