React native and Firebase real time database querying gives null

I'm using firebase real time database with react native. Here I'm trying to login the user based on email address. 

firebase.database().ref('Users')
      .startAt(email)
      .endAt(email)
      .once('value', function (snap) {
        console.log(snap)
        console.log('accounts matching email address', snap.val())
      });

I have number of documents inside the Users collection. I'm trying to fetch the document which contains the email address I'm passing inside email variable. But in the console I'm getting the value as null.

accounts matching email address, null

I'm giving proper email address in the variable. Any ideas?

You should use equalTo() to query according to the email address:

firebase.database().ref('Users')
      .orderByChild("email")
      .equalTo(email)
      .once('value', function (snap) {
        console.log(snap)
        console.log('accounts matching email address', snap.val())
      });

Assuming you have the following db:

Users
  randomId
       email : email_here
