title: How to automatically remove data from firestore after a specific time?
body: <p>I am developing an app in flutter where I have a stories section. Where users can upload stories ( Text / Images). What I want is to automatically delete the posts after one day.</p>
  <p>What I have achieved is to delete one day ago data by checking the timestamp of the post and a simple calculation and a remove call to delete it.</p>
  <p>But what I want to achieve is an automated process. Like data is automatically deleted after one day without checking for posts on random calls or time. Like I don't know if it's possible or not. But if someone has a solution it would be a great favour. Thakns</p>
