In this parallel case, VasSonic can read and render partial data by WebKit or Blink kernel without spending too much time waiting for the end of data stream. VasSonic can cache html cleverly according to VasSonic Specification obeyed by client and server. VasSonic Specification specify template and data by inserting different comment anchor, templates are bigger parts of html which stay the same or changed rarely , in contradiction data, which is the smaller and constantly change part of html. According to this, VasSonic request less data by incremental updating templates and data, the websites are faster and feel more like native application.

QUESTION

Error: Property 'body' cannot be accessed on 'Response?' because it is potentially null

Asked 2022-Mar-29 at 00:29

so I'am trying to learn dart and flutter and everything went well so far. But now I'am stuck at an error which I cannot handle. I coded a function which is supposed to asynchronously return the actual BTC price from https://blockchain.info/ticker.

Only thing it returns is errors:

Error: Property 'body' cannot be accessed on 'Response?' because it is potentially null.
 - 'Response' is from 'package:http/src/response.dart' ('/D:/flutter/.pub-cache/hosted/pub.dartlang.org/http-0.13.4/lib/src/response.dart').
Try accessing using ?. instead.
          return Text("${BTCPrice.fromJson(jsonDecode(snapshot.data.body)).eur}");
                                                                    ^^^^
/D:/flutter/packages/flutter/lib/src/widgets/async.dart:242:12: Context: 'data' refers to a property so it couldn't be promoted.
See http://dart.dev/go/non-promo-property
  final T? data;
           ^

My Code:

import 'dart:convert';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;

Future<http.Response> fetchBTCPrice() async {
  final response = await http.get(Uri.https('blockhain.info', 'ticker'));
  return response;
}

Widget buildBTCPrice() {
  return FutureBuilder<http.Response>(
    future: fetchBTCPrice(),
    builder: (context, snapshot) {
      if (snapshot.hasData) {
        int? statusCode = snapshot.data?.statusCode;
        if (statusCode == 200) {
          return Text("${BTCPrice.fromJson(jsonDecode(snapshot.data.body)).eur}");
        }
        return Text('$statusCode');

      } else if (snapshot.hasError) {
        return Text('${snapshot.error}');
      }
      return CircularProgressIndicator();
    },
  );
}

class BTCPrice {
  final double eur;
  BTCPrice({required this.eur});

  factory BTCPrice.fromJson(Map<String, dynamic> json) {
    print(json);
    return BTCPrice(
      eur: json['eur']['15m']
    );
  }
}

Last things to mention: I'am running the application on a Android Emulator powerd by Android Studio; and please feel free to hand over any advice you have (in terms of code improvement), even if it is not fixing my issue.

To get rid of that error you need to use the bang operator to tell the compiler that snapshot.data won't be null.

if (statusCode == 200) {
  return Text(
 "${BTCPrice.fromJson(jsonDecode(snapshot.data!.body)).eur}"); // adding ! on data
}

Edit

The unrelated error you mentioned in your comment:

unexpected character (at character 1) <html><head><title>loading...</title></head><body><script type='text/javasc... ^

would be fixed by changing your GET request from this

final response = await http.get(Uri.https('blockhain.info', 'ticker'));

to this

final response = await http.get(Uri.parse('https://blockchain.info/ticker'));
