إجابة Moataz Fouad سؤال في كيفية ايقاف CircularProgressIndicator() flutter كانت الإجابة المقبولة
مرحبا عزيزي, استخدم هذا الكود
class MainListView extends StatefulWidget {
MainListViewState createState() => MainListViewState();
}
class MainListViewState extends State {
final String apiURL = 'http://====================/getStudentInfo.php';
Future<List<Studentdata>> fetchStudents() async {
var response = await http.get(apiURL);
if (response.statusCode == 200) {
final items = json.decode(response.body).cast<Map<String, dynamic>>();
List<Studentdata> studentList = items.map<Studentdata>((json) {
return Studentdata.fromJson(json);
}).toList();
return studentList;
}
else {
throw Exception('Failed to load data from Server.');
}
}
@override
Widget build(BuildContext context) {
return FutureBuilder<List<Studentdata>>(
future: fetchStudents(),
builder: (context, snapshot) {
if (!snapshot.hasData)
return Center(
child: CircularProgressIndicator()
);
///Alert there is a modification
if(snapshot.data.length == 0){
return Text('Sorry:( there is no data');
}
return ListView(
children: snapshot.data
.map((data) => Column(children: <Widget>[
GestureDetector(
child: Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Padding(
padding: EdgeInsets.fromLTRB(20, 5, 0, 5),
child: Text(data.studentName,
style: TextStyle(fontSize: 21),
textAlign: TextAlign.left))
]),),
Divider(color: Colors.black),
],))
.toList(),
);
},
);
}
}
