### NineGridView
类似微博动态，微信朋友圈，展示图片的九宫格控件。支持单张大图预览。
同时也支持微信群组，钉钉群组，QQ讨论组头像效果。
### DragSortView
类似微博/微信发布动态选图九宫格。支持按压放大效果，拖拽排序，拖拽到指定位置删除。
### Pub
```yaml
dependencies:
nine_grid_view: #latest version
```
### Example
```yaml
import 'package:nine_grid_view/nine_grid_view.dart';
// bigImage参数 单张大图建议使用中等质量图片，因为原图太大加载耗时。
NineGridView(
margin: EdgeInsets.all(12),
padding: EdgeInsets.all(5),
space: 5,
type: NineGridType.weChat,
itemCount: itemCount,
itemBuilder: (BuildContext context, int index) {},
);
// 头像需要设置宽、高参数。
NineGridView(
width: 120,
height: 120,
padding: EdgeInsets.all(5),
space: 5,
type: NineGridType.qqGp, //NineGridType.weChatGp, NineGridType.dingTalkGp
itemCount: itemCount,
itemBuilder: (BuildContext context, int index) {},
);
// 建议使用略微缩图，因为原图太大可能会引起重复加载导致闪动.
DragSortView(
imageList,
space: 5,
margin: EdgeInsets.all(20),
padding: EdgeInsets.all(0),
itemBuilder: (BuildContext context, int index) {},
initBuilder: (BuildContext context) {},
onDragListener: (MotionEvent event, double itemWidth) {
/// 判断拖动到指定位置删除
/// return true;
if (event.globalY > 600) {
return true;
}
return false;
},
);
```
