hello... try this
child: Padding(
padding: const EdgeInsets.all(1.0),
child: RaisedButton(
onPressed: () async {
var result = await CallLog.query();
setState(() {
_callLogEntries = result;
});
},
child: Text("Get All"),
),
),
),
_callLogEntries.isEmpty
? Container()
: createPadding(),
..........
Widget createPadding(){
var children = <Widget>[];
_callLogEntries.forEach((entry){
children.add(
Column(
children: <Widget>[
Divider(),
Text('NUMBER : ${entry.formattedNumber}', style: mono),
Text('NAME : ${entry.name}', style: mono),

I did this and works
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
Iterable<CallLogEntry> _callLogEntries = [];
class CallLogEntry{
int formattedNumber;
String name;
CallLogEntry({this.formattedNumber, this.name});
}
class CallLog{
static Future<Iterable<CallLogEntry>> query() async {
var call1 = CallLogEntry(formattedNumber:1, name:'Name 1');
var call2 = CallLogEntry(formattedNumber:2, name:'Name 2');
Iterable<CallLogEntry> _callLogEntries = [call1, call2];
await Future.delayed(Duration(seconds: 1));
return _callLogEntries;
}
}
