[Discussions] 使用ExtendedImageGesturePageView的时候，双指放大图片不是很灵敏

用食指和中指向俩边滑动以放大图片，但总会识别成左右切换图片。

我是直接下载demo运行在安卓手机上，下面是测试的视频。

I also think it needs to be optimized.

[chenshandong]

我也遇到同样的问题

[zmtzawqlp]

extended_image/lib/src/gesture_detector/drag_gesture_recognizer.dart

Line 13 in 7b444ab

if (_velocityTrackers.keys.length == 1) {

可以自定义下这里的规则，这就是手势冲突问题，这个就要看个人的习惯了。。比如有2以上触摸点的时候，就让水平垂直的手势不获胜。

[QixianWu]

优化后，体验有所提升
if(_velocityTrackers.keys.length >=2){
return false;
}

[zmtzawqlp]

怎么说呢，这个算是个人的感知吧，这地方就是为了更进一步区分是垂直水平拖动还是 双指多指缩放的

Is there any way to control this externally?
can modify the library code after receiving the pull, but I would like to avoid that method as much as possible.

we can't public it , it has much private properties, so you can fork this package, and custom your logic

Thanks for the reply.
If you can't make it public, it seems like gesture recognition for pinch zoom and page switching needs to be improved.

我也遇到了，缩放非常不流畅，缩放手势会跟滑动手势冲突，应该修改下手势竞争规则

[chinghoi]

缩放经常不成功, 缩放的时候会走左右滑动的手势

[lakatosdavid]

yes this should be fixed! please very annoying

[chenjiangmin]

@zmtzawqlp 请问下这个可以优化么 确实有些奇怪
