Try flutter_staggered_grid_view package.

In the pubspec.yaml , add the following dependency:

dependencies:
  flutter_staggered_grid_view: any

In your library , add the following import:

import 'package:flutter_staggered_grid_view/flutter_staggered_grid_view.dart';

Example:

  StaggeredGridView.countBuilder(
  crossAxisCount: 4,
  itemCount: 8,
  itemBuilder: (BuildContext context, int index) => new Container(
      color: Colors.green,
      child: new Center(
        child: new CircleAvatar(
          backgroundColor: Colors.white,
          child: new Text('$index'),
        ),
      )),
  staggeredTileBuilder: (int index) =>
      new StaggeredTile.count(2, index.isEven ? 2 : 1),
  mainAxisSpacing: 4.0,
  crossAxisSpacing: 4.0,
),

Use it like GridView

Output:

Constructors :

The StaggeredGridView follow the same constructors convention than the GridView. There are two more constructors: countBuilder and extentBuilder. These constructors allow you to define a builder for the layout and a builder for the children.

Tiles :

A StaggeredGridView needs to know how to display each tile, and what widget is associated with a tile.

A tile needs to have a fixed number of cell to occupy in the cross axis. For the extent in the main axis you have 03 options:

1. You want a fixed number of cells => use StaggeredTile.count.
2. You want a fixed extent => use StaggeredTile.extent.
3. You want a variable extent, defined by the content of the tile itself => use StaggeredTile.fit.
