Join listview with firebase

I have approximately one million names stored in Firebase. I want to display these names in Listview so that I can search for them and choose the desired names.
I tried to connect ListView with Firebase and it did not work. I would be grateful to anyone who can guide me to a solution.

You probably do not want to do this.

What you should do is a direct search on Firebase.

Show the structure of your data on the firebase console...

how can you show a million item on screen same time? and how to browse them?
