How do I get GridView.builder to take up the remainder of the screen in flutter and scroll with another two widgets

I am having trouble getting my GridView.builder to scroll with the two widgets above it at the same time. I only want the search bar to remain on the screen when I am scrolling. The only way I have managed to hack it is by using a SizedBox but I want it to fill up whatever mobile device it is on.

Any help would be appreciated. I have marked the point I want it to scroll from in the code in capital letters.

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter/widgets.dart';

import '../widgets.dart/search_results_chip.dart';

class ItemSearchResults extends StatelessWidget {
  const ItemSearchResults({super.key});

  @override
  Widget build(BuildContext context) {
    return SafeArea(
        child: Column(
      children: [
        //search bar
        Row(
          children: [
            IconButton(
              onPressed: () {},
              icon: const Icon(Icons.arrow_back),
            ),
            Expanded(
              child: TextField(
                decoration: InputDecoration(
                    isCollapsed: true,
                    prefixIcon: const Icon(Icons.category),
                    suffixIcon: const Icon(Icons.search),
                    border: OutlineInputBorder(
                        borderRadius: BorderRadius.circular(30))),
              ),
            ),
            IconButton(
                onPressed: () {}, icon: const Icon(Icons.filter_alt_outlined))
          ],
        ),

        ),

        //search results

Wrap your GridView.builder with SizedBox instead of Expanded

 //Search Results
  SizedBox(
    child: GridView.builder(),
  ),

Result Screen -
