Я получаю данные из коллекции firebase на страницу, но страница не возвращает никаких данных. Ошибок нет, но я не получаю никаких данных. Страница застревает на круговом индикаторе выполнения (я назначил циклический прогресс оператору if, когда нет данных).
Вот код (примечание: shopRef объявлен на домашней странице):
class Live extends StatefulWidget {
@override
_LiveState createState() => _LiveState();
}
class _LiveState extends State<Live> {
getProducts()async {
QuerySnapshot snapshot = await shopRef
.orderBy('timestamp', descending: true).getDocuments();
List<ShopItem> shopItems = [];
snapshot.documents.forEach((doc) {
shopItems.add(ShopItem.fromDocument(doc));
});
return shopItems;
}
@override
Widget build(BuildContext context) {
return Scaffold(appBar: AppBar(backgroundColor: kPrimaryColor,
title: Text( 'FASHOWtv',
style: TextStyle(
fontFamily :"MajorMonoDisplay",
fontSize: 35.0 ,
