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.

Answered 2022-Mar-29 at 00:29

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'));

QUESTION

Flutter: How do I disable scrolling for a GridView widget, but have scrolling enabled for the page as a whole?

Asked 2022-Feb-06 at 09:48

I'm building an app where I have a page which gives information about a specific trading card. I want the page to be scrollable, but I also want to have a grid on the page, with each grid cell showing one data point. I made the grid using GridView.count().

My problem is that instead of have a page which I can scroll through, the top half of the page stays static, while the grid is scrollable. How do I make the grid static, while the rest of the page scrollable? I intend to have more data below this grid as well, and I want to user to be able to scroll to see all of it, with the grid being a static component of the page.

Here's my code:

import 'package:flutter/material.dart';
import 'package:pokehub/size_config.dart';
import 'package:pokemon_tcg/pokemon_tcg.dart';

class CardInfo extends StatefulWidget {
  PokemonCard card;

  CardInfo({required this.card});

  @override
  _CardInfoState createState() => _CardInfoState();
}

class _CardInfoState extends State<CardInfo> {
  @override
  Widget build(BuildContext context) {

You can provide physics: NeverScrollableScrollPhysics() on GridView to disable scroll effect. If you want scrollable as secondary widget use primary: false,

To have Full Page scrollable, you can use body:SingleChildScrollView(..) or better using body:CustomScrollView(..)

QUESTION

Flutter: Circular Color Picker (Package: flutter_colorpicker)

Asked 2021-Dec-19 at 00:02

I used this flutter package to implement a color picker in my app. My Widget looks something like this:

     ColorPicker(
              pickerColor: model.color,
              onColorChanged: (color) {
               ...
              },
              showLabel: false,
              pickerAreaHeightPercent: 0.4,
            )

This works fine and looks like this in the UI:

Now I wondered how I could implement a classical circular color picker. I did not find an example in the official documentation but there is a screenshot in the package description that shows just this:

Does anyone know how to implement this using the same package or can hint me to an example.

please check out this and you need to palette type as paletteType: PaletteType.hueWheel,. use the same package as used.

import 'package:flutter/material.dart';
import 'package:flutter_colorpicker/flutter_colorpicker.dart';


void main() => runApp(const MaterialApp(home: MyApp()));

class MyApp extends StatefulWidget {
  const MyApp({Key key}) : super(key: key);

  @override
  State<StatefulWidget> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  bool lightTheme = true;
  Color currentColor = Colors.amber;
  List<Color> currentColors = [Colors.yellow, Colors.green];
  List<Color> colorHistory = [];

  void changeColor(Color color) => setState(() => currentColor = color);
  void changeColors(List<Color> colors) => setState(() => currentColors = colors);

  @override
  Widget build(BuildContext context) {
    final foregroundColor = useWhiteForeground(currentColor) ? Colors.white : Colors.black;
    return AnimatedTheme(
      data: lightTheme ? ThemeData.light() : ThemeData.dark(),
      child: Builder(builder: (context) {
        return Scaffold(
          appBar: AppBar(
            title: const Text('Flutter Color Picker Example'),
            backgroundColor: currentColor,
            foregroundColor: foregroundColor,

          ),
          body: Container(
            child: InkWell(
              onTap: (){
                showColorPicker();
              },
              child: Center(child: Text("Color Picker")),
            ),
          ),
        );
      }),
    );
  }

  void showColorPicker() {
    showDialog(context: context, builder: (BuildContext context){
      return AlertDialog(
        title: Text("Pick a color"),
        content: SingleChildScrollView(
          child: ColorPicker(
            pickerColor: Color(0xff443a49),
            paletteType: PaletteType.hueWheel,
          ),
      ),
      );
    });
  }
}
