Question

I want to make filtration bar to filter the prices and the location. I am making a function at the end of the code that is checking wather the button is pressed or not to make retern the firebase filter.

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';
import 'package:realstate/home%20page/addingpage.dart';

import '../account page/account page.dart';

class Home extends StatefulWidget {
  const Home({Key? key}) : super(key: key);

  @override
  State<Home> createState() => _HomeState();
}

class _HomeState extends State<Home> {
  Stream<QuerySnapshot>? changer;
  CollectionReference Detabase =
      FirebaseFirestore.instance.collection('Detabase');
  bool sany = false;

  Stream<QuerySnapshot> snapshot = FirebaseFirestore.instance
      .collection('Detabase')
      .orderBy('expectedrent', descending: false)
      .snapshots();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        debugShowCheckedModeBanner: false,
        home: Scaffold(
          backgroundColor: Colors.white,
          appBar: AppBar(
            centerTitle: true,
            title: const Text(
              "Home",
              style: TextStyle(
                  color: Colors.black,
                  fontFamily: 'Montserrat',
                  fontWeight: FontWeight.bold,
                  fontSize: 32),
            ),
            leading: IconButton(

              ),
              onPressed: () {
