I tried geting data from firebase and display it using streamBuilder but I get this error, how do I solve it.
body:
StreamBuilder<QuerySnapshot>(
stream: firestore.collection('paymnet data').snapshots(),
builder: (context, snapshot) {
return ListView(
children: [
snapshot.data!.docs.map((DocumentSnapshot document){
Map<String,dynamic> data = document.data()! as Map<String, dynamic>;
return ListTile(
title: Text(data['amount']),
subtitle: Text(data['paid date']),
);
}).toList();
],
);
})
CodePudding user response:
Just remove []
from listView children
body:
StreamBuilder<QuerySnapshot>(
stream: firestore.collection('paymnet data').snapshots(),
builder: (context, snapshot) {
return snapshot.hasData?ListView(
children:
snapshot.data!.docs.map((DocumentSnapshot document){
Map<String,dynamic> data = document.data()! as Map<String, dynamic>;
return ListTile(
title: Text(data['amount']),
subtitle: Text(data['paid date']),
);
}).toList();
):Container();// or add circular progress bar
})
