google-cloud-firestore

问题 I've been using the firebase npm package to primarily interact with my Cloud Firestore + Authentication. I want to use the listDocuments method on a collection, but this doesn't seem to exist in when I have: import * as firebase from "firebase"; import "firebase/firestore"; const db = firebase.initializeApp(...).firestore(); db.collection("users").listDocuments() And it says that listDocuments() is not a function.

问题 I'm fetching coordinates from Firestore to fill my map with stores locations. The Google Map Marker needs a LatLng object (that takes two double as parameters) with the latitude and longitude of a point.

问题 I have looked all over the internet for how to fix this problem and I can't find a solution anywhere. I am using flutter with firestore to make an app. I want to make it so when the user logins into the app at the top shows their name (simple right).

问题 I created the database on cloud firestore, and the collection name is products. Now I want to retrieve all the resources in my collection. I have already created 12 products in my database.

问题 I'm actively using both of Firebase Realtime Database and Firestore. There is a case in which I need to check a document on Firestore to allow user to write on Firebase Realtime Database. Basically, I need to access user's document in the users collection on Firestore to allow user to create a post under the posts node on Firebase Realtime Database.
