What are the main differences between using BottomSheetDialog and BottomSheetDialogFragment when implementing a bottom sheet?

The main differences between BottomSheetDialog and BottomSheetDialogFragment in Android are related to lifecycle and UI management:

• BottomSheetDialog is a class that represents a dialog with a bottom sheet. It is not a fragment, so its lifecycle is not tied to the Activity or Fragment lifecycle. It provides a simplified way to show a bottom sheet but requires manual state management, for example, the dialog may disappear on screen rotation.

• BottomSheetDialogFragment is a fragment that displays a BottomSheetDialog. It integrates with the fragment system, allowing automatic management of lifecycle, state, and restoration after configuration changes (such as screen rotation). This is a more flexible and recommended way to implement a bottom sheet.

In summary:

• Use BottomSheetDialogFragment if you need lifecycle support, state preservation, and navigation integration.
• Use BottomSheetDialog for simple cases where state management and lifecycle handling are not required.
