I hope you're all having a swell day! I'm getting the following error whenever I search for a user in the search bar of my Messenger App in Flutter:

The following StateError was thrown building:

This is the piece of code that the error narrows down to:
Widget searchUsersList() {
return StreamBuilder(
stream: usersStream,
builder: (context, snapshot) {
return snapshot.hasData
? ListView.builder(
itemCount: snapshot.data.docs.length,
shrinkWrap: true,
itemBuilder: (context, index) {
DocumentSnapshot ds = snapshot.data.docs[index];
return searchListUserTile(
profileUrl: ds["imgUrl"],
name: ds["name"],
email: ds["email"],
username: ds["username"]);
},
)
: Center(
child: CircularProgressIndicator(),
);
},
);
}
I've double checked and the field names are correct, so I don't think it's that. So what is the issue here? If someone can help me fix it, it'd help me a lot! Thanks in advance.
CodePudding user response：
try to add this line
if(snapshot.connectionState==ConnectionState.done)
before the listview
CodePudding user response：
DocumentSnapshot does not directly contain the data. You can access data like ds.data()["imgUrl"] etc.
