Overview

drag_select_grid_view

A grid that supports both dragging and tapping to select its items.

Basic usage

DragSelectGridView constructor is very similar to GridView.builder, so you should take your time to understand the latter before diving into this library.

Once you are familiar with GridView.builder, probably the only additional piece of information you'll need is DragSelectGridViewController. With it, you're able to know which indexes are selected.

Check this example:

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final controller = DragSelectGridViewController();

  @override
  void initState() {
    super.initState();
    controller.addListener(scheduleRebuild);
  }

  @override
  void dispose() {
    controller.removeListener(scheduleRebuild);
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: SelectionAppBar(
        selection: controller.value,
      ),
      body: DragSelectGridView(
        gridController: controller,
        itemCount: 20,
        itemBuilder: (context, index, selected) {
          return SelectableItem(
            index: index,
            selected: selected,
          );
        },
        gridDelegate: SliverGridDelegateWithMaxCrossAxisExtent(
          maxCrossAxisExtent: 80,
        ),
      ),
    );
  }

  void scheduleRebuild() => setState(() {});
}

As you may have noticed in the code above, DragSelectGridView must be used along two other widgets in order to provide a proper user experience. In the example, they are:

SelectableItem: A selectable widget, which is going to visually indicate whether the item is selected or not.
SelectionAppBar: A custom AppBar, which shows the amount of selected items and an option to unselect them.

The example project provides some samples of those widgets. I won't add them to the library, since they are unrelated to the grid itself, but feel free to copy them into your project, as long as you respect the license terms.

Advanced usage

You can use the setter DragSelectGridViewController.value to directly change the selection (I'm not quite sure why you'd need this, but I don't ask questions).

It allows this sort of interaction:

You can check the code here.

There are some other minor settings you can do to make DragSelectGridView fit your needs, like DragSelectGridView.autoScrollHotspotHeight and DragSelectGridView.unselectOnWillPop. Those features are well documented, so I'll let you take your discovery time.

Hopefully, this is everything you need to know to use this library.

Thanks ❤️

Once upon a time I asked at Flutter Study Group how to implement a specific feature that I intended to add to this library. Simon Lightfoot offered to help me and effortlessly implemented what eventually became part of this library (check this gist). A big thanks to him.

I took a lot of inspiration from Aidan Follestad's Android implementation, drag-select-recyclerview. Also a big thanks to him.

Scrolling not working

hello, you have done a perfect work for sliding back and onTap to select.

i think there a little issue now, we cant scroll vertically if the items is more than the phone screen.

how can i set border radius for gridview?

for GridView of flutter feature i can use ClipRRect or Card to make border radius for around items, but in this library it doesn't work

for example this code work fine with border radius

child: Card(
  elevation: 0.0,
  clipBehavior: Clip.antiAliasWithSaveLayer,
  shape: const RoundedRectangleBorder(
      borderRadius: BorderRadius.only(
        topLeft: Radius.circular( 8.0 ),
        topRight: Radius.circular( 8.0 ),
      ) ),
  child: StreamBuilder<List<MediaModel>>(
      stream: _globalBloc.storageMediaBloc.imagesMedia$,
      builder: (context, snapshot) {
        ...
        return GridView.builder(
          controller: scrollController,
          cacheExtent: 100,
          gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(

detect long press end

Is it possible to detect when a drag is completed? I tried adding a GestureDetector as the parent widget but it just seems to break the DragSelectGridView widget.

Single click selection

Hi Hugo,

I had the need to enable selection of one or more items via single click so I forked your project. In case you want to merge this to master you can accept this PR.

Need to pop twice after selecting

Whenever a user selects anything in de grid, I need to pop twice to go to the previous page. The first time, the selection dissapears, the second time we actually go to the previous page.

When selection doesn't get changed, pop works the first time.

Item selection when list is empty
Hi!

Is there a way to enable selecting items if selectedIndexes list is empty?

It would be great if we have controls of this isSelecting setting.

