Displaying Data in a Grid View

This example illustrates how to create a grid layout to display images or items.

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Grid View Example',
      theme: ThemeData(primarySwatch: Colors.blue),
      home: GridViewExample(),
    );
  }
}

class GridViewExample extends StatelessWidget {
  final List<String> _images = [
    'https://via.placeholder.com/150',
    'https://via.placeholder.com/150',
    'https://via.placeholder.com/150',
    'https://via.placeholder.com/150',
    'https://via.placeholder.com/150',
    'https://via.placeholder.com/150',
  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Grid View Example')),
      body: GridView.builder(
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
          crossAxisCount: 2,
          childAspectRatio: 1,
        ),
        itemCount: _images.length,
        itemBuilder: (context, index) {
          return Card(
            child: Image.network(
              _images[index],
              fit: BoxFit.cover,
            ),
          );
        },
      ),
    );
  }
}
