Usage

Import the package

import 'package:flutter_dynamic_staggered_grid_view/flutter_dynamic_staggered_grid_view.dart';

Basic Usage Example

import 'package:flutter/material.dart';
import 'package:flutter_dynamic_staggered_grid_view/flutter_dynamic_staggered_grid_view.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Staggered Grid Example')),
        body: Padding(
          padding: const EdgeInsets.all(8.0),
          child: StaggeredGrid.count(
            crossAxisCount: 4,
            mainAxisSpacing: 4.0,
            crossAxisSpacing: 4.0,
            children: List.generate(20, (index) {
              return Container(
                color: Colors.teal[100 * (index % 9)],
                height: (index % 7 + 1) * 100,
                child: Center(child: Text('Tile $index')),
              );
            }),
          ),
        ),
      ),
    );
  }
}

Customizing the Grid

You can customize the grid by specifying the crossAxisCount, mainAxisSpacing, and crossAxisSpacing properties:

StaggeredGrid.count(
  crossAxisCount: 4,
  mainAxisSpacing: 8.0,
  crossAxisSpacing: 8.0,
  children: List.generate(20, (index) {
    return Container(
      color: Colors.blue[100 * (index % 9)],
      height: (index % 5 + 1) * 100,
      child: Center(child: Text('Tile $index')),
    );
  }),
)

GridView Builder

The StaggeredGridView.countBuilder is a powerful and flexible way to create staggered grid layouts. It allows you to dynamically build grid items and customize their appearance and behavior. Here's an example:

StaggeredGridView.countBuilder(
  physics: NeverScrollableScrollPhysics(),
  shrinkWrap: true,
  crossAxisCount: 2,
  itemCount: 4,
  itemBuilder: (context, index) => Container(
    height: 200 * index.toDouble(),
    color: Colors.blue,
    child: Center(child: Text('Item $index')),
  ),
  staggeredTileBuilder: (index) => StaggeredTile.fit(1),
  mainAxisSpacing: 10.0,
  crossAxisSpacing: 10.0,
)

physics: Controls the scroll behavior of the grid. Setting it to NeverScrollableScrollPhysics() - makes the grid non-scrollable.
shrinkWrap: If set to true, it reduces the size of the grid to fit the content. This is useful - when the grid is used inside another scrollable widget.
crossAxisCount: Defines the number of columns in the grid.
itemCount: Specifies the number of items in the grid.
itemBuilder: Builds the grid items dynamically. Here, each item is a Container with a height - proportional to its index.
staggeredTileBuilder: Defines the layout of each tile. In this example, each tile takes up one - column.
mainAxisSpacing and crossAxisSpacing: Define the spacing between the tiles.
