This part of the project is for the feedback page.
I am building this part in our project I manage to connect it to Firestore but the validation is not working I read the flutter docs to no avail I did not manage to make it work. Do I really need a global key? Is my code to connect to Firestore wrong?
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';
class SimpleDialog extends StatelessWidget {
// ignore: prefer_typing_uninitialized_variables
final title;
const SimpleDialog(this.title, {super.key});
@override
Widget build(BuildContext context) {
return AlertDialog(
title: const Text('Alert'),
content: Text(title),
actions: [
TextButton(
onPressed: () {
Navigator.of(context).pop();
},
child: const Text('OK'))
],
);
}
}
class FeedbackPage extends StatefulWidget {
const FeedbackPage({super.key});
@override
State<FeedbackPage> createState() => _FeedbackPageState();
}
class _FeedbackPageState extends State<FeedbackPage> {
final nameOfuser = TextEditingController();
final emailOfuser = TextEditingController();
final messageOfuser = TextEditingController();
List<bool> isTypeSelected = [false, false, false, true, true];
@override