/// Whether any item got selected. bool get isSelecting => selectedIndexes.isNotEmpty;

DragSelectGridViewController disposed prematurely

Consider the following code :

import 'package:flutter/services.dart';
import 'package:flutter/material.dart';
import 'package:drag_select_grid_view/drag_select_grid_view.dart';

import 'selectable_item.dart';
import 'selection_app_bar.dart';

void main() {
  SystemChrome.setSystemUIOverlayStyle(
    SystemUiOverlayStyle(statusBarColor: Colors.grey[200]),
  );
  runApp(
    MaterialApp(
      home: MyApp(),
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primaryColor: Colors.white,
        accentColor: Colors.white,
        scaffoldBackgroundColor: Colors.white,
        appBarTheme: const AppBarTheme(elevation: 2),
      ),
    ),
  );
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final controller = DragSelectGridViewController();

  @override
  void initState() {
    super.initState();
    controller.addListener(scheduleRebuild);
  }

  @override
  void dispose() {
    controller.removeListener(scheduleRebuild);
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: SelectionAppBar(
        selection: controller.selection,
        title: const Text('Grid Example'),
      ),
      body: PageView(
        children: [
          Column(
            children: [
              Center(
                child: Text('first page'),
              )
            ],
          ),
          DragSelectGridView(
            gridController: controller,
            padding: const EdgeInsets.all(8),
            itemCount: 90,
            itemBuilder: (context, index, selected) {
              return SelectableItem(
                index: index,
                color: Colors.blue,
                selected: selected,
              );
            },
            gridDelegate: const SliverGridDelegateWithMaxCrossAxisExtent(
              maxCrossAxisExtent: 150,
              crossAxisSpacing: 8,
              mainAxisSpacing: 8,
            ),
          ),
        ],
      ),
    );
  }

  void scheduleRebuild() => setState(() {});
}

It gave the following error when I switched between Page 1 to Page 2 to Page 1 to Page 2

Looks like the controller is disposed but not initiated again. The state on the appbar is still retained. Can you please help ?

about pop twice after selecting cause some problems
HI, I am new to flutter and have some question about the pop twice after selecting. I know when select the grid with longpress will in drag_select mode, but there's not have a onTap to switch on it. To solve it I use another GestureDetector with onTap to separated those two function and it work fine on select grid.

onTap like this GestureDetector( onTap: () { widget.selectedImages(widget.url); debugPrint(" ${widget.isSelected}"); debugPrint(" ${scaleAnimation.value}"); }, ),

But because onTap don't need to pop twice, when I use cancel button, I can't know which is onTap, which is longpress.

How do I know the drag_select mode is trigger or not ? Beacause If I knew, I can pop When I want.

And how to I return itembuilder status to the father layer?

Another question is about scroll, I use SmartRefresher now, and if I add a DragSelectGridView in SmartRefresher child, the Refresher will not work. And if I add nerverScrollPhysis on DragSelectGridView, it can refresh widget but can't scroll the grid.

If you read this, I will appreciate you. Thank you for your reading.

is there a way to enable onTap, will deselect all and tap the item that is newly tapped?

First of all, i'm loving this library. everything work nicely except I wish i could set a mode where I tap to deselect all others that is currently selected, and select the one that is tapped

if i used the advanced mode "triggerSelectionOnTap" to true, tapping non selected item will select it, and tapping already selected will unselect it,

I wish there is a mode where it is more natural feel like in windows/linux/mac where tapping the unselected ones will deselect all and select the new one only.

How to get the select parameter outside the Gridview ?
Hi . I am using the SelectableItem , that was created in the example code . It needs the selected parameter which needs to be passed from the itembuilder function :

itemBuilder: (BuildContext context, int index, bool selected) { return _mediaList[index]; }),

The Problem is as you can see that i am storing the SelectableItem in a mediaList variable. So i want to find a way to get the selected parameter to get passed to the SelectableItem.
