Exception: FormatException: Unexpected character (at character 1) - json

Question

I'm new to flutter and learning through a tutorial about Flutter So I was following the same codes and already tried rewriting almost everything but when I started to run the app and i got that above error.
ERROR:flutter/lib/ui/ui_dart_state.cc(157)
Exception: FormatException: Unexpected character (at character 1)
E/flutter (14218):
My codes:
import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart';
class Loading extends StatefulWidget {
#override
_LoadingState createState() => _LoadingState();
}
class _LoadingState extends State<Loading> {
void getTime() async {
Response response= await get('http://worldtimeapi.org/timezone/Europe/London');
Map data=jsonDecode(response.body);
print(data);
}
#override
void initState() {
// TODO: implement initState
super.initState();
getTime();
}
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey,
appBar: AppBar(
backgroundColor: Colors.blue[800],
title: Text('here is loading'),
),
body: Text("choose location screen"),
);
}
}

I think you mean this link: https://worldtimeapi.org/api/timezone/Europe/London.
Not this one:
Response response= await get('http://worldtimeapi.org/timezone/Europe/London');
The link I gave you above gives you a JSON response in which you decode in your app. You were linking to an actual webpage that doesn't give you a JSON response, that's why you got that error. I have also made it HTTPS so it's more secure in your app.
