I am trying to get list of data from my firebase database to display on the activity, but I am getting the following error the getter snapshot is not defined for the type object, I try to add a null theck but it still give me the red line I comment aside the line which give the error.
Widget loadPeople(DatabaseReference _peopleRef) {
return StreamBuilder(
stream: _peopleRef.onValue,
builder: (context,snapshot){
if(snapshot.hasData){
List<UserModel> userModels =<UserModel>[];
Map<dynamic,dynamic> values = snapshot.data!.snapshot.value; //error come from this line on the second snapshot it gives the red line
values.forEach((key, value) {
if(key != FirebaseAuth.FirebaseAuth.instance.currentUser.uid){
var userModel = UserModel.fromJson(json.decode(json.encode(value)));
userModel.uid = key;
userModels.add(userModel);
}
});
return ListView.builder(
itemCount: userModels.length,
itemBuilder: (context , index){
return GestureDetector(
onTap: () {},
child: Column(
children: [
ListTile(
leading: CircleAvatar(backgroundColor: Colors.primaries[
Random().nextInt(Colors.primaries.length)
],
child: Text('${userModels[index].firstName.substring(0,1)}',
style: TextStyle(color: Colors.white) ),),
title: Text('${userModels[index].firstName} ${userModels[index].lastName}',
style: TextStyle(color: Colors.white),),
subtitle: Text('${userModels[index].phone} ',
style: TextStyle(color: Colors.white),),
),
Divider(thickness: 2,)
],
),
);
});
}
else return Center (child: CircularProgressIndicator(),);
});
