I'm new to react native and I'm working on firebase push notification. I'm getting the notification, but the problem is I'm not able to fetch data and display it in flatlist. Notification are shown perfectly. But the problem is why I can't fetch data.
componentWillMount() {
const firebase = require("firebase");
if (!firebase.apps.length) {
firebase.initializeApp(db);
}
this.fetchEventsList()
}
// Fetch events list
fetchEventsList = () => {
Preference.set('userPhoneCheck', '+917508060520');
let phone = Preference.get('userPhoneCheck');
firebase.database().ref('/users').child(phone).child('/events').once('value').then((snapshot) => {
let data = snapshot.val();
let items = Object.values(data);
this.setState({
userEventsList: items
});
// this.deleteOldEvents();
this.initAllEventList();
}).then((data) => {}).catch((error) => {
//error callback
console.log('error ', error)
})
}
//fetch the friends list according to group name
initAllEventList = () => {
//let groupName='G1';
let eventId = '';
let userEventsList = [...this.state.userEventsList];
for (var i = 0; i < userEventsList.length; i++) {
eventId = userEventsList[i].eventId;
ToastAndroid.show("eventId>" + eventId, ToastAndroid.SHORT);
if (eventId != '') {
this.fetchFriendsList(eventId);
}
}
}
//app users remove that not in contacts
fetchFriendsList = (eventId) => {
let allEventsList = [...this.state.allEventsList];
firebase.database().ref('/events').child(eventId).once('value').then((snapshot) => {
let data = snapshot.val();
let items = Object.values(data);
allEventsList.push(items);
this.setState({
allEventsList: allEventsList
});
ToastAndroid.show("kk>" + allEventsList.length, ToastAndroid.SHORT);
}).then((data) => {
}).catch((error) => {
//error callback
console.log('error ', error)
})
}

When you run this code, which precise piece of it doesn't do what you expect it to do?
