效果图

使用方法

DragLike(
  dragController: _dragController,
  duration: Duration(milliseconds: 520),
  child: imagelist.length <=0 ? Text('加载中...') : ClipRRect(
    borderRadius: BorderRadius.circular(10),
    child: TestDrag(src:imagelist[0])
  ), 
  secondChild: imagelist.length <= 1 ? Container(): ClipRRect(
    borderRadius: BorderRadius.circular(10),
    child:TestDrag(src:imagelist[1])
  ), 
  allowDrag: true,
  screenWidth: 375, 
  outValue: 0.6,
  dragSpeedRatio: 80,
  onChangeDragDistance: (distance){
    /// {distance: 0.17511112467447917, distanceProgress: 0.2918518744574653}
    print(distance.toString());
  },
  onOutComplete: (type){
    /// left or right
    print(type);
  },
  onScaleComplete: (){
    imagelist.remove(imagelist[0]);
    if(imagelist.length == 0) {
      loaddata();
    }
    setState(() {});
  },
  onPointerUp: (){
    
  },
  onCancel: (){
	print('取消了');
  },
),

回调方法

onOutComplete

onOutComplete: (type){
	/// left or right
	print(type);
},

onScaleComplete

onScaleComplete: (){
	imagelist.remove(imagelist[0]);
	if(imagelist.length == 0) {
		loaddata();
	}
	setState(() {});
},

onChangeDragDistance

1. distance滑动距离，0-1，超过设置的值将会划出widget
2. distanceProgress，根据设置的划出边界值的百分比，0-1+，方便做一些特效，超过1即代表松手就会划出边界

onChangeDragDistance: (distance){
	/// {distance: 0.17511112467447917, distanceProgress: 0.2918518744574653}
	print(distance.toString());
},

onPointerUp

onPointerUp: (){

},

onCancel

onCancel: (){

},

控制器

_dragController.toLeft(completeTag: 'custom_left');

_dragController.toRight(completeTag: 'custom_right');
