Flutter Json Map<String, double> Listview - json

Question

Hello i want to show Json data on listview.builder. I can take a values from the Json but i cant show them on the listview.
This is the Json data.
{"success":true,"timestamp":1578778505,"base":"EUR","date":"2020-01-11","rates":{"AED":4.084603,"AFN":86.369994,"ALL":122.079994,"AMD":531.079988,"ANG":1.8526,"AOA":538.513234,
"ARS":66.270498,...}}
I want to show "rates" values on Listview.
There is a model for Json.(I used to model for quicktype.io)
Currency currencyFromJson(String str) => Currency.fromJson(json.decode(str));
String currencyToJson(Currency data) => json.encode(data.toJson());
class Currency {
bool success;
int timestamp;
String base;
DateTime date;
Map<String, double> rates;
Currency({
this.success,
this.timestamp,
this.base,
this.date,
this.rates,
});
factory Currency.fromJson(Map<String, dynamic> json) => Currency(
success: json["success"],
timestamp: json["timestamp"],
base: json["base"],
date: DateTime.parse(json["date"]),
rates: Map.from(json["rates"]).map((k, v) => MapEntry<String, double>(k, v.toDouble())),
);
Map<String, dynamic> toJson() => {
"success": success,
"timestamp": timestamp,
"base": base,
"date": "${date.year.toString().padLeft(4, '0')}-${date.month.toString().padLeft(2, '0')}-${date.day.toString().padLeft(2, '0')}",
"rates": Map.from(rates).map((k, v) => MapEntry<String, dynamic>(k, v)),
};
}
..
class _CurrencyListState extends State<CurrencyList> {
Map<String, double> rates;
String url= "xxxx";
Currency currency;
Future takeCurrency() async{
var response = await http.get(url);
var decodedJson = json.decode(response.body);
currency = Currency.fromJson(decodedJson);
rates = Map.from(decodedJson["rates"]).map((key, value) => MapEntry<String, double>(key, value));
}
void initState() {
// TODO: implement initState
super.initState();
takeCurrency();
}
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Currency"),),
body: FutureBuilder(future: takeCurrency() ,builder: (BuildContext context, AsyncSnapshot takenCurrency){
print('takenCurrency data is: ${currency.rates}');
return ListView.builder(itemCount: currency.rates.length ,itemBuilder: (context, index){
return Card(
child: ListTile(
title: Text(
I tried to print values on there but i couldnt find a way.
Thanks.

Answer 1

You are trying to print values but you can't? This is because your Future is not returning anything, so the FutureBuilder's snapshot is void.
(This is why it's important to give a type parameter to Future, such as Future<Currency>: the compiler would've caught you were not returning a Currency.)
Since you are using a StatefulWidget I assume you want to cache the result of your future, correct?
This is how:
class _CurrencyListState extends State<CurrencyList> {
Map<String, double> rates;
String url= "xxxx";
Future<Currency> future;
Future<Currency> takeCurrency() async{
var response = await http.get(url);
var decodedJson = json.decode(response.body);
return Currency.fromJson(decodedJson);
}
void initState() {
// TODO: implement initState
super.initState();
future = takeCurrency();
}
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Currency"),),
body: FutureBuilder(future: future ,builder: (BuildContext context, AsyncSnapshot snapshot){
if (snapshot.hasData) {
final currency = snapshot.data;
print('takenCurrency data is: ${currency.rates}');
return ListView.builder(itemCount: currency.rates.length ,itemBuilder: (context, index){
return Card(
child: ListTile(
title: Text(
When the future completes, now the snapshot will have data.

import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:json_parsing/models.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
List<Data> dataList = List();
bool _isLoading = false;
Rates rates = Rates();
Future<String> loadPersonFromAssets() async {
return await rootBundle.loadString('json/parse.json');
}
Future loadyourData() async {
setState(() {
_isLoading = true;
});
// this is the local json that i have loaded from the assets folder
// you can make the http call here and else everything later is the same.
String jsonString = await loadPersonFromAssets();
final dataRates = dataFromJson(jsonString);
dataList.add(dataRates);
setState(() {
_isLoading = false;
});
}
#override
void initState() {
// TODO: implement initState
super.initState();
loadyourData();
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: _isLoading
? CircularProgressIndicator()
: new ListView.builder(
itemCount: dataList.length,
itemBuilder: (BuildContext ctxt, int index) {
return Card(
child: Column(
children: <Widget>[
new Text(dataList[index].rates.tRY.toString()),
new Text(dataList[index].rates.uAH.toString()),
new Text(dataList[index].rates.wST.toString()),
new Text(dataList[index].rates.zMW.toString()),
],
),
);
}),
),
);
}
}
This is the main file where the data gets loaded and its been shown in the list view.
import 'dart:convert';
//// final data = dataFromJson(jsonString);
Data dataFromJson(String str) => Data.fromJson(json.decode(str));
String dataToJson(Data data) => json.encode(data.toJson());
class Data {
bool success;
int timestamp;
String base;
String date;
Rates rates;
Data({this.success, this.timestamp, this.base, this.date, this.rates});
Data.fromJson(Map<String, dynamic> json) {
success = json['success'];
timestamp = json['timestamp'];
base = json['base'];
date = json['date'];
rates = json['rates'] != null ? new Rates.fromJson(json['rates']) : null;
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['success'] = this.success;
data['timestamp'] = this.timestamp;
data['base'] = this.base;
data['date'] = this.date;
if (this.rates != null) {
data['rates'] = this.rates.toJson();
}
return data;
