Flutter for Beginners

Loading favors from Firestore

We use Firestore through the Firestore class from the cloud_firestore Dart library. In initState() function of the FavorsPageState, we add a call to watchFavorsCollection().

Collections are just a group of documents. In our app, we have a single collection called favors that store all of the favor documents from the app. A document is a record in a collection. They are commonly represented as JSON objects.

In watchFavorsCollection(), we start loading favors from Firebase as shown here:

 // part of favors_page.dart watchFavorsCollectionclass FavorsPageState extends State<FavorsPage> {  @override  void initState() {    super.initState();    ...    pendingAnswerFavors = List();    acceptedFavors = List(); completedFavors = List(); ...
