requireActivity()

This method is used in Android development and is part of the androidx.fragment.app.Fragment class. It returns the Activity associated with the current Fragment.

The method is used to obtain a reference to the Activity in which the Fragment is currently running. This can be useful when you need to access resources or methods that are only available in the Activity.

For example, if you have a Fragment that needs to start a new Activity, you can use requireActivity() to obtain a reference to the current Activity and then use startActivity() to start the new Activity.

It's important to note that requireActivity() will throw an exception if the Fragment is not currently associated with an Activity. Therefore, it's recommended to use this method only after the Fragment has been attached to an Activity.
