How to insert data in firebase using expo..? - react-native

Question

I've an issue, actually I want to insert data into firebase using expo from different screen(I'm using google auth in another screen and after completing it I'm going to main screen), it's working also but it is not saving data in which table I want it to store(after google auth, I'm saving data into firebase in 'users')..
// I'm using this code to insert data in first place (while login)
// and I'm also using isUserNew() method and it's working really fine..
onSignIn = googleUser => {
console.log('Google Auth Response', googleUser);
// We need to register an Observer on Firebase Auth to make sure auth is initialized.
var unsubscribe = firebase.auth().onAuthStateChanged(function(firebaseUser) {
unsubscribe();
// Check if we are already signed-in Firebase with the correct user.
if (!this.isUserEqual(googleUser, firebaseUser)) {
// Build Firebase credential with the Google ID token.
var credential = firebase.auth.GoogleAuthProvider.credential(
googleUser.idToken,
googleUser.accessToken
);
// Sign in with credential from the Google user.
firebase.auth().signInAndRetrieveDataWithCredential(credential).then(function(result) {
console.log('user signed in');
if(result.additionalUserInfo.isNewUser){
firebase.database().ref('/users/' + result.user.uid).set({
gmail: result.user.email,
profile_picture: result.additionalUserInfo.profile.picture,
locale: result.additionalUserInfo.profile.locale,
first_name: result.additionalUserInfo.profile.given_name,
last_name: result.additionalUserInfo.profile.family_name,
created_at: Date.now()
}).then(function (snapshot){
// console.log('Snapshot', snapshot);
});
}else{
firebase.database().ref('/users/' + result.user.uid).update({
last_logged_in: Date.now()
});
}
}).catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// The email of the user's account used.
var email = error.email;
// The firebase.auth.AuthCredential type that was used.
var credential = error.credential;
// ...
});
} else {
console.log('User already signed-in Firebase.');
}
}.bind(this));
};
// This code is also showing an error that I can't call setState from an //unmounted component.
// :- this function as well update() in firebase is in another screen or page.
async componentDidMount() {
try {
let {status} = await Permissions.getAsync(Permissions.LOCATION);
if(status !== 'granted'){
const {status} = await Permissions.askAsync(Permissions.LOCATION);
}else{
const watchId = navigator.geolocation.watchPosition(
({ coords : {latitude, longitude} }) => this.setState({latitude, longitude}, () => console.log('State:', this.state)),
(error) => this.setState({ error: error.message }),
{ enableHighAccuracy: true, timeout: 0, maximumAge: 1000, distanceFilter: 1},
);
await AsyncStorage.setItem('LiveFeedId', JSON.stringify(watchId));
}
}
catch(err) {
console.error(error);
}
};
/* when I'm using this code it's saving the data but not in 'users' table in firebase */
firebase.database().ref('users/').update({
latitude: latitude,
longitude: longitude,
});
Can anyone please help me out here, I'm really new to react native..
And I want to update my latitude and longitude from another screen to firebase where I've saved my users details, ex:- 'firebase.database().ref('/users/' + result.user.uid)'..
Thanks
