Flutter: GridTile examples

Last updated on December 11, 2021 A Goodman Loading... Post a comment

This article walks you through a few examples of using the GridTile widget in Flutter applications.

Overview

GridTile helps us quickly and easily create a tile with rich content (combination of text, images, and icons). This widget is often used with the GridView widget but it can be used as a standalone component.

Constructor:

GridTile({
  Key? key, 
  Widget? header, 
  Widget? footer, 
  required Widget child
})

If you want to make a one-line or two-line header/footer, you can use the GridTileBar widget:

GridTileBar({
  Key? key, 
  Color? backgroundColor, 
  Widget? leading, 
  Widget? title, 
  Widget? subtitle, 
  Widget? trailing
})

Now it’s time to write some code.

Examples

Social Network Photo Frame

This example creates a social network photo post frame (like what you can see on Instagram).

The code:

Scaffold(
      backgroundColor: Colors.deepPurple,
      body: Center(
        child: SizedBox(
          width: 360,
          height: 500,
          child: Card(
            elevation: 6,
            child: GridTile(
                header: GridTileBar(
                  backgroundColor: Colors.white,
                  leading: const CircleAvatar(
                    backgroundColor: Colors.deepOrange,
                    child: Text(
                      'K',
                      style: TextStyle(color: Colors.white, fontSize: 30),
                    ),
                  ),
                  title: const Text(
                    'KindaCode.com',
                    style: TextStyle(color: Colors.black),
                  ),
                  subtitle: const Text('5 minutes ago',
                      style: TextStyle(color: Colors.grey)),
                  trailing: IconButton(
                      onPressed: () {},
                      icon: const Icon(
                        Icons.more_vert_rounded,
                        color: Colors.black54,
                      )),
                ),
                child: Image.network(
                  'https://www.kindacode.com/wp-content/uploads/2021/12/sample-leaf.jpeg',
                  fit: BoxFit.cover,
                ),
                footer: GridTileBar(
                  backgroundColor: Colors.white,
                  title: Row(
                    children: const [
                      Icon(
                        Icons.favorite_outline,
                        color: Colors.grey,
                      ),
                      Text('20', style: TextStyle(color: Colors.black)),
                      SizedBox(
                        width: 20,
                      ),
                      Icon(
                        Icons.chat_bubble_outline,
                        color: Colors.grey,
                      ),
                      Text(
                        '5',
                        style: TextStyle(color: Colors.black),
                      ),
                    ],
                  ),
                  trailing: const Icon(
                    Icons.bookmark_outline,
                    color: Colors.black,
                  ),
                )),
          ),
        ),
      ),
    );

Creating a Grid of Products

This example creates a grid view that displays some fiction products. You will likely see this in commerce apps.

The complete code:

// main.dart
import 'package:flutter/material.dart';
import 'dart:math';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'KindaCode.com',
      theme: ThemeData(
        primarySwatch: Colors.green,
      ),
      home: const HomePage(),
    );
  }
}

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

  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  final List<Map> _products = List.generate(
      100,
      (index) => {
            "id": index,
            "name": "Product $index",
            "price": Random().nextInt(100)
          }).toList();
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('KindaCode.com'),
      ),
      body: GridView.builder(
          padding: const EdgeInsets.all(10),
          gridDelegate: const SliverGridDelegateWithMaxCrossAxisExtent(
              maxCrossAxisExtent: 200,
              childAspectRatio: 2 / 3,
              crossAxisSpacing: 20,
              mainAxisSpacing: 20),
          itemCount: _products.length,
          itemBuilder: (BuildContext ctx, index) {
            return GridTile(
              key: ValueKey(_products[index]['id']),
              child: Image.network(
                'https://www.kindacode.com/wp-content/uploads/2021/12/phone.jpeg',
                fit: BoxFit.cover,
              ),
              footer: GridTileBar(
                backgroundColor: Colors.black54,
                title: Text(
                  _products[index]['name'],
                  style: const TextStyle(
                      fontSize: 18, fontWeight: FontWeight.bold),
                ),
                subtitle: Text("\$${_products[index]['price'].toString()}"),
                trailing: const Icon(Icons.shopping_cart),
              ),
            );
          }),
    );
  }
}
