I am making an app which loads the CSV and show the table on the screen but the load function is being called infinitely in the build state can anyone know how to fix it I wanted to call only once but my code called it many times.
Here is the console screenshot:
Here is the code:
import 'package:flutter/material.dart';
import 'package:csv/csv.dart';
import 'dart:async' show Future;
import 'package:flutter/services.dart' show rootBundle;
class TableLayout extends StatefulWidget {
@override
_TableLayoutState createState() => _TableLayoutState();
}
class _TableLayoutState extends State<TableLayout> {
List<List<dynamic>> data = [];
loadAsset() async {
final myData = await rootBundle.loadString("asset/dreamss.csv");
List<List<dynamic>> csvTable = CsvToListConverter().convert(myData);
return csvTable;
}
void load() async{
var newdata = await loadAsset();
setState(() {
data = newdata;
});
print("am i still being called called ");
}
@override
Widget build(BuildContext context) {
load();
return MaterialApp(
home: Scaffold(
appBar: AppBar(title: Text("Apps"),),
//floatingActionButton: FloatingActionButton( onPressed: load,child: Icon(Icons.refresh),),
body: ListView(
children: <Widget>[
Container(margin: EdgeInsets.only(top: 20.0),),
Table(
border: TableBorder.all(width: 1.0,color: Colors.black),
children: data.map((item){
return TableRow(
children: item.map((row){
return Text(row.toString(),style: TextStyle(fontSize: 20.0,fontWeight: FontWeight.w900),);
}).toList(),
);
}).toList(),
),
]),
));
}
}
Here is the solution.
@override
void initState() {
super.initState();
load(); // use it here
}
@override
Widget build(BuildContext context) {
return MaterialApp(...); // no need to call initState() here
}
