The getter 'docs' isn't defined for the type 'Object'. Try importing the library that defines 'docs', correcting the name to the name of an existing getter, or defining a getter or field named 'docs'
Stream collectionStream = FirebaseFirestore.instance.collection('users').snapshots();
Stream documentStream = FirebaseFirestore.instance.collection('users').doc('ABC123').snapshots();
class UserInformation extends StatefulWidget {
@override
_UserInformationState createState() => _UserInformationState();
}
class _UserInformationState extends State<UserInformation> {
final Stream<QuerySnapshot> _usersStream = FirebaseFirestore.instance.collection('users').snapshots();
@override
Widget build(BuildContext context) {
return StreamBuilder<QuerySnapshot>(
stream: _usersStream,
builder: (BuildContext context, AsyncSnapshot<QuerySnapshot> snapshot) {
if (snapshot.hasError) {
return Text('Something went wrong');
}
if (snapshot.connectionState == ConnectionState.waiting) {
return Text("Loading");
}
return new ListView(
children: snapshot.data.docs.map((DocumentSnapshot document) {
Map<String, dynamic> data = document.data() as Map<String, dynamic>;
return new ListTile(
title: new Text(data['full_name']),
subtitle: new Text(data['company']),
);
}).toList(),
);
},
);
}
