Hi Please follow below link for your solutions.

https://www.journaldev.com/14207/android-passing-data-between-fragments

You can also use Navigation Graph for Fragment Transaction and directly send any kind of data in bundle to send it like below.

var nameBundle = Bundle()
nameBundle.putString("youKey", edtName.text.toString())
it.findNavController().navigate(R.id.tofragmentName, nameBundle)

It is not recommended that two Fragments should communicate directly. Check out the documentation and examples here. https://developer.android.com/training/basics/fragments/communicating

I would recommend a common ViewModel and observe the changes there.

You can use SafeArgs that are part of Navigation component on Jetpack. Here you have nice tutorial made by Google.
