How does react-native-device-info Package work?

Question

I have implemented react-native-device-info package in my React Native App & My University professor is now asking me to describe how does this package work in order to get the required info. what callbacks, etc are used or how does it communicate with the system to bring that info to us.

I have searched through the internet but can't seem to find the answer.

So, I want to know & learn how react-native packages work & more specifically the package react-native-device-info works?

Answer 1

I went on to look at the source code for the package, and you will see that there are ios and android files in the root, and if you take a closer look you will see platform native code that is passing messages via the RN Bridge module. I am no expert on the field, but this should be the general explanation.
