title: How to search for user data and retrieve them from firebase with flutter?
body: <p>I am trying to retrieve user data that I stored on firebase database and compare it to an inputed text &quot;trying to login but with another way ;)&quot; but when I search for examples I can't quite understand their methods of retrieving data they don't retrieve specific data but the collection, so any ideas?
