Flutter GridView

In Flutter, GridView is a widget that creates a scrollable, multi-child grid layout. It allows developers to arrange its children in a two-dimensional grid, making it ideal for displaying collections of items such as images, text, or other widgets in a grid format. GridView automatically arranges its children in rows and columns, adjusting the layout based on available space and screen size.

In the below PDF we discuss about Flutter GridView in detail in simple language, Hope this will help in better understanding.

How to Implement GridView in Flutter?

Implementing a GridView in your Flutter app is straightforward. Here’s a basic example:

import 'package:flutter/material.dart';

void main() {

class MyApp extends StatelessWidget {
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Flutter GridView'),
body: GridView.count(
crossAxisCount: 2,
children: List.generate(20, (index) {
return Center(
child: Text(
'Item $index',
style: TextStyle(fontSize: 20),

In this example, we create a GridView with two columns and populate it with 20 text items.

Why Use GridView?

The versatility of GridView makes it an ideal choice for a wide range of applications:

  1. Dynamic Content: Whether you’re displaying images, text, or a combination of both, GridView adapts seamlessly to the content’s size and shape.
  2. Responsive Design: With GridView, you can create responsive layouts that adjust to different screen sizes and orientations, ensuring a consistent user experience across devices.
  3. Efficient Memory Usage: GridView automatically recycles its child widgets as they scroll off the screen, which helps optimize memory usage, especially when dealing with large datasets.
  4. Customization: From controlling the number of columns to specifying spacing between items, GridView offers a plethora of customization options to suit your design needs.


While the above example demonstrates a basic implementation of GridView, Flutter offers more advanced features to further enhance your layouts:

  • Custom Grid Items: Instead of simple text, you can use custom widgets as grid items, allowing for more complex and interactive UI elements.
  • Scroll Physics: Customize the scrolling behavior of your GridView by adjusting parameters such as scroll speed, friction, and elasticity.
  • Pagination: Implement pagination to load data incrementally as the user scrolls, which is especially useful when dealing with large datasets.
  • Dynamic Grids: Change the number of columns dynamically based on screen size or orientation using GridView.builder or GridView.custom.


In conclusion, Flutter GridView is a powerful and versatile widget for creating grid layouts in Flutter apps. With its customizable features, efficient scrolling behavior, and flexibility, GridView enables developers to build visually appealing and responsive user interfaces for a wide range of applications. Whether you’re creating an image gallery, a product catalog, or a social media feed, Flutter GridView provides the tools you need to bring your app’s UI to life.

Flutter’s GridView is a widget used to display a scrollable grid of widgets. It organizes its children into a two-dimensional scrolling grid.

You can handle item selection in a GridView by using the onTap or onLongPress properties of the child widgets within the GridView, or by wrapping the child widgets with GestureDetector widgets to detect gestures.

Yes, you can nest a GridView within another GridView in Flutter. This allows you to create complex grid layouts with multiple levels of nesting.

By default, a GridView in Flutter is scrollable if its content exceeds the available space. You can also wrap the GridView with a SingleChildScrollView or place it inside a ListView or CustomScrollView to enable scrolling.

To efficiently manage large lists in Flutter, you can use widgets like ListView.builder or GridView.builder, which create items dynamically as they are scrolled into view. This approach saves memory by only creating widgets for visible items.
