Example Staggered GridView #

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

class GridPageView extends StatefulWidget {
  @override
  _GridPageViewState createState() => _GridPageViewState();
}

class _GridPageViewState extends State<GridPageView> {

  List<StaggeredTileExtended> _listStaggeredTileExtended = const <StaggeredTileExtended>[
    const StaggeredTileExtended.count(2, 2),
    const StaggeredTileExtended.count(2, 1),
    const StaggeredTileExtended.count(1, 2),
    const StaggeredTileExtended.count(1, 1),
    const StaggeredTileExtended.count(2, 2),
    const StaggeredTileExtended.count(1, 2),
    const StaggeredTileExtended.count(1, 1),
    const StaggeredTileExtended.count(3, 1),
    const StaggeredTileExtended.count(1, 1),
    const StaggeredTileExtended.count(4, 1),
  ];

  List<Widget> _tiles = <Widget>[
