Return relative Firebase key from ngFor loop
I have data that I'm displaying in cards via an *ngFor loop. I'm having trouble returning the pushId for any individual record in the loop, on click. The goal is to return the pushId so I can load that item's data into its own "More Info" type page. What I have now returns only the last key in the array, not the one I clicked on. What am I missing?
code:
const snapshotToArray = snapshot => {
snapshot.forEach(childSnapshot => {
let item = childSnapshot.val();
item.key = childSnapshot.key;
console.log(childSnapshot.key);
})
}
this.ref = firebase.database().ref('users/' + user.uid + '/Posts');
this.ref.on('value', resp => {
this.infos = ;
this.infos = snapshotToArray(resp);
});
logKey(snapshot){
console.log(item.key);
}
<ion-card *ngFor="let info of infos" >
<ion-item detail lines="full" (click)="logKey()">
<div class="row">Key - {{info.key}}</div>
</ion-item>
</ion-card>
Any help would be appreciated. Thanks in advance..

on the click you need to pass key or index from where you can filter and get the results
– Just code
