I checked the documentation, and the BottomSheet provides three events: Show, Dismissed, and Showing. Currently, I am using these events in the ViewModel to manage the page opacity. However, if these events are handled in the code-behind file, it eliminates the need to manually set the page opacity every time. I’ve tested this approach, and it works perfectly.

For those who prefer not to use the code-behind file, an even better solution is to create a custom BottomSheet base class. This way, the event handling can be centralized, and individual BottomSheets can simply inherit the event properties from the base class. I’ve tested this approach as well, and it works seamlessly.
