How to create a custom sheet like ShareSheet

  android, user-interface

I want to create a sheet just like Sharesheet in android. I want it to open up from the top when clicked on a button. Something like this (You don’t need a username or password while logging in while going through that link, it’s the example website provided in flutter documentation), when clicked on the shopping icon.

I did some research but could not find anything useful. How can I make it like that? please do help me if you have any idea how it’s done.
