PhotoViewGestureDetectorScope class

An InheritedWidget responsible to give a axis aware scope to PhotoViewGestureRecognizer.

When using this, PhotoView will test if the content zoomed has hit edge every time user pinches, if so, it will let parent gesture detectors win the gesture arena

Useful when placing PhotoView inside a gesture sensitive context, such as PageView, Dismissible, BottomSheet.

Usage example:

PhotoViewGestureDetectorScope(
  axis: Axis.vertical,
  child: PhotoView(
    imageProvider: AssetImage("assets/pudim.jpg"),
  ),
);
