Snapshot has no data, Loading widget is shown forever

I followed the tutorials thoroughly, but loading widget is shown infinitely. I printed a message in output before if statement and it shows that snapshot has no data and so it goes to else statement and shows loading widget infinitely.

This issue has been faced with some more coders as can be [seen in comments for video 25](https://www.youtube.com/watch?v=PT3v28eyOqg&list=PL4cUxeGkcC9j--TKIdkb3ISfRbJeJYQwC&index=26&t=0s)
