I'm getting a blank screen instead of firestore data - flutter

Question

my main code:
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:day_event_viewer/services/firestore.dart';
import 'package:flutter/material.dart';
class TodayEventScreen extends StatefulWidget {
#override
_TodayEventScreenState createState() => _TodayEventScreenState();
}
class _TodayEventScreenState extends State<TodayEventScreen> {
#override
Widget build(BuildContext context) {
return SafeArea(
child: StreamBuilder(
stream: getUserDatas(),
builder:
(BuildContext context, AsyncSnapshot<QuerySnapshot> snapshot) {
if (!snapshot.hasData) {
return const Text('loading data');
} else if (snapshot.hasData) {
return ListView(
children: snapshot.data!.docs.map((DocumentSnapshot document) {
Map<String, dynamic> data =
document.data()! as Map<String, dynamic>;
return ListTile(
title: Text(data['name']),
// subtitle: Text(data['company']),
);
}).toList(),
);
}
return const Text('somethng\'s wrong');
}),
);
}
}
the stream getUserDatas() mentioned above:
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:day_event_viewer/screens/add_screen.dart';
Stream<QuerySnapshot> getUserDatas() async* {
final uid = await getUid();
yield* FirebaseFirestore.instance
.collection('usersdatas')
.doc(uid)
.collection('profile')
.where('date', isEqualTo: DateTime.now().day)
.snapshots();
}
when I comment the code ".where('date', isEqualTo: DateTime.now().day)" 'above 4 lines' it's working fine so i think maybe my querying is the problem but i don't know how to fix it.

Answer 1

try this
title: Text(document.get('name')),

Answer 2

you should put else keyword before this line.
return const Text('somethng\'s wrong');
