Hi Siva,
It doesn't appear that there are any events that fire when the SettingsFlyout is shown or hidden.
There is an event that fires when the back button is clicked:

If my reply answers your question, please mark this post as answered.
NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined
objects and unknown namespaces.
