filtering data from firebase-realtime-database

Question

I am trying to get data from firebase with value of user's username. I've tried 2 different method a week ago, but now I'm back at it, I noticed I've deleted it.

Here inside home.ts where I subscribe the data

this.database.list<EventModels>('event-list').valueChanges().subscribe((eventData) => { 

}, (err)=>{
 console.log("Error while retrieving event details : ", err);
}); 

this.eventListRef$ = this.database.list<EventModels>('event-list');
this.eventList$ = this.eventListRef$.snapshotChanges()
.pipe(
  map(changes => 
    changes.map(c => ({ id: c.payload.key, ...c.payload.val() }))
  )
);

The data I want to filter is equal to creator

Since I set creator to user's email, I want to list all event that was created by the user only, by using == firebase.auth().currentUser.email and all the one that I've tried failed.

From the AngularFire documentation on querying lists:

db.list('/items', ref => ref.orderByChild('size').equalTo('large'))

So it looks like yours should be something like:

this.eventListRef$ = this.database.list<EventModels>('event-list', 
  ref => firebase.database().ref("event-list").orderByChild("email").equalTo(firebase.auth().currentUser.email));
