A generic [Flutter](https://flutter.dev) item selector that works with

ListView, GridView, Row, Column, or basically any parent widget that

can have indexed child widgets. It supports single-selection by tap,

and multi-selection by long-press and drag with auto-scrolling.

## Preview

| ListView | GridView |

|:---:|:---:|

| ![ListView](https://raw.githubusercontent.com/jpnurmi/item_selector/master/doc/images/listview.gif "ListView") | ![GridView](https://raw.githubusercontent.com/jpnurmi/item_selector/master/doc/images/gridview.gif "GridView") |

| Column | Custom |

|:---:|:---:|

| ![Column](https://raw.githubusercontent.com/jpnurmi/item_selector/master/doc/images/column.gif "Column") | ![Custom](https://raw.githubusercontent.com/jpnurmi/item_selector/master/doc/images/custom.gif "Custom") |

## Usage

To use this package, add `item_selector` as a [dependency in your pubspec.yaml file](https://flutter.io/platform-plugins/).

```dart

ItemSelectionController(

  child: ListView(

    children: List.generate(10, (int index) {

      return ItemSelectionBuilder(

        index: index,

        builder: (BuildContext context, int index, bool selected) {

          return Text('$index: $selected');

        },

      );

    }),

  ),

)

```

Item Selector is based on [Multi Select GridView in Flutter - by Simon Lightfoot](https://gist.github.com/slightfoot/a002dd1e031f5f012f810c6d5da14a11).
