Snapshot.data is null . The method[] was called on null - api

Question

I am new to flutter and I am trying to call api data in listview builder inside future builder. But I am getting null data in snapshot.
My code is below:
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import 'package:shared_preferences/shared_preferences.dart';
String token;
SharedPreferences sharedPreferences;
class ContinueW extends StatefulWidget {
#override
_ContinueWState createState() => _ContinueWState();
}
class _ContinueWState extends State<ContinueW> {
Future getTokenValue() async {
SharedPreferences espf = await SharedPreferences.getInstance();
token = espf.getString('tokenvalue');
return token;
}
Future createUser() async {
String url ='http://3.137.182.252:8000/continue-watching';
print('token');
Map<String, String> headers = {
'token': token,
};
await http.get(url, headers: headers).then((response){
print('Entered');
//print(response.body);
var jre= jsonDecode(response.body);
return jre;
});
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: FutureBuilder(
future: getTokenValue(),
builder: (BuildContext context,snapshot){
if(snapshot.hasData){
return cbuild();
} else{
return CircularProgressIndicator();
}
},
),
),
);
}
Widget cbuild(){
return new FutureBuilder(
future: createUser(),
builder: (BuildContext context,snapshot) {
if(snapshot.hasData) {
return ListView.builder(
itemBuilder: (context, index) {
return ListTile(
leading: CircleAvatar(
backgroundImage: snapshot.data['thumburl'] != null
? NetworkImage(snapshot.data['thumburl'])
: Container(),),
title: Text(snapshot.data[index]['name']),
subtitle: Text(snapshot.data[index]['description']),
);
},
);
}
else{
return CircularProgressIndicator();
}
}
);
}
}

Answer 1

ListTile(
leading: CircleAvatar(
backgroundImage: snapshot.data[index]['thumburl'] != null
? NetworkImage(snapshot.data[index]['thumburl'])
: Container(),),
title: Text(snapshot.data[index]['name']),
subtitle: Text(snapshot.data[index]['description']),
);
as according to details provided by you. you may be missing [index]with ['thumburl'],
if it's still not working then you need to provide JSON formated data
