I am trying the new arch of react native. I have enabled it in my gradle.properties file. This error is for android only and I have not tried iOS yet.
I am following the exact sample of Calculator mentioned over here.
I get an error saying
error: Error: While resolving module `rtn-calculator/js/NativeCalculator.js`, the Haste package `rtn-calculator` was found. However the module `js/NativeCalculator.js` could not be found within the package.

Below is sample code
