What im trying to do is filling a card with the necessary data it needs which is userImage and UserFirstname from my users collection and also data from my subcollection(carReviews)in my carInfo collection where i store the necessary review data: subcollection(carReviews)
StreamBuilder<QuerySnapshot>(
stream: FirebaseFirestore.instance
.collection('carInfo')
.doc(snapshot.data!.docs[index]
.get('CaradvId'))
.collection('carReviews')
.snapshots(),
builder: (context, snapshot5) {
return StreamBuilder<QuerySnapshot>(
stream: FirebaseFirestore.instance
.collection('users')
.where('uid',
isEqualTo: snapshot5
.data!.docs[index]
.get('reviewerId'))
.snapshots(),
builder: (context, snapshot6) {
return Container(
padding: EdgeInsets.symmetric(
horizontal: 5),
height: MediaQuery.of(context)
.size
.height *
0.225,
child: ListView.builder(
shrinkWrap: true,
scrollDirection:
Axis.horizontal,
itemCount: snapshot5
.data!.docs.length,
itemBuilder:
(BuildContext context,
int index) {
DateTime date = snapshot5
.data!.docs[index]
.get('reviewDate')
.toDate();
String dateString =
DateFormat(
'dd MMM yyyy')
.format(date);
return ConstrainedBox(
When i print snapshot5.data!.docs[index].get('reviewerId') i get the two ids who has reviewed which what is expected however the snapshot6.data!.docs.length is 1 which doesn't make any sense! I have tried using both snapshot6.data!.docs.length & snapshot5.data!.docs.length for the itemcount if i use snapshot6.data!.docs.length i get just one item in list with no errors and if i use snapshot5.data!.docs.length i get range error because it goes through all reviews which are just 2. Me using "hasdata" if statment wont change the output i have tried.
how it looks when i use snapshot5.data!.docs.length
how it looks when i use snapshot6.data!.docs.length
