# flutter_draggable_gridview
This package supports drag & drop widgets inside the GridView.builder for multiplatform. It provides all the properties which are available in Gridview.builder and easy to implement with the few lines of code.
### Draggable GridView.
## Usage
### Example
```dart
DraggableGridViewBuilder(
gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
childAspectRatio: MediaQuery.of(context).size.width / (MediaQuery.of(context).size.height / 3),
),
children: _listOfDraggableGridItem,
isOnlyLongPress: false,
dragCompletion: (List list, int beforeIndex, int afterIndex) {
print( 'onDragAccept: $beforeIndex -> $afterIndex');
},
dragFeedback: (List list, int index) {
return Container(
child: list[index].child,
width: 200,
height: 150,
);
},
dragPlaceHolder: (List list, int index) {
return PlaceHolderWidget(
child: Container(
color: Colors.white,
),
);
},
);
```
### Required parameters
##### gridDelegate:
A delegate that controls the layout of the children within the GridView.
##### children:
This property contains list of [DraggableGridItem] and it is use to show the widget inside the GridView.builder to provide the drag & drop functionality. Also, it contains isDraggable parameter which manages enable/disable the drag & drop functionality.
##### dragCompletion:
This callback provides updated list and old and new indexes.
### Optional parameters
##### isOnlyLongPress:
This property contains ```bool``` value. If this property is ```false``` then it works with simple press draggable or else it works with long press. default value is 'true'.
##### dragFeedback:
With this callback, you have to return a Widget and we will use this widget in feedback. Learn more about feedback from [Draggable](https://api.flutter.dev/flutter/widgets/Draggable-class.html#:~:text=Draggable%20class%20Null%20safety,user's%20finger%20across%20the%20screen) class.
##### dragPlaceHolder:
TWith this callback, you have to return a PlaceHolderWidget and we will use this widget in place holder.
##### dragChildWhenDragging:
With this callback, you have to return a Widget and we will display this widget instead of child when drags are under way. Learn more about childWhenDragging from [Draggable](https://api.flutter.dev/flutter/widgets/Draggable-class.html#:~:text=Draggable%20class%20Null%20safety,user's%20finger%20across%20the%20screen) class.
### Last But Not Least :heart_eyes:
#### You can use all the ```GridView.builder``` properties with ```DraggableGridViewBuilder``` class.
## Note:
The result returns in List. so it can be lost later, you are responsible for storing it somewhere permanent (if needed).
