here I’m trying to get the top 10 names only from my firebase firestore,
and I searched on how I do it with the listview that I have, but I get to nowhere.
so I thought about getting the id of my documents instead.
In my firestore I gave the top 10 documents IDs from 1 to 10, now I’m stuck and I have no idea how to do it. please help.
static int id = 1;
StreamBuilder<QuerySnapshot>(
stream: fireStore.collection(path).snapshots(),
builder: (context, snapshot) {
if(!snapshot.hasData){
return Center(
child: CircularProgressIndicator(
backgroundColor: Colors.blueAccent,
),
);
}
List<InfoBox> ancients = [];
try {
final collection = snapshot.data!.docs;
for (var collect in collection) {
final name = collect['Name'];
final image = collect['Image'];
final collectionWidget = InfoBox(
ancientName: name,
ancientImage: image
);
ancients.add(collectionWidget);
}
}catch(e){
print('problems in stream builder \n error : $e');
}
return Expanded(
child:ListView(
children: ancients,
)
);
},
);
>Solution :
You are probably searching for limit() function. According to the documentation:
To limit the number of documents returned from a query, use the limit method on a collection reference
You can implement it like this:
fireStore.collection(path).limit(10).snapshots();
