db.ref('UsersList/').child('name you want to use').set({
    email:this.state.email,
    fname: this.state.lastname,
    lname: this.state.firstname,
}).then((data)=>{
    //success callback
    alert('success'+data);
}).catch((error)=>{
    //error callback
    alert('failed'+error);
  })

something like this worked for me and I was able to store based on special usernames I needed.

Every time you call push() Firebase generates a reference to a new, unique location in the database. So ref.push() creates a new, unique location under ref.

If you want to simply set the name under the contact's ID, change ref.push(contact.name); to:

ref.set(contact.name);
