Custom Drag Start Animation

If you want to use your custom animation, you can do like this

        <DraggableGrid
          numColumns={4}
          renderItem={this.render_item}
          data={this.state.data}
          onDragStart={this.onDragStart}
          dragStartAnimation={{
            transform:[
              {scale:this.state.animatedValue}
            ],
          }}
        />
      </View>
    );
  }

  private onDragStart = () => {
    this.state.animatedValue.setValue(1);
    Animated.timing(this.state.animatedValue, {
      toValue:3,
      duration:400,
    }).start();
  }
