Herkese merhabalar ben Flutter öğrenmeye yeni başladım oradan buradan öğrendiklerimle bir ToDoList benzeri uygulama yapmaya çalışıyorum. Bu uygylamanın verilerini SqfLite kullanarak kaydetmek istiyorum fakat bir türlü başaramadım bana yardımcı olabilir misniz? Kodları aşağıya bırakıyorum.
main.dart:
`import ‘package:flutter/material.dart’;

runApp(const MyApp());
}

const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MaterialApp(
title: “Liste”,
debugShowCheckedModeBanner: false,
theme: ThemeData(

),
);
}
}

const AnaSayfa({Key? key}) : super(key: key);
@override
State<AnaSayfa> createState() => _AnaSayfaState();
}
class _AnaSayfaState extends State<AnaSayfa> {
@override
