                      traction.mvc Key Features

                      It's there when you need it, but doesn't get in your way. In designing this library, I intended it to solve a couple of issues with general Android development while trying to avoid many constraints other libraries put on the developer to use it. Activities and Fragments work as you would expect, and for the most part, you don't need to alter your approach much. The library introduces a few classes that are required for notifying updates to and from the UI, but doesn't lock you into using specific base classes (most core objects have interfaces and are designed to pass the functionality of the implementers to your own objects: for instance, if you don't want to use the base Activity or Fragment in the library, you can use your own and extend it with a helper class that takes care of the heavy lifting for you).

                      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}");
                                                                                          ^^^^

                      My Code:

                      import 'dart:convert';
                      import 'package:flutter/cupertino.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
                      }

                      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'));
