Answer 1

There are many ways to communicate between fragments. The best way is to use fragment managers.

In fragment 3, initialize the listener.

setFragmentResultListener("requestKey") { key, bundle ->
    // Any type can be passed via to the bundle
    val result = bundle.getString("data")
    // Do something with the result...
}

From fragment 1, you can pass the data with the help of request keys and bundle.

setFragmentResult("requestKey", Bundle())

Make sure the fragment version is up to date.
