And this is where i call api :
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import '../models/apis/hisselist.dart';
class Hisseler extends StatefulWidget {
const Hisseler({Key? key}) : super(key: key);
#override
State<Hisseler> createState() => _HisselerState();
}
class _HisselerState extends State<Hisseler> {
final scaffoldKey = GlobalKey<ScaffoldState>();
final url = Uri.parse('https://api.collectapi.com/economy/hisseSenedi');
var counter;
Hisselist? hisseResult;
Future callHisse() async {
try{
Map<String, String> requestHeaders = {
'Content-Type': 'application/json',
'Authorization': 'apikey 4xxxxP'
};
final response = await http.get(url,headers:requestHeaders);
if(response.statusCode == 200){
var result = hisselistFromJson(response.body);
if(mounted);
setState(() {
counter = result.result.length;
result.result.sort((a, b) => (a.text ?? "").compareTo(b.text ?? ""));
hisseResult = result;
});
return result;
} else {
print(response.statusCode);
}
} catch(e) {
print(e.toString());
}
}
#override
void initState() {
// TODO: implement initState
super.initState();
callHisse();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
centerTitle: false,
automaticallyImplyLeading: false,
title: Text(
'Hisseler'
),
),
body: Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: counter != null ?
ListView.separated(
itemCount: counter,
separatorBuilder: (context, index) {
return Divider(color: Colors.grey[400]);
},
itemBuilder: (context, index){
return Card(
child: ListTile(
contentPadding: EdgeInsets.all(10),
title: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(hisseResult?.result[index].code??"", style: TextStyle(color: Colors.black, fontSize: 16, fontWeight: FontWeight.w500)),
Text(hisseResult?.result[index].text??"",style: TextStyle(color: Colors.grey[500], fontSize: 14))
],
),
trailing: Column(
children: <Widget>[
Text(hisseResult?.result[index].lastpricestr??"", style: TextStyle(color: Colors.black, fontSize: 16, fontWeight: FontWeight.w500)),
Container(
alignment: Alignment.center,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(5),
color: Colors.red
),
width: 75,
height: 25,
child: Text(hisseResult?.result[index].rate.toString()??"",style: TextStyle(color: Colors.white))
)
],
),
),);
}) : Center(child: CircularProgressIndicator(
)),
),
),
);
}
}
This is the result i get:
as you see here, code response start with "https:" i don't want to show this "https:" part from response. How i can fix this?
Thanks for your help

Answer 1

seems the "https:" comes emberded in your API data, therefore we need to replace that string from the variable code.
Replace the Text code with this:
Text((hisseResult?.result[index].code ?? "")
.replaceAll("https:", ""),
style: TextStyle(
color: Colors.black,
fontSize: 16,
fontWeight: FontWeight.w500))

Answer 2

Try this:
hisseResult?.result[index].code?.substring(5)
null safety fix also added
subString changed into substring
