Implementing Staggered Grid View

This layout is ideal for displaying a collection of items with different heights, such as images, cards, or tiles.

Setting Up the Project

Before we begin, ensure you have Flutter installed and set up on your system. Create a new Flutter project using the following command:

flutter create staggered_grid_view_demo

Adding Dependencies

In your pubspec.yaml file, add the flutter_staggered_grid_view package to your dependencies:

dependencies:
  flutter:
    sdk: flutter
  flutter_staggered_grid_view: ^1.0.0

Import the package:

import 'package:flutter_staggered_grid_view/flutter_staggered_grid_view.dart';

Creating the Staggered Grid View

Step 1: Prepare the List of Items

Create a list of items that you want to display in the staggered grid view. For this example, we'll use a list of images.

List imageUrls = [
  'https://example.com/image1.jpg',
  'https://example.com/image2.jpg',
  'https://example.com/image3.jpg',
  // Add more image URLs as needed
];

Step 2: Build the Staggered Grid View Widget

In the build method of your widget, create the staggered grid view using the StaggeredGridView.countBuilder widget.

StaggeredGridView.countBuilder(
  crossAxisCount: 2,
  itemCount: imageUrls.length,
  itemBuilder: (BuildContext context, int index) {
    return Container(
      decoration: BoxDecoration(
        color: Colors.grey,
        borderRadius: BorderRadius.circular(8.0),
      ),
      child: Image.network(imageUrls[index], fit: BoxFit.cover),
    );
  },
  staggeredTileBuilder: (int index) {
    return StaggeredTile.count(1, index.isEven ? 1.2 : 1.5);
  },
  mainAxisSpacing: 8.0,
  crossAxisSpacing: 8.0,
)
